Frequently Asked Questions
Q.Which iPhones are supported?
JamJam requires iOS 17 or later. It's built with SwiftUI and modern APIs to deliver the best experience on recent devices.
Q.How does Screentime-based auto detection work?
JamJam uses Apple's Screen Time API to analyze device usage patterns and infer sleep intervals from periods of inactivity. No need to tap a 'start sleep' or 'wake up' button.
Q.How is this different from Apple Health's sleep data?
JamJam imports Apple Health sleep data as its foundation, then adds what Apple Health doesn't offer: sleep debt calculation, routine checklists, and correlation analysis between your habits and sleep quality.
