Round up: Best free Microsoft Office alternatives 2016

Introduction

With Office 2016, Microsoft has made several enhancements to security and productivity, including a much-needed overhaul of Excel. However, at £120 (US$120, AU$179) for the home edition it's a substantial investment - especially if you're unlikely to use its more advanced features regularly.

Microsoft's cloud-based Office 365 has a lower entry price of £8 (US$10, AU$12) per month or £80 (US$90, AU$119) per year for the home version, but again, it's a substantial expense for a set of tools that might be overpowered for your needs.

If you work with people who use Office and rely on its collaborative functions every day, the convenience of using those programs yourself may well justify the price. For the rest of us, there are lots of excellent free alternatives to consider. Here are our picks of the best free office apps in 2016. Have we missed your preferred suite? Let us know in the comments below.

Remember, when you install any of these office suites you'll be asked if you want to associate particular file formats with the newly installed programs. We recommend deselecting these options at first, then changing your defaults once you're satisfied that you'll be using the new suite in the long term.

LibreOffice

LibreOffice is a fork of the OpenOffice.org project, and it's available for Windows, OS X and Linux (it's the office suite you'll find on most popular Linux distros). The main draw is that it's OpenOffice but fast-tracked, with far more frequent updates than its parent suite.

Download LibreOffice free

Like OpenOffice, it's designed around the standard Open Document Format with Microsoft Office importing and exporting, and its six apps cover just about everything you could need from a productivity suite:

  • Writer (word processing
  • Calc (spreadsheets)
  • Impress (presentations)
  • Draw (diagrams and vector graphics)
  • Math (mathematical formulae)
  • Base (databases)

Download LibreOffice freeUnlike Microsoft Office there's no email client - likely because there are so many excellent open source clients already available, developing another would be redundant.

LibreOffice's apps have a clear format reminiscent of older versions of Microsoft Office. It's not as sleek as Office 2016 or 365, but features are represented by large, clear icons rather than being hidden behind menus and ribbons. See our guide to getting started with LibreOffice.

If its standard offering isn't enough, the LibreOffice community has created hundreds of templates and extensions to add new features and improve existing ones - all available to download and use completely free. There's also a portable version that can be run from a USB stick.

Read on to discover more of the best free Microsoft Office alternatives.

Apache OpenOffice

If LibreOffice does everything Apache OpenOffice does and gets updates more quickly, why would you consider its less action-packed parent? The short answer is stability: a faster update cycle can mean the potential to introduce new bugs.

Download OpenOffice free

Download OpenOffice freeOpenOffice contains the same six core apps as LibreOffice (Writer, Calc, Impress, Draw, Math and Base) and its interface is very similar. It lacks some of the features of LibreOffice (such as live word counts in Writer), but the two suites share so much of the same code, such differences are few and far between.

Again, a portable version is available for use from a removable USB device or cloud storage service.

SoftMaker FreeOffice

SoftMaker FreeOffice is available for Windows and Linux (and there's a companion app for Android) and offers effortless editing of Microsoft Word, Excel and PowerPoint files. It can also export files in EPUB and PDF export.

Download SoftMaker FreeOffice free

Download SoftMaker FreeOffice freeFreeOffice contains three apps delivering the familiar combination of word processing, spreadsheets and presentations. While the feature set isn't quite as extensive as LibreOffice - it lacks mail merging, and the spreadsheets' charts aren't as spectacular - it's faster, can open password-protected Office and WordPerfect documents (provided you know the password) and covers the basics very well.

As with LibreOffice and OpenOffice, SoftMaker provides a portable version of FreeOffice for Linux and Windows.

WPS Office 2016

WPS Office 2016, also known as Kingsoft Office, is one of the best Microsoft Office-a-likes, but the free version does include some important caveats. The free version for Windows begins a 30-day trial of the Premium version (it reverts to the free version if you don't open your wallet at the end of the month) and printed documents are watermarked.

Download WPS Office free

Download WPS Office 2016 freeIt's available for Windows, Linux, iOS and Android, and includes apps for word processing, presentations and spreadsheets (hence the name WPS).

It borrows the ribbon interface from newer versions of Office, so you'll be up and running in no time, but the drawbacks of the free edition might be enough to put you off.

