GymKeeper

Pay once, train forever. GymKeeper is the gym + cardio tracker built for lifters who are sick of subscriptions — full Apple Watch app included, no extra fees, ever.

Log every set, track every run, and watch your progress compound over weeks and months.

STRENGTH TRAINING Build routines with your favourite exercises, log sets with weight and reps, and track personal records automatically. Supersets are supported — link two exercises back to back and GymKeeper handles the flow. A rest timer counts down between sets and surfaces on your Dynamic Island and Lock Screen so you never lose track.

CARDIO Track treadmill, bike, rowing, cross-trainer, stair climber, or custom cardio sessions from your wrist. Live heart rate, calories, and distance stream in real time from Apple Health. Enter your distance after each session and it syncs straight to your phone history.

MIXED ROUTINES Build routines that combine both — warm-up cardio, then your strength block, then a finisher. Everything runs in order inside a single session.

PROGRESS CHARTS

A stacked zone chart in your history shows exactly where you spent your effort. Zone thresholds use your age or a custom max HR you set in your profile.
