The Wolff Timer vs HIIT Time

BACKGROUND RELIABLE The timer keeps running accurately even when your phone is locked or you're using other apps. Never miss a transition.

Most workout timers bury you in settings before you've done a single burpee. This one doesn't. Pick 10, 20, or 30 minutes. Hit Start. Done. HIIT Time runs classic high-intensity interval training: 30 seconds of work, 15 seconds of rest, repeating until your session is up. The screen turns blue for work and teal for rest, so you can read your phase from across the room mid-exercise. Train differently? Build your own presets for Tabata, EMOM, rounds, or any work and rest combination you use.
