Interval Timer Studio

Interval Timer Studio makes clean, distraction-free workout timers you can just press play and follow — no coaching, no talking, no ads mid-set.
Clear audio cues for work, rest, and a 3-second warning mean you never have to look at the screen. Distinct tones let you train with earbuds in and the phone in your pocket.
Formats we cover:

Tabata (20/10) and HIIT (30/30, 45/15)
EMOM — every minute on the minute
Boxing round timers with a real bell
Circuit training (6 and 8 station)
Yoga flow and plank holds
Running intervals with warm-up and cool-down

Pick your duration, press play, and go. Loop any video for a longer session.
For general fitness use only — not medical advice. Consult a doctor before starting any exercise programme, especially with pre-existing conditions. Use at your own discretion.
New timers added regularly. Subscribe so the right one is ready when you are.
