Since September 2011, as a result of my Google Summer of Code QGIS mobile project, QGIS is available for Android. As the maintainer and main developer behind QGIS for android I’m striving to improve it as much as possible. All my work is done in voluntary base, so if you can, consider supporting the development by using the donate button on the right.
Another great way of helping developing QGIS for android is sponsoring the development of specific features.
