What it does
Routines that don’t fight you
Build push, pull and legs, 5×5 or whatever you run once, then start it with a single tap. Or skip the template and log a free session.
- Reorder exercises by dragging
- Several routines, switch any time
Log sets without thinking
Weight and reps fill in from your last session. Confirm or adjust, and the rest timer starts on its own.
- Autofill from the previous session
- Rest timer with notifications
Records you don’t have to notice
Stark marks every personal record as you log it, and charts weight, reps and volume for each exercise.
- Detected on every set
- Notes per exercise for form cues
No more plate math
Enter a target weight and Stark shows which plates go on each side. Plates taken? Leave them out and it finds another way.
- Your own plate inventory
- Olympic, EZ and dumbbell bars
