Cadence is a HIIT interval timer for iPhone, iPad, and Apple Watch built on one promise: nothing interrupts your workout. No ads, no account — and no paywall can ever appear while a timer runs (a rule enforced by unit-tested code). Full-screen color-coded phases readable from across the room, voice coach, haptics, Live Activities, and a standalone Watch app with live heart rate. New workouts drop weekly. Pay once for lifetime (Family Sharing included), subscribe, or stay free. In 6 languages.

Hey Product Hunt! 👋 I built Cadence because every interval timer I tried interrupted my workout — an ad between rounds, a paywall mid-Tabata, a timer I couldn't read from the floor. So Cadence has one rule, enforced by unit-tested code: nothing can interrupt a running timer. No ads ever, no account, no popup between rounds. What's in it: • Full-screen, color-coded phases you can read mid-burpee from across the room • Voice coach ("Last round", "Halfway") + haptics so you never look at the screen • Standalone Apple Watch app with live heart rate — leave your phone in the locker • Live Activities + Dynamic Island on iPhone, big grids on iPad • Tabata, EMOM, AMRAP, boxing, run/walk presets + a new workout drop every week • Pay once for lifetime (Family Sharing included) — or don't; the free tier keeps the full timer engine, no time limit Out now in English, German, French, Spanish, Portuguese, and Japanese. I'd love your feedback — and I've got promo codes for anyone who wants to try Pro. What would you want in an interval timer?

Honestly the no-ads-during-workout rule is a really nice touch, and being able to glance at my watch for heart rate without grabbing my phone makes the whole thing feel way less clunky.
