About this app

Work. Rest. Repeat.

Interval Labs Timer helps you time workouts with clear countdowns, adjustable rounds and alerts. Set up a quick session or save routines for your next workout.

QUICK START
Choose your preparation time, work time, rest time and number of rounds. Rest happens between rounds, with no extra rest at the end.

BUILD YOUR OWN WORKOUT
Combine blocks with different durations and round counts. Set up boxing or Muay Thai rounds, Tabata intervals, HIIT sessions and your own timed routines. Repetition blocks count down at the pace you choose; they do not track movement.

SAVE AND REPEAT
Keep up to 500 routines on your device. Edit, duplicate and start saved workouts, or back them up and transfer them using JSON export and import.

ALERTS YOUR WAY
Choose a beep, gong, low tone, soft chime or a notification or alarm sound from your phone. Adjust alert volume, warning countdown, vibration and optional spoken round or repetition counts. Spoken alerts depend on your phone’s text-to-speech language support.

STAY IN CONTROL
Pause, resume, skip intervals and repeat completed workouts. When notifications are enabled, use the workout countdown and controls from your notification area or lock screen, subject to your Android notification settings.

MAKE IT YOURS
Customize phase backgrounds and timer text colors, or use automatic text contrast. Keep the screen awake if you prefer. Choose English, Turkish, Russian, Spanish, French, German, Italian or Arabic, or follow your device language.

NO ACCOUNT NEEDED
Workouts and settings are stored on your device, and the timer works offline. The app contains ads, which require a connection. Advertising privacy choices are available where required.

Background workouts use an Android foreground service. Some phones require unrestricted battery settings. Force-stopping the app or restarting the phone interrupts the running timer; reopen the app to resume explicitly.
