Tabata Timer: Intervals

Choose a ready-made interval timer or set preparation, work, rest, rounds, sets and between-set recovery. Save up to 10 custom timers. Large phase digits and distinct colors keep the next interval clear. Generated audio cues mark countdown, work, rest and finish; vibration and a sound check are included. Device volume stays under your control. On Android, the native foreground timer continues with Home or a locked screen, with a current-phase notification and pause/resume controls. Audio-focus loss pauses instead of resetting. Completed workouts appear in a local calendar with counts/minutes for the last 7 or 30 days. Preparation, pauses and unfinished sessions are excluded. No account or cloud journal is required. Optional reminders use selected weekdays and local time. For adults. Presets are editable timing examples, not medical advice or a promise of safe intensity. Choose an effort that suits you. If you have not exercised for some time or have medical conditions or concerns, discuss exercise with a clinician. Stop if you feel pain, dizziness or unwell. After process termination, recovery is paused; missed cues are not replayed and an expired session is not credited. Keep the browser version visible because background/locking can suppress audio. Reminder delivery depends on OS settings.
