The Wikimedia Commons Android app allows users to upload pictures from their Android phone/tablet to Wikimedia Commons. Download the app here, or view our website.
Initially started by the Wikimedia Foundation, this app is now maintained by volunteers. Anyone is welcome to improve it, just choose among the open issues and send us a pull request :-)
We are currently applying for an IEG renewal to work on the app for the next 6 months. Feedback is very much welcomed.
We try to have an extensive documentation at our wiki here at Github:
