LoopTimer: HIIT Interval Timer Live

LoopTimer is a standalone interval timer built for Wear OS - no phone required. Set your work and rest intervals, hit start, and let your watch handle the rest. WHY LOOPTIMER Manually tapping your watch between HIIT rounds breaks focus and interrupts your breathing. LoopTimer automates every transition - Work, Rest, and completion - so you can stay fully inside your workout instead of watching the clock. Perfect for HIIT, Tabata, circuit training, weightlifting, yoga, and Pomodoro style focus sessions - anything built on repeating work/rest cycles. KEY FEATURES • Automated transitions - work and rest intervals switch on their own, with a distinct screen color for each phase • Manual skip — double-tap the screen during Work or Rest to jump straight to the next phase, no need to wait out the countdown • Haptic + audio cues - feel and hear every transition, even with the screen off or your wrist turned away • Runs in the background - the timer keeps counting and alerting you while the screen is dark, so you're not stuck staring at your watch • Infinite Mode - loop rounds indefinitely until you stop the session • Smart Recall - LoopTimer remembers your last configuration, so you can start your next session in one tap • Post-session summary - see total elapsed time and completed rounds when you're done • Configurable sets - 1 to 99 rounds, adjustable work and rest durations • No account, no ads, no phone pairing required - it's just a timer on your wrist BUILT FOR THE WRIST, NOT PORTED FROM A PHONE LoopTimer is designed ground-up for Wear OS: large, glanceable text, high-contrast phase colors, and a battery footprint that barely registers during a session.
