Paper tracking is dead in 2026.

You're halfway to the gym, and remember your notebook is on the counter. RepMaxx is in your pocket and already knows your next lift, your last set, and how much stronger you got.

A printed paper exercise tracker sheet with empty rows for date, muscle group, sets, weight and reps.
The iPhone Stopwatch app running mid-set at 2:38, the clock app you swipe over to between sets.

Stop guessing how long to rest.

No more counting minutes in your head, and constantly swiping between apps. RepMaxx has all the optimal rest times built in, and notifies you the moment your next set begins.
