The complete workout tracker for iPhone — strength, cardio, and guided mobility, with a rest timer that lives on your Lock Screen. Your data never leaves your device.
How it works
Choose from 42 built-in templates and multi-day programs like Push/Pull/Legs — or build your own.
Weight, reps, done. The rest timer starts itself and follows you to the Lock Screen.
PR badges when you beat your best, weekly volume charts, streaks, and 50+ achievements.
Training hub
Your active program, today's session, weekly goals, and recent history — ready the moment you open the app. No digging through menus.
Set logging
Log weight and reps with a tap. See what you lifted last session, get smart progression hints, and earn gold PR badges when you beat your best.
Rest timer
Your countdown lives on the Lock Screen and Dynamic Island — elapsed time, current exercise, and next set, without unlocking your phone.
