StayFit.

See every muscle you train.

StayFit turns your workouts into something you can actually see. An interactive 3D body map lights up each muscle by how hard you've worked it — so you always know what you're hitting, and what you're neglecting.

FEATURES
• Interactive 3D muscle map that shades muscles by training effort, in real time
• Build custom workout splits — push/pull/legs, upper/lower, or your own routine
• Log sets, reps, and weight in seconds — plus cardio (run, bike, row, and more)
• Per-muscle recovery tracking so you know when each muscle is ready again
• Progress charts for volume, workouts, bodyweight, and cardio
• Apple Health sync for steps, active energy, and weight
• Works fully offline — no account needed, your data stays on your device

WHY STAYFIT
Most fitness apps are just lists of exercises. StayFit is visual. Watching your body respond to your training keeps you consistent and balanced — and makes it obvious when a muscle group is falling behind.

Whether it's your first week in the gym or your tenth year, StayFit gives you a clearer, smarter way to train.
