Intertakt

Every martial arts class runs on a spoken count. The instructor calls each technique out loud over the noise of the room, the whole class keeps its eyes on its own form, and nobody has ever paused mid-kick to check a clock. Intertakt runs interval training on the same arrangement. A clear voice announces every HIIT and Tabata interval and the halfway mark; countdown beeps sit over your own playlist, each channel with its own volume, and the phone can lie face-down from the first count to the last — screen off, on Do Not Disturb, in a pocket or face-down on the floor. An incoming call is a bow, not a dismissal: the round resumes from the exact second it stopped. The terms fit in one breath — 0 ads, ∞ sessions, 0 accounts — and the free tier is unlimited. Premium adds unlimited custom plans, history and JSON export, as a one-time purchase rather than a subscription. Built with Flutter, offline-first. Coming soon to Google Play; the waitlist and founding pricing are open at intertakt.com.
