🧐 FAQ

Does it work in the background? Keep this tab open and visible for the best experience. Mobile browsers often throttle background tabs to save battery, which can desync the timer.

Why can't I hear the audio? Check your device's mute switch and volume. Note: Most browsers require you to click "Start" before they allow the site to play sound.

Is my workout data private? Yes. Your presets are stored locally on your device. We never send your data to a server.

📚 The Science of Tabata

Developed by Professor Izumi Tabata for Olympic speed skaters, the Tabata Protocol isn't just about the 20/10 split—it’s about maximum intensity. A true 4-minute Tabata session is scientifically proven to improve both aerobic and anaerobic capacity more effectively than traditional steady-state cardio. If it feels easy, you aren't doing it right!
