Tabata's interface and workout system have been updated. Start one of five preset workouts with a single tap: Classic Tabata, Beginner, and three different HIIT options. You can also set your own work, rest, and round values, then save up to eight custom workouts on your device. No account is required; everything is stored only in your browser. The work, rest, and round controls are now more compact. Volume can be adjusted across four levels, with the percentage shown on screen, and the full-screen button is now easier to reach. Choose a preset, create your own workout, and let Tabata keep the rhythm.
