The tour
Your workout log, from your first set to your end goal.
Four moves, for real.
Log a session on a whim or straight from your program. Exercises and sets a tap away. Adjust, confirm.
Confirm a set and the timer starts on its own. Your numbers get analyzed, measured, saved.
The countdown is on your wrist too. Log your set without pulling out your phone.
Every new best, the app keeps it and shows it off. A new bar to beat.
Session done: a quick, simple recap of all your numbers, and your day-to-day progress.
Offline first
A gym tracker that works offline. Really.
Airplane mode, basement gym, dying wifi, or no connection at all: your session saves the same way, and sync kicks in the moment you're back online. A network problem should never keep you from training. That's the whole point of this app.
