Aviate's contextual home screen was clever, but if you didn't live in the US, you weren't able to search the web without opening a browser window. Now the app has finally -- perhaps belatedly -- added the feature to the platform to everyone whose addresses don't end in America. If you're not caught up, Aviate is an Android home screen that changes through the day to suit your needs, showing you weather information as you get up and travel tips when you leave for work. Yahoo picked up the company at the start of 2014 and launched it under the name Yahoo Aviate the following June. It's free to download from Google Play, as always, and will work everywhere, oh, except China.