Google Docs

If you're looking for a serious Office rival, Google Docs should be towards the top of your list. What started life as a free but basic cloud-based Office suite has evolved into something that's deceptively powerful, and even the weakest app, PowerPoint alternative Slides, is rather good these days.

Google Docs

Google Docs is particularly good for teamwork, with excellent multi-user support and change tracking, and the companion mobile apps cover iOS as well as Android. If you're in the kind of environment where documents, spreadsheets or presentations are pinged back and forth, with comments and tracked changes, Google Docs will make your life simpler.

Zoho Docs

Zoho Docs is used by the likes of the BBC, Coca-Cola and ITV, and its free service gives up to 25 users 5GB of storage each.

Zoho Docs

It includes three cloud-based apps - the usual spread of word processing, spreadsheet and presentations - as well as document versioning and desktop syncing.

There are companion apps for iOS and Android, as well as integration with other services such as Dropbox and Google Drive. That makes it particularly attractive to small businesses, although it's important to note that some of the more advanced features such as password-protected sharing aren't available in the free version.

Don't plump for Google Docs without checking out Zoho first.

Software : Are we entering the post-app era?

Software : Are we entering the post-app era?


Are we entering the post-app era?

Posted:

Are we entering the post-app era?

Introduction and blame the browser

What would a 'world beyond apps' be like? It's hard to imagine using a smartphone that doesn't have any apps, and yet there has been talk of the 'post-app era' for some time. Cue futuristic ways of interacting with computers and data, with virtual assistants and natural language processing at the forefront.

However, few think that apps are going to disappear completely, only that the way we interact with them will change. "In the near-term we will see a demise of individual apps at the front-end, with instant messaging and social media interfaces used as a gateway into technologies," says Claus Jepsen, Chief Architect at business software company Unit4.

So will we still be physically opening apps in a few years? Probably not, but that trend started when push notifications appeared on our phones long ago. Since then, apps have added always-on functionality, background monitoring, interactive notifications, integration with wearables, and automatic updates.

Now get ready to watch as apps are consumed within contextually-aware virtual assistants like Siri – and almost completely disappear.

Apps on the rise… and fall

Ever since the creation of the smartphone, the App Store has been a battleground between Apple and Android. So who won? Although apps in Apple's App Store make the most money, they accounted for just 15% of all apps downloaded in 2015. IDC reports that Apple's share fell 8% from the previous year – quite a tumble, and largely down to the massive volume of Android-based phones being sold around the globe.

"While IDC forecasts that mobile app installs and direct revenues will continue to grow over the coming years, it also expects that growth to slow considerably," says Michael Allen, Solutions VP at application performance management software company Dynatrace. "For businesses, this offers a wake-up call that the mobile race is starting to reach its climax – consumers are reaching app saturation, and they're now looking for quality over quantity."

That's borne out by Dynatrace's own research, which found that nearly half (47%) of people will only give an app three seconds to load before they give up and go elsewhere, while nearly a third (32%) will never try it again if it doesn't work the first time.

Jamie Turner is CEO of PCA Predict

Blame the browser?

It's not always the apps' fault – some apps lose their shine over time. Remember that flashlight app on your phone? Now it's built into the phone itself. There are speciality camera apps, polished email apps and countless pointless brand apps, but few of them add much to what your phone can already do. Besides, the mobile web is getting more app-like every day.

"It really depends on what we mean by an app," says Jamie Turner, CEO of address verification and data quality services company PCA Predict. "Many apps are little more than website bookmarks pointing to a mini-site that looks and feels like something that's native."

Turner thinks that we only have native apps because they operate without the performance and security limitations of a browser. "This is changing fast with significant work being placed into newer browser technology that feels as fast as native apps and more sensible security models," he adds.

However, even slick mobile websites can't get round the inherent problem with apps; their scope is very limited. Spotify aside (its 30 million tracks make this service the de facto web-based music library), how many apps do anything other than give you access to a walled garden of content?

Nobody wants to use the Uber or Lyft apps specifically, they want to get a ride. It's the same with Netflix. Rather than go hunting for a particular movie and failing to find it, wouldn't it be easier if your phone just told you where to find that movie?

