Using the app

Swipe between Overview, Battery History, Tactical Forecast, Divergence, and Model Telemetry. Widgets show a local snapshot from the same device.

Each device builds its own history. The Apple Watch does not copy or replace the iPhone battery history.

Background updates

Apple platforms decide when background work runs. History may contain gaps when the app is not active, the device is in Low Power Mode, or the system delays background refresh.

The app does not claim continuous monitoring or an exact remaining time. Forecasts improve as local observations accumulate.

Trial and Lifetime Access

The free download includes Overview, About & Privacy, the Overview widget, basic full/low battery alerts, and the complete Apple Watch experience.

The full-experience trial starts automatically on first launch and unlocks every advanced iPhone, iPad, and Mac view and widget for exactly 72 hours. It ends without a charge and never renews or converts into a paid product.

Lifetime Access is a separate one-time In-App Purchase. It is not a subscription. With the same Apple Account, the purchase unlocks the native iPhone, iPad, and Mac versions. Open the purchase sheet and choose Restore Purchases after reinstalling or moving to another device.

Troubleshooting

The app says it is learning

Keep using the device normally. Early values are provisional until enough local observations exist.

A widget looks stale

Open the app once, then allow the operating system to refresh the widget timeline.

Mac hardware fields are missing

Cycle, capacity, voltage, and energy fields appear only when the Mac hardware and macOS expose them.

Erase local history

Swipe to About & Privacy, choose Erase Local History, and confirm. This resets local samples, forecast state, and widget snapshots.
