Fast workout & routine log
Only for iPhone
Free · Designed for iPhone. Not verified for macOS.
iPhone
OpenTrainer is a workout tracker that respects your time. Log sets in two taps — not five screens.
TRACK
One-thumb set logging with smart weight and rep steppers, warm-up flags, RPE, cardio and mobility entries. Rest timers with live countdown, haptics, and lock-screen alerts so you never miss the start of your next set.
PLAN
Build routines by hand with drag-and-drop days, import them as JSON, or generate a personalized plan with AI based on your goals and the equipment you actually have — describe your gym in plain words and OpenTrainer figures out the rest.
UNDERSTAND
The Training Lab analyzes your week: volume by muscle group, effort trends, recovery signals, personal records, and a body map showing what you've hit and what you haven't.
YOUR DATA STAYS YOURS
Full JSON export and in-app account deletion. Free while in alpha.
Ratings & Reviews
Fixes and quality-of-life from our first week:
- Workout cards in History respond to taps again
- The app stays out of the keyboard's way: inputs, search results, and the rest of the page stay reachable while typing
- Weight and reps entry starts empty with your last value shown, so changing weight mid-set takes no deleting
- Effort (RPE) carries forward between sets
- Exercises added mid-workout join the end of your list, not the top
- Edit your custom exercises from the exercise picker
- Groundwork for over-the-air fixes, so small repairs reach you between App Store releases
