About this app

A workout timer for anything that alternates work and rest: Tabata, HIIT, circuit training, boxing rounds. Set it up once and the sounds and vibration tell you what comes next, so you can keep your eyes off the screen.

■ How it works
• Choose prep, work and rest times (seconds) and the number of rounds, then tap Start. The total workout time is shown before you begin.
• Built-in presets: Tabata 20/10 ×8, HIIT 40/20 ×10, Boxing 3:00/1:00 ×12
• Save your favorite setups as named routines, and edit or delete them later.

■ During the workout
• A large countdown, with the screen color changing by phase (prep yellow, work green, rest blue), easy to read from across the room.
• Current round, next phase and total time left are shown together.
• Pause, resume, skip and reset. Pressing Back by accident asks before ending the workout.
• The screen stays on while you train.

■ Sounds and vibration
• Short beeps count down the last 3 seconds before each phase change.
• Work start, rest start and finish each have their own sound. Your music keeps playing.
• One buzz when work starts, two when rest starts (when touch vibration is on in your device settings).
• Turn sounds or vibration off separately in Settings.

■ History
• Completed workouts are saved by date, so you can see the last 7 days at a glance.

■ Good to know
• The timer stays accurate while the app is open on screen. Keep it open while you work out.
• No sign-up. Settings, routines and history stay on this device.
• A banner ad sits at the bottom of the screen, and a full-screen ad may appear when you return to the start screen after finishing a workout. Full-screen ads never appear during a workout. A one-time purchase in Settings removes all ads.
• Available in 18 languages.
Set work, rest and rounds once, then let beeps and vibration guide every phase
