Most fitness apps are built around social feeds and rigid coaching systems. GymJC is built as a flexible training tool you control.
GymJC is a training tool, not a coaching platform or social network.
It's designed for people who want structure without noise — and full control over their training data.
No account. No social feed. Workouts sync through your own iCloud and stay yours.
Stay focused with lock screen and Dynamic Island updates during your workout.
Sync workouts and import body measurements and heart rate via Apple Health.
Unlimited workout logging, interval timers, templates, and more — all free.
