HIIT Time vs Overtone

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. WHY IT WORKS • Zero setup: three duration options, one button • Audio cues for every phase change, so you never have to look at your phone • Interval cues keep coming when your screen is locked, through notifications and a Lock Screen Live Activity • Haptic feedback on transitions • Full-screen color coding: blue means work, teal means rest • Big, readable countdown built for sweaty, mid-workout glances • Pause, resume, or stop anytime • Elapsed and remaining time always visible • Workout history so you can see what you've put in • Finished workouts save to Apple Health and count toward your activity rings NO NONSENSE • No account.
