Watch, Health and widgets

Apple Health, widgets and reminders

Opted-in signals in, rich workouts out, and nudges that learn when you train.

With your permission, Mettle reads body and recovery signals from Health and writes rich Watch workouts back to it. Heart rate and measured rep tempo can extend recovery and refine the next set or session.

Reminders that learn you

On the device, Mettle learns roughly when you train on each weekday and nudges you then, with supportive notes on rest days. The wording is generated by Apple Intelligence and tuned to your level, with a deterministic fallback, and it never invents a statistic about you.

Home Screen and Lock Screen widgets, Live Activities during a session, Siri and Shortcuts, and Spotlight indexing are all included and all free.
