OpenTrainer: Workout Tracker

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.
