List of free and open-source iOS applications

Source: Wikipedia, the free encyclopedia.

This is an incomplete list of notable applications (apps) that run on iOS where source code is available under a free software/open-source software license. Note however that much of this software is dual-licensed for non-free distribution via the iOS app store; for example, GPL licenses are not compatible with the app store.
