IronLog by GymTracker

Track every workout, see exactly which muscles you trained with a visual body heatmap, log nutrition & hydration, and sync with Apple Health.

GymTracker turns your phone into a complete training log — workouts, nutrition, body measurements and recovery, all in one place, stored privately on your device.

WORKOUT TRACKING Log sets, reps and weight for every exercise, track rest timers automatically, and build custom workout plans for quick starts. A persistent notification keeps your active session visible while you train.

EXERCISE CATALOG Browse a full library of machines, free weights and calisthenics exercises, organized by muscle group, with search and filters. Add your own custom equipment and exercises anytime.

VISUAL MUSCLE HEATMAP See exactly which muscles a session actually trained — including indirect work, like the triceps engaged on a chest day — painted on a front-and-back body map that scales from lightly worked to hardest worked.

EQUIPMENT SCANNER (OCR) Point your camera at a machine's nameplate or weight stack to instantly filter the exercise catalog to match — all processed on-device, nothing uploaded.

NUTRITION & HYDRATION Log meals, track calories and macros against your daily targets, and monitor water intake.

BODY MEASUREMENTS & METABOLISM Record weight, height and body circumferences over time, with built-in BMI, BMR and body-fat calculators to track progress.

APPLE HEALTH INTEGRATION Sync heart rate, sleep, steps, distance, calories and other vitals from Apple Health to see your training alongside your broader health picture — read-only, and only what you choose to share.

PRIVACY BY DESIGN All your workout, nutrition and body data is stored locally in your device's own database — never on a company server. Optional backup to your own Google Drive is available if you want it; the developer never has access to your backups. No ads, no third-party trackers, no analytics SDKs.
