Forty-five seconds on, fifteen off, eighteen rounds, and a ten-second countdown before the first one. Interval Timer runs the clock so you can run the workout: it counts down prep, work and rest, ticks through the last three seconds of every phase, keeps the screen awake, and keeps going when the phone is locked or in your pocket.
Set four numbers and press Start. Name the routine and save it, and tomorrow it is one tap away. No account, no feed, nothing to scroll past: just the timer, the current set and a ring that shows how much of this phase is left.
WHY YOU'LL LOVE INTERVAL TIMER
• Four values, any workout: Preparation from 0 to 60 seconds, Work and Rest from a few seconds to 24 hours in minutes and seconds, 1 to 100 Sets.
• Start, Pause, Resume and Stop, a Current set counter and a progress ring for the phase you are in.
• Audio cues you can train by: one tick at 3, 2 and 1 seconds, a different tick at the switch, so you never look at the screen. Turn Sound off in Settings for a silent session.
• Keeps running in the background: lock the phone, open another app or answer a message, and the countdown and the ticks continue. Audio from other apps keeps playing too.
• The screen stays awake while the timer is in front of you.
• Save your timers: name them (up to 50 characters), find them with Search in Saved, edit or delete them, and load one with a tap.
• Change opens the current timer for editing without touching the saved ones.
• Big digits and haptic feedback on every button, readable from the floor and across the gym.
• Useful Content: articles on productivity, time management, routines and the Pomodoro technique.
• Works offline, no account, light and dark themes, 73 languages.
HOW IT WORKS
1. Set Preparation, Work, Rest and Sets, or pick a timer from Saved.
2. Tap Start. The ring and the Current set counter follow the phase and the round.
3. Listen for the ticks: three for the countdown, one for the switch. Pause, resume or stop whenever you need to.
PERFECT FOR
• HIIT and Tabata: 20 seconds on, 10 off, 8 sets, done.
• Boxing and martial-arts rounds, circuit training, bootcamps and CrossFit-style sessions.
• Running sprints, stretching, mobility and breathing exercises.
• Focused work: 25 minutes on, 5 off, as many sets as the afternoon needs.
TIPS FROM THE GYM
• EMOM-style: set Work to 1:00, Rest to 0 and Sets to the number of minutes you want to train.
• Tabata: 20 seconds Work, 10 seconds Rest, 8 Sets, and 10 seconds of Preparation to get into position.
• Save one timer per workout type and name it by the session, so Saved reads like your week.
• Long rest between heavy lifts? Set Work to the lift time, Rest to 3:00, and let the ticks call you back to the bar.
BUILT FOR THE MIDDLE OF A SET
Sweat, gloves, a phone on the floor two meters away: the timer is designed for that moment. Digits fill the screen, the ring shows the phase at a glance, and the ticks tell you when to go and when to breathe. Nothing pops up, nothing asks for a tap, and when the last set ends, it simply stops.
YOUR DATA STAYS WITH YOU
Nothing is uploaded and no account is needed. Saved timers and settings live on your device, and the timer works without internet.
