BattAI: Battery health score
Battery checks and alerts, no account, no cloud
BattAI estimates your iPhone battery’s condition and alerts you when it’s full (80/90/100%), low (10/20/30%) or overheating — alerts work even with the app closed. It also shows maximum capacity over time, an estimate of when capacity may drop to 80%, plus charge range and charge rate guidance.
Per the description, the app reads five values from public iOS APIs (battery level, charge state, Low Power Mode, device thermal state, time); everything else is calculated or entered by you and labelled as such. No account, no analytics, no network requests; data stays on the device apart from a minimal snapshot sent to a paired Apple Watch. Reports can be produced as charts and text, as a PNG, and as a plain-text table of all your data — useful for service or resale.
Why no subscription? Every feature is free for 24 hours; afterwards alerts and the live battery level remain. The rest is a one-time $5.99 (Lifetime Pro), tied to your Apple Account.
