What is Workout Timer?

Workout Timer lets you build interval training sessions with adjustable work and rest periods. Set round durations for exercises, breaks, and cool-downs. Works well for HIIT, circuits, or any timed routine.

Configure prep, work, and rest seconds independently, then set the number of rounds. The screen colour switches between orange for work and a calmer tone for rest, with audio beeps in the last three seconds of each phase so you don't have to keep watching the clock. The total session time updates live as you tweak settings.

How to use

1. Set your work interval duration (e.g., 30 seconds) and rest interval duration (e.g., 10 seconds).
2. Choose the number of rounds you want to complete, then add an optional warm-up and cool-down for a low-intensity ramp before and after the main work.
3. Press Start to begin. Audio cues and color changes signal each interval switch.

When to use

• Running a Tabata block: 20 seconds work, 10 seconds rest, eight rounds.
• Counting EMOM rounds where each minute starts a fresh exercise at the bell.
• Pacing a kettlebell or dumbbell circuit at home without a stopwatch.

Result

A typical HIIT session: 30s work / 15s rest x 8 rounds with 10s prep countdown. Total workout time: 6 minutes 10 seconds.

FAQ

Will the timer keep counting if I switch tabs or lock my phone?

Yes on desktop. On mobile, background timers can be throttled by the system, so the count may drift if the screen sleeps. Keep the tab in the foreground and consider disabling auto-lock for the session.

Does it play sound, and can I run it silently?

Yes — there are short beeps in the final three seconds of each phase. To go silent, mute the tab (right-click the tab and choose mute). The visual phase change still tells you when work ends and rest begins.

Are there preset workouts so I don't have to type the numbers every time?

Yes. Five quick presets cover the most common formats: HIIT (30/15 x 8), Tabata (20/10 x 8), EMOM (50/10 x 10), Strength Circuit (90/30 x 5 with a 2-minute warm-up), and Beginner HIIT (45/15 x 6 with shorter ramps). Tap one to load it, then tweak the numbers if you want a slight variation.

How do I add a warm-up and cool-down?

The Warm-up and Cool-down fields are separate from Prep Time. Set Warm-up to a low-intensity ramp (60–180 seconds is typical) and Cool-down to a stretch or active recovery block. Both run automatically — warm-up plays once before the first work round, cool-down once after the last.

Can I save my routine so I don't reconfigure it every time?

Yes. Configure the four numbers (plus warm-up and cool-down if you want them), enter a short name in the Saved Routines panel, and hit Save. The routine sits at the top of the list and one tap restores every field. Up to twenty routines are kept locally on your device.
