Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Added a rest timer on Apple Watch: quick start 60/90/120s, pause/resume, add time (+10s) and stop. Haptics at 10 seconds remaining and at the end of the rest. Optional notifications so you’re alerted even when the app is in the background or the screen turns off. Improved usability to validate sets and start rests more easily.
