Wikipedia Beta for Android
Wikipedia Beta is an Android application that you can install alongside the current version of Wikipedia. You can test new features before they are available to all users, and provide feedback to the Wikimedia Foundation. The app has a customizable Explore feed that displays recommended and constantly updating Wikipedia content on the home screen. It also features a choice of Light, Dark, and Black themes, and text size adjustment for a comfortable reading experience. The app has a voice-integrated search feature, and supports reading in any language-supported Wikipedia. Wikipedia Beta also has a table of contents, reading lists, image gallery, and definitions from Wiktionary. The code is 100% open source, and you can disable the automatic transmission of crash reports.
The Wikimedia Foundation is a nonprofit organization that supports Wikipedia and other Wikimedia projects. The foundation is funded mainly through donations. For more information, please visit their website.
