The Commons mobile app was released in 2013 by the mobile apps team of the Wikimedia Foundation. It was available for Android and iOS but has not been maintained in a while and will likely not see further development, thus it has been removed from Play Market and App Store.
Identifying mobile uploads
Mobile uploads will use the template Template:Uploaded from Mobile which will add categories such as:
- Commons:Mobile app/deletion request tracking (Archives of that list can be found here: 1, 2, 3, 4, 5)
You can also use the Mobile Reportcard to track upload statistics.
