Simple Weight vs Interval Timer · HIIT & Yoga

This simple little app uses HealthKit to record your weight on the go. Your weight can be viewed within the Health app or by other HealthKit apps.

Build any interval workout in a minute, or describe it and let AI build it for you — free, no account. Then put your phone down and train — the timer handles the countdowns, the cues, the music, and your history. Boxing rounds, HIIT, Tabata, yoga flows, kettlebell circuits, mobility sessions — one timer runs them all, on iPhone, Apple Watch, Apple TV, and any AirPlay-compatible screen. Live heart rate on the iPhone and on the TV when you cast. One-time purchase. No subscription. No ads. No tracking. $4.99 at launch, $7.99 regular price. Pay once and the app is yours — every feature, every device, forever. Built for everyone who's tired of timers that pause your music between intervals, lock saved routines behind a paywall, or interrupt your workout with full-screen ads you can't close. — BUILD ANY WORKOUT — • Custom routine builder: stack cards of work intervals and rest • Drag to reorder • Large library of exercise icons so every card is recognizable mid-set • Color-coded cards: lime, coral, lavender, peach, mint, sky and more • Built-in gallery of HIIT, Tabata, cardio, mobility, combat, sports, and outdoor routines — clone and customize — DURING THE WORKOUT — • Full-screen live timer with a preview of the next card • Configurable pre-roll "get ready" countdown • Audio cues at halfway, ten-seconds-out, and final three seconds • Per-card cue overrides — silence individual phases without touching the rest • Distinct haptic patterns for each cue — feel timing through gloves or headphones • Keep-screen-awake setting • Pair an Apple Music playlist to a routine — plays, pauses, resumes alongside the timer • HealthKit logging with the right workout type (HIIT, strength, yoga, cycling, and more) — HISTORY & STATS — • Seven-week activity heatmap.
