The iOS version has a flow chart, HD art, high quality music, and an additional minor ending called the syringe ending. However, it has no character animations, no voice beeps (the DS version has different tones of voice beeps to make it seem like the characters have voices), and no escape rooms, which were replaced with summarizing visual novel sections.
