Jimzo: Gym Workout Log

Log a set in one tap, rest with a timer that keeps running when your iPhone is locked, and watch your strength grow. No account, works offline.

Jimzo is a fast, simple gym log. Pick an exercise, log your set, rest, repeat. Your workouts stay on your iPhone.

LOG FAST • Log a set in one tap: reps and weight start from your last set. • See what you did last time and the record to beat, right on the set. • A suggestion for the next step: one more rep, more weight, or a deload after a plateau. • Optional warm-up sets and reps in reserve (RIR) for each set. • Reps, assisted reps, holds in seconds, and cardio time and distance.

REST TIMER • Starts after each logged set, with a rest time per exercise. • Alerts you with a sound and a vibration when the rest ends, even with your iPhone locked. • Follow the rest and skip or extend it from the Lock Screen and the Dynamic Island.

SEE YOUR PROGRESS • A weekly goal and the weeks in a row that meet it. • A 12-week calendar of your workouts and records. • Weekly volume, sets, and reps, and the sets each muscle gets. • Estimated one-rep max (1RM) and records for every exercise, computed from your sets. • Repeat a past workout in one tap.

120+ ILLUSTRATED EXERCISES Barbell, dumbbells, machines, cables, bodyweight, and cardio, each with its illustration.

PRIVATE BY DESIGN • No account, no ads, no analytics. • Works fully offline, in the gym basement too. • Your data stays on your iPhone. Export a backup file whenever you want.

APPLE HEALTH With your permission, Jimzo saves each finished workout to Apple Health and runs a Health workout session while you train, so the rest timer keeps running when your iPhone is locked. Jimzo only writes workouts; it reads nothing from Health.
