Intertakt
An interval timer for HIIT and Tabata built like a relay exchange: eyes forward, never on the clock — a voice calls each interval over your music.

About Intertakt
Intertakt times HIIT, Tabata and round-based training the way a relay team runs the exchange zone: the outgoing runner never turns to look — the call comes in over the noise, and the baton has to land inside the zone.
Here the call is a clear voice over your own playlist, with separate volumes for cues and music, so every work and rest interval arrives by ear while the screen stays off or the phone lies face-down.
And the exchange survives the bump: an incoming call or a switch to another app breaks nothing — the round picks up again at the exact second it left.
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. Live on Google Play today; iOS waitlist open — one email when it ships.
