With Stack Pro, get a target for your next set, skip the plate math and repeat a set from your iPhone Lock Screen without reopening the app.

KEEP YOUR WORKOUT MOVING Log weight and reps with controls made for the time between sets. Your previous session's numbers are prefilled, so you can pick up where you left off. Build routines, add your own exercises and train in pounds or kilograms.

SEE WHAT YOUR WORK IS ADDING UP TO Revisit your workout history, follow strength trends and track personal records. Explore the muscle map to see which muscles your logged sets worked. Your workout log, history, basic trends and muscle map are free.
