Common questions

Does it need internet? No. It works offline.

Does it drain my battery? It is designed to be light. If you see something unusual, send us the diagnostics report.

Which iPhones does it run on? iPhones with iOS 26 or later, which includes the iPhone 11 and newer, and the iPhone SE (2nd and 3rd generation). It is iPhone only for now.
