Olli supports the iPhone 5s and the iPhone 6 and 7 family of devices that are running iOS 10.0 or later.
Unfortunately, it will not run on iPhone 5 or iPhone 5c due to technical limitations in those devices.
Olli will run in iPhone emulation mode on iPads that are running iOS 10.0. However, we recommend running Olli on the suggested iPhone devices for optimal fun and experience.