Apps like Uber would be better consumed into a 'smart agent' that can access all ride apps

Goodbye apps, hello smart agents

We've fallen out of love with apps, and that's not going to change. Gartner predicts that by 2020, smart agents will facilitate 40% of mobile interactions, and that 'post-app era' will begin to dominate. For 'smart agent', read virtual private assistants like Google Now, Cortana, Siri and Alexa, each stuffed with so-called 'learning algorithms' and artificial intelligence.

These agents will be the principal way that we navigate information. "No longer will you have to load a specific application," says Gartner. "The algorithms on the systems that you touch will understand your needs and serve you the correct data in context." The future is algorithms, not apps.

App aggregation and the post-app future

App aggregation

The services that apps offer are already being consumed en masse by virtual private assistants. "Siri is already an example of aggregation‎ as it enables the user to perform multiple tasks such as checking the weather, searching online, sending an email, scheduling a meeting, and many other things," says Magnus Jern, President of mobile enterprise tech firm DMI International, who thinks we're on the cusp of sophisticated aggregation services.

"Facebook will do it with Messenger and new third-party services' APIs for chatbots etc, and WeChat and Line already do this," he says of instant messaging apps that are fast becoming 'smart agent' platforms themselves. But will aggregation services actually replace apps? "Not in the short-term, because depending on the use case, apps will still provide a better experience for a lot of our daily tasks," says Jern. "Instead the aggregation services will integrate with the standalone apps."

However, that does suggest that the most popular, wealthy and ambitious apps – such as Facebook and WeChat – are at least as well positioned as OS developers Apple and Google to create the dominant new virtual assistant platforms.

The spoken word

How we interact with the services currently offered by apps will change, too. The smart money is on voice. "Interaction models are changing," says Frank Palermo, Executive VP for Global Digital Solutions at IT services company VirtusaPolaris, who thinks that with advances in AI-powered virtual assistants, voice will soon be at the centre of the user experience. A supercharged, more conversational Siri (and other assistants) will effectively make individual apps redundant.

"You no longer need to click on your phone and open an app," adds Palermo, "it is a much more immersive experience where you are interacting with your device in a more conversational way – it literally becomes your pocket PA."

Is natural language good enough?

Not quite yet. Siri is getting cleverer, certainly, but doesn't understand everything it's told. Ditto Nuance's Dragon Dictation; every year it gets less muddled and more accurate. "We are very close to having natural language being the primary means of interacting with the software," thinks Jepsen, who predicts a 'conversational experience'.

"Rather than navigate screens, tools and clunky interfaces, employees will be able to type or say 'show me my payslip' or 'complete my expenses'," says Jepsen, whose Unit4 company has created a digital assistant for workplaces called Wanda that inserts itself into existing apps. "We don't need to build our own screens or apps to accommodate this, we can use somebody else's, like Skype for Business, Twitter, or Facebook," he adds. "Everything will become easier, it will become natural."

Will virtual assistants like Siri consume all apps?

The post-app future

Apps are on the watch-list, and are already being phased out. That's no surprise to some, who think they're inherently unnatural. "Clicking through buttons is not natural human behaviour," says Palermo, who believes we're moving towards a more immersive and ambient world, where it's possible for people to have a natural discussion with their surroundings.

"We won't need to type, we will just speak and our device will present the information we need in a visual way – perhaps by combining with virtual reality to help us visualise our answers," adds Palermo. Either way, the era where smartphone users launched apps individually is soon going to seem archaic.

Google app on iOS catches up to Android

The Google app for iPhone and iPads is getting a juicy update today that will help load pages faster.

The search giant announced a major update to the Google app for iOS, bringing Accelerated Mobile Pages (AMP) along for the ride. AMP works similarly to Facebook's Instant Articles technology as both companies try to speed up web browsing.


Google AMP pagesThe feature loads a mobile-optimized version of a web page that strips out superfluous elements. The page still loads ads to ensure sites make money, but restricts the interactivity of pages by limiting the use of JavaScript. The resulting pages are tailored for reading on a small screen.

Beyond AMP, the app promises faster loading, though Google even admits users may not notice the slight speed bump.

