Battery Life & Usage Monitor

See how your battery behaves over time. Clear views show the current state, recent history, usage patterns, best/likely/worst forecasts, and whether actual drain is faster or slower than expected. Widgets keep essential readings visible on iPhone, iPad, and Apple Watch. Each device builds its own history from local battery readings. No account, ads, or tracking. Background updates are scheduled by the system, so history may not be continuous. Core features and the complete Apple Watch experience remain free. A 72-hour full-experience trial starts automatically on first launch and unlocks advanced views and widgets. It ends without a charge and does not renew. Lifetime Access is a separate one-time in-app purchase; there is no subscription.
