Rest like you mean it.
Tap a preset, get a big countdown, and a beep and buzz the second rest is up — so you hit your next set on time, every time.

A simple between-sets timer that runs in your browser — nothing is stored or sent. The beep needs one tap to start (browsers require it), and the buzz works on phones that support vibration. General fitness information, not medical advice; consult a professional before starting a program.
Spotter starts this rest timer automatically the second you log a set — and builds your whole adaptive program around it.