Lastly, the Google app update on iOS brings sports highlights to Google Now, the company's intelligent mobile assistant. You'll be able to watch game lights directly from Google Now cards instead of having to navigate to a site to load the video.

Today's update brings iPhone and iPad users up to speed with some of Android's features, a reason to rejoice if you're on Apple's platform.

Google has been working hard to bring its apps and services to its own Android platform and as well as iOS. The company announced its artificially intelligent chat app, Allo, and video call app, Duo, are coming to Android and iOS at the same time.

Round up: Best free PDF readers 2016

Download the best free PDF readers

When you need to open a PDF, you'll usually opt for one of two options: the Reader app for Windows 8 and 10 (often pre-installed with the operating system, or available from the Windows Store), or trusty stalwart Adobe Reader.

Both are solid options, but there are many other free options, each with its own advantages. If you want to merge documents, convert them to a different format or extract images, there's a free tool that will make it straightforward.

If you're short on drive space, there are also ultra-lightweight viewers available that will occupy under two megabytes (compared to Adobe Reader, which takes up 148MB), plus portable apps that run directly from a USB stick.

After installation, each of these programs will ask if you want to make it your default PDF reader. We recommend leaving your settings as they are until you've had a chance to try the new software and see if it's right for you. If you're satisfied with its performance, you can make it your go-to program for PDFs by right-clicking one and selecting 'Open with'. Browse to the EXE file for your new PDF reader, check 'Always use the selected program to open this kind of file', then click 'OK'.

Most programs will also ask you to install their corresponding browser extensions. Again, we recommend skipping this until you've had a chance to get used to the new software. You can always install the extensions through your browser's store at a later date.

Foxit Reader

Foxit Reader is perhaps the best known alternative to Adobe Reader, and it's easy to see why. Its ribbon-based interface takes inspiration from Microsoft Office, so you'll instinctively know where to find its impressive array of tools.

Download Foxit Reader free

Top download - Foxit PDF ReaderThe tabbed interface makes it easy to work with multiple PDFs at the same time, and there are some nice extra touches such as form filling and PDF annotation.

The ubiquity of the PDF format makes it a popular target for malware and virus developers, so Foxit Reader offers a Safe Reading mode that provides control over things such as internal links and Javascript integration.

Download Foxit Reader freeDownloadable add-ons are available to convert PDFs to other formats (and vice versa) and to combine multiple PDFs into a single file. File conversion is incredibly simple thanks to the inclusion of an entry in Windows' context menu.

It's very easy to see why Foxit Reader is so popular. Read on to discover four more of our recommended PDF readers. Have we missed your favorite? Let us know in the comments below.

Nitro Reader

Like Foxit Reader, Nitro Reader bears more than a passing resemblance to Microsoft Office -- and this is no bad thing. Right from the start this feels like a highly accomplished piece of software and there are plenty of document viewing options to choose from.

Download Nitro Reader free

But this is a program that's about more than just viewing. As well as including an annotation and highlighting option, Nitro PDF also lets you add sticky notes to the documents you open.

Download Nitro PDF freeIf you need to create PDFs from other documents, this can be one with Nitro PDF, and it is also possible to convert in the opposite direction -- PDF to text, for example. You can also extract all of the images from a PDFs in one fell swoop, digitally sign electronic documents with an e-signature. This is without doubt one of the most polished PDF tools out there, and it would be easy to forget that it is completely free of charge.

PDF-XChange Editor

PDF-XChange Editor replaces the now discontinued PDF-XChange Viewer, and it is available as both a portable app and a regular installable program.

Download PDF-XChange Editor free

The free edition contains handy features such as tracked comments, the ability to insert or extract pages, and digital signing, but those marked 'Pro' in the menu are only available in the paid-for version. The free edition's killer feature is OCR. You can scan printed documents, have the text converted into searchable format, and save the resulting document as a PDF.

Download PDF-XChange Editor freeDuring installation, we recommend selecting the 'Custom' option rather than 'Complete', then deselect the components you don't want to install. They are presented as an expandable tree, so make sure you click all the '+' icons to discover what's hidden there.

Slim PDF Reader

Slim PDF Reader is by far the smallest download in this roundup, occupying just 1.43MB of space, and makes a virtue of its frill-free approach.

