This is the source code of the iGendyn iPhone app that was on the App Store circa 2010 but hasn't been available for a few years (I no longer maintain a developer account). Due to repeated requests I've made the source code available so people can build it themselves if they need it. I did a quick check that the project builds in a simulator, but note that it is Objective C++ and not Swift, and there are various deprecated method calls. I don't have an up to date iDevice, so provided without further checks. Hope it works for you!
The code was developed by Nick Collins and is released under the quite permissive BSD-3-Clause license.
