Interval Timer by STRNTH

Interval Timer by STRNTH is a free interval timer for HIIT, Tabata, EMOM, AMRAP, boxing rounds, running intervals, stretching and more. Build any timer you want with no fixed structure, then run it hands-free and read it from across the room. BUILD ANY TIMER - Add as many steps as you like, each with its own label, duration, colour, sound and voice. - Group steps into repeat blocks so a round loops as many times as you need. - Link separate timers together to chain a warm-up, workout and cool-down into one session. - Start from a template: Couch to 5K, Tabata, HIIT, 7 minute workout, EMOM, AMRAP, boxing rounds, Pomodoro, box breathing and full body stretch. RUN IT HANDS-FREE - A giant readout inside a progress ring, sized to read from across the gym. - Full-screen colour per step so you know your phase at a glance. - Voice reads each step and announces what is next before it arrives. - Sound cues on the last three seconds, plus beep, go, switch, rest, bell, horn, gong and whistle tones. Import your own sounds too. - Optional spoken 3-2-1 countdown, a cadence metronome from 60 to 180 BPM and haptic feedback. - An optional get-ready countdown before you start, from 3 to 30 seconds. - Choose what the screen shows: interval time, total time, interval count, the clock or heart rate. MORE TOOLS - A countdown tab with saved presets for a fast single timer. - A stopwatch with laps that highlight your fastest and slowest split. - Workout history that logs every session so you can look back and run any timer again. - Light and dark themes and your own custom step colours. - Share a timer as a link or a file, and import timers others send you.