Download Slim PDF Reader free

This really is little more than a viewer, but that's no bad thing. Controls and navigations are simple and self-explanatory, and the program benefits from being lightning-fast.

Download Slim PDF Reader freeSearch, print and rotate are the most advanced features you'll find, although you are invited to try a free trial of the PDF to Office converter.

If you're looking for a PDF reader without the bloat, this could be the ideal choice. The only real drawback is the inability to view two pages side-by-side as a spread.

Icecream Ebook Reader

As the name suggests, Icecream Ebook Reader is designed primarily for viewing EPUB and MOBI documents, but it doubles as a simple PDF reader.

Download Icecream Ebook Reader free

As this is an ebook reader, you are encouraged to organise all of your books into a library, sortable by type and fully searchable -- but there's nothing to stop you from just opening individual PDFs.

Download Icecream Ebook Reader freeThe program has a slightly unusual look, but it is a joy to use. Navigation of PDFs is wonderfully simple, and there are a number of viewing modes to choose from, including an eye-friendly night mode. You can quickly add bookmarks and create notes, which are accessed through the fly-out Contents pane.

If you have a Word document or ebook that you'd to convert to PDF format, or vice versa, you might like Icecream PDF Converter, from the same developer.

Software : Round up: Best free parental control software 2016

Software : Round up: Best free parental control software 2016


Round up: Best free parental control software 2016

Round up: Best free parental control software 2016

Introduction

It's hard to imagine anything less child-friendly than an uncensored internet. A rabid wolf, maybe, or a playground floored with broken glass and razor wire. The more connected we become the more we need everybody online - and that means trying to ensure that our children aren't exposed to the very worst content, ideas and behaviour that exist online.

Software can't do everything, of course, but it can help to make parents' lives much easier. These are our picks of the best parental control software in 2016.

Qustodio

Most parental control software is aimed at Windows, but Qustodio (think 'custodian') is also available for OS X, Android, iOS, Kindle and Nook.

Download Qustodio free

Download Qustodio freeThe free version is limited to one user and one device, but if you want to control multiple devices the paid-for version isn't too steep at US$44.95/£29.95 (about AU$61) per year for up to five devices (higher-end plans are available for larger families).

The free version covers the basics, enabling you to set rules and time schedules, block pornography and other unsuitable content; if you go for the paid-for version that adds SMS monitoring, social media features and per-app controls. But even the free version is one of the most comprehensive parental control apps around.

Download Qustodio freeIts raft of features and support for a wide range of platforms make Qustodio our top recommended parental control software, but there are many other excellent free programs available, some of which may be better suited to your individual needs.Read on for more of the best tools to keep your kids safe online.

FamilyShield

FamilyShield is a free service from OpenDNS. It automatically blocks domains that OpenDNS has flagged under the headings "tasteless, proxy/anonymizer, sexuality, or pornography".

Download FamilyShield free

Download FamilyShield freeOne of the big pluses here is that while FamilyShield can run on PCs and mobile devices, you can also apply it to your network router and filter all the traffic that passes through it - it's just a matter of changing the DNS server numbers in your control panel, and that has the happy benefit of improving DNS lookup speeds on some ISPs. By filtering everything at the router level, every device on your network benefits from the filters.

Norton Family

Its creators would really like you to subscribe to the paid-for Premier version, but the free edition of Norton Family is an excellent tool to support you in protecting your kids online.

Download Norton Family free

You can block inappropriate web content and monitor the kids' online activities, see what they've been searching for and how often they've been on Facebook (and whether they're using a fake name or age), ensure they don't accidentally give out personal information and lock down your internet connection at specific times.

Download Norton Family freeThe Premier version adds video supervision, location tracking, Android app and SMS use and time-locks for Android apps. That's US$49.99, £29.99 (about AU$61) per year.

Kidlogger

We're in two minds about using logging software for children and teenagers: tracking every single keystroke, SMS, photo, instant message, Skype call and location feels like an invasion of privacy, but we can see the benefit for parents who suspect their child may be keeping something important private, such as online bullying or grooming.

Download Kidlogger free

Download Kidlogger freeThe free version of Kidlogger tracks one device and keeps logs for nine days. Upgrading to the premium package for US$29 (about £19.72, AU$40.20) per year lets you monitor five devices, with log history stored for 30 days.

