IntertaktInterval timer for HIIT, Tabata, and rounds. Voice and beep cues over your music; the screen stays off the whole way.
About Intertakt
Intertakt is an interval timer for HIIT, Tabata, and round-based training, built for people who train to their own music and do not want to manage a phone between efforts. The problem it addresses: mid-effort is the wrong moment to read a display. Intertakt makes every round boundary audible instead — countdown beeps and a spoken cue over your own playlist, each channel with its own volume, so the playlist plays straight through and nothing has to be watched. Sessions run with the screen off and the phone wherever it lands. Incoming calls and app switches do not end the round: the session resumes at the exact second it stopped. The free tier is unlimited — 0 ads, unlimited sessions, 0 accounts. Premium is a one-time purchase, not a subscription, adding unlimited custom plans, session history, and JSON export. Built with Flutter, offline-first, in English and Russian. Coming soon to Google Play; the waitlist is open at intertakt.com.
