About Stacco
Stacco is a fast, focused gym log for strength training, with no clutter, no social feed and no ads. Big touch targets make it easy to log sets, reps and weight on the gym floor, and the rest timer follows you to the Lock Screen.
Key Features
Log workouts in seconds
Track sets, reps and weight, add exercises mid-workout without losing your place, and log cardio as well as strength.
Rest timer on your Lock Screen
Start a 1, 3 or 5 minute rest with one tap, or set your own. The countdown and workout clock show on the Lock Screen and in the Dynamic Island.
A weekly plan for your goals
Tell Stacco how often you train and what you’re after, and it recommends a full body, upper/lower or push/pull/legs program. Training days land on the calendar, and Home shows what’s next.
1,300+ exercises with animations
Browse by body part, watch each movement animated, save favorites and create your own.
Routines
Start from presets like Push, Pull and Leg Day, or build your own split and reuse it every week.
Progress you can see
A body weight chart, workout history, a training calendar and streaks show your consistency paying off.
Home Screen widget
See this week’s workouts against your goal, and your last workout, in a small, medium or large widget.
