Store description excerpt

BattAI • BattAI uses five values from public iOS APIs: battery level, charge state, Low Power Mode, whole-device thermal state, and time. Other results are calculated from those readings or added by you. Each detail shows its source and limits. • BattAI has no account, telemetry, ads, or network requests. Data stays on this device, except for a minimal feature-limited snapshot sent directly to your paired Apple Watch. Sampling is limited, analysis runs at most every five minutes, estimates use ranges, and missing data stays missing. Health • Battery health score • What shapes the score • Maximum capacity over time • Estimated time to 80% Charging • Charge care • Charge range • Charge rate Reports • Create a clear battery report for service, resale, or your own records. • Full report: the app's charts and text • The same report saved as a PNG • All of your data as a plain-text table Privacy • No ads, analytics, tracking, third-party SDKs, or internet requests. Data stays here, except for a minimal snapshot sent directly to your paired Apple Watch. • Public iOS APIs provide battery level, charge state, Low Power Mode, whole-device thermal state, and time. BattAI labels every other result as estimated or provided by you. • The fixed rules follow established lithium-ion guidance on deep discharge, long periods at high charge, heat, and charge volume. Apple’s 80% maximum-capacity service benchmark is kept separate from BattAI coaching bands. No result promises extra battery life. Understand your battery over time • One payment. Lifetime access. No subscription. • Your purchase is tied to your Apple Account and works on your devices.