The service is available for Windows, Mac and Android, and there's a separate app for non-jailbroken iPhones and iPads.

Spyrix Free Keylogger

Keyloggers have something of a bad reputation online, as they're often used by villains, but they can be a force for good too, and Spyrix's features enable you to see what your children have been up to.

Download Spyrix Free Keylogger free

Download Kidlogger freeAlthough it's dubbed parental control software, it's really a monitoring program; it doesn't stop the kids getting up to no good, but it does let you see exactly what they've done. That means it isn't really appropriate for younger children's computers, but it may be appropriate for older children if you suspect online bullying or other unpleasantness.

WebFilter Pro

Download WebFilter Pro free

WebFilter Pro is a cloud-based add-on for Chrome and Firefox that adds filters to web browsing. It can block malware, adult content including drug, guns and other inappropriate content, proxy servers, known spam sources, social networks and media streaming sites.

Download WebFilter Pro freeYou can add your own sites to the blocklist and to the whitelist, but there's a fairly big Achilles Heel here: while there's password protection to stop the kids from overriding your settings, there's nothing to stop them from simply disabling or uninstalling the extension altogether. That means the add-on does a decent job, but it's not one for older children.

Windows Live Family Safety

Family Safety is bundled into Windows 8 and 10, but if you're running an older version of Windows you can download it via Windows Essentials.

Download Windows Live Family Safety

The app offers a range of parental controls including restricting web browsers to specific sites or specific kinds of content; tracking your kids' activities and enabling you to see what websites they've visited

Download Windows Live Family Safety FreeYou can also lock down search engines so they don't return inappropriate results, and limit what can be done at specific times - handy if you're trying to ensure your kids aren't spending every waking hour in multiplayer gaming or social media. It's particularly good if you use Microsoft's Internet Explorer or Edge browsers.

Zoodles Kid Mode

The problem with many parental control apps is that they're most effective for older children: while filtering adult content and other unpleasantness is obviously a good thing, there's plenty of stuff that isn't adult that can still scare younger children silly.

Download Zoodles Kid Mode free

Zoodles Kid Mode addresses that by combining filtered browsing and a dedicated web browser to create a walled garden: everything in it is safe for kids and there's no risk of anything awful popping up.

Download Zoodles Kid Mode freeIn addition to Windows, Zoodles Kid Mode is also available for Macs, Android and iOS, and a brand new version is currently in development.

K9 Web Protection

Available for PC, Mac, iOS and Android (but not updated in some time: the most recent release notes date from 2014)), K9 Web Protection's features include blocking of 70 different website categories (including illegal drugs, dating and racism), time restrictions, mandatory SafeSearch in Google, detection of new and malicious adult websites and custom block/allow lists.

Download K9 Web Protection free

Download K9 Kid Protection nowIt doesn't cover chat programs, we wouldn't rely on its ageing database to block malware and there aren't options for multiple users (for example, you can't have different settings for a teenager and for a younger child) but K9 is impressively difficult to disable or remove, and it's good at what it does.

FoxFilter

There are plenty of browser add-ons that offer parental control, but there's a big flaw in each and every one of them: if your child downloads or sideloads a different browser, they're useless.

Download FoxFilter free

That means filters such as FoxFilter are useful only for children who won't do that, or for environments where the filtering is just extra insurance for children who are usually within sight and sound of the grown-ups.

Download FoxFilter nowIn such cases it's simple and effective, with good blocking of suspicious content and the ability to fine-tune the filter so it doesn't block innocent content. It's now also available for Google Chrome.

Other tools to consider

Kindergate Parental Control - Designed for schools as well as home users, Kindergate includes ad-blocking, content filtering (using real-time analysis, not just a database of known sites) and activity logging.

Kaspersky Safe Kids - Available for Windows PCs and Android devices. In addition to content filtering and social media monitoring, it can track your kids' location using their phone's GPS.

Refog Personal Monitor - Refog is designed to be unobtrusive, running quietly in the background while you monitor your kids' activity remotely. Much more than just a keylogger, it can also record voice chats, monitor visited websites and games, and capture screen grabs.
