Hi,
last week we have released a new version of Kiwix for Android which includes a few new features. Most of them were coded by young students participating to the Google Code-in program:
* New "share with friends" button * New "fullscreen" feature * New 'back to top" button * Better search suggestions * Small UI fixes
Enjoy: https://play.google.com/store/apps/details?id=org.kiwix.kiwixmobile
