I've been working on a smartphone system for Ren'Py and decided to release a free version for developers to use in their own projects.

icePhone OS includes messaging, social media, banking, music, gallery, camera, settings, stats and persistent data. It's built with Ren'Py and Python and can be customized for different types of visual novels and simulation games.

I'm mainly sharing it here to get feedback from other Ren'Py developers and see what features would be useful to add.
