Apple Health Strength Training App
Use Apple Health data to make better training choices.
Apple Health already has useful recovery signals. Sundee Fundee turns those signals into workouts that match the way you actually feel, not just the plan you made last week.
Helpful inputs
- HRV and resting heart rate
- Sleep stages and sleep consistency
- Activity trends and training load
- Privacy-first on-device health permissions
Why this integration matters
The data is already there. The missing piece is the decision.
Apple Health can surface the signals that matter most for readiness, but the app still needs to decide whether today should be a heavy day, a technique day, or a pull-back day. That is the job Sundee Fundee is built to do.
