SwiftKey Keyboard The most popular keyboard-replacement app on Android made the leap to iOS in time for the launch of iOS 8, with its emphasis on the way it learns your writing style – with Facebook, Twitter and Gmail logins able to give it a head start – to make its predictions even smarter. FireChat FireChat seemed like an innovative novelty when it came out, with the ability to text-chat to people even when internet access was down. But then came the Hong Kong protests, where it proved its mettle as a way to communicate in those kinds of situations, when rival apps struggled. Replay Now billed as a “video editor for Instagram”, that’s selling Replay a bit short, since it’s a slick standalone video editor in its own right too. You can add in up to 200 photos or video clips, then pick styles to turn them into professional-looking videos for sharing on various social networks. Instagram included. Glow Nurture US startup Glow’s first app helped women track their fertility cycles when trying to get pregnant. This year, it followed up with a companion Nurture app for people who succeeded: a pregnancy health tracker providing daily updates, the ability to track all manner of stats, and yes, bump-photo sharing. Star Walk 2 More than 10m people have used the original Star Walk app for some amateur stargazing. This year’s sequel, Star Walk 2, was a good step on. You could use it to identify stars, but now it also had 3D planetary nebulae to browse. Great for stargazers of all ages and experience.
