One call for the day.
Last night’s heart rate variability and resting heart rate, compared with your own recent normal, become a single call: ease off, hold your plan, or push.
Calculated on your iPhone, with no AI and no connection needed. Also on your Home Screen, as a widget.
Hold what you planned
Recovery looks good and a hard effort is still close behind. Train, without stacking another strong day.
The score, and the story behind it.
When the week closes you get a score built from recovery and training load, then a written analysis that connects your sleep, workouts and heart data into a few paragraphs worth reading. Monthly reports follow the longer arc.
“Three tennis sessions made up most of the load, while one easy walk, one strength session and a Sunday run filled in the support work.”
Your workouts, records and reports, kept together.
A calendar of every session with the week’s score beside it, your personal bests by sport, and every report you have generated.
No account. Nothing to sign up for.
Your reports, profile and history stay on your iPhone. The daily reading and the scores are calculated on the device and never sent anywhere.
A written report sends a summary of your metrics, with no name or identifier attached, over an encrypted connection to an AI service. That is the only time your health data leaves the phone.
Free to start.
The daily reading, the scores, the calendar and your records are free. The written reports are a subscription, priced in the App Store, with a free trial when you are eligible.
