A rest timer you never have to start
Log a set and the rest starts on its own. Lock your phone and the countdown keeps going on the lock screen, with your next set and the plates to load.
On your lock screen, not in your way
On Android, Liftsmith shows an ongoing notification with the countdown, the next set, the plates, your heart rate and the workout's progress, with Log set and +30 s buttons. On Android 16 it's a Live Update with the time left in the status bar chip.
On iPhone it's a Live Activity on the lock screen and in the Dynamic Island, with the same countdown, next set and buttons. When rest is over you get a chime and a buzz, even with the phone in your pocket.
The right rest for each set
Heavy compound lifts get longer rest than small isolation work, and you can set your own rest for any exercise. Short on time? Take less, and the plan knows. See how long to rest between sets.
- +30 s from the lock screen when you need a bit more
- A polite screen reader announcement at the start, at ten seconds left and at the end
- On your wrist too, with the Wear OS and Apple Watch apps
