Intertakt

An interval timer for HIIT, Tabata and rounds that works like a song contest final: the structure arrives as a voice over the music. The presenter's mic sits on top of the mix — a clear voice and countdown beeps play over whatever playlist is already running, each at its own volume, with optional ducking — so every phase change reaches you without a glance. And no glance is needed. Set your intervals once, tap start, put the phone face-down: the session keeps running with the screen off, on Do Not Disturb, in your pocket. A phone call mid-set doesn't send the night back to the opening act — the session survives calls and app switches and resumes from the exact second where it stopped. The free tier is unlimited: 0 ads, infinite sessions, 0 accounts. Premium is a one-time purchase, not a subscription — custom plans, history, JSON export. Built with Flutter, offline-first, in English and Russian. Coming soon to Google Play
