Intertakt

Intervals kept like a skipping rhyme: a voice calls every round over your music, screen off.

Skipping rhymes solved interval timing long before anyone owned a screen. The chant keeps the count, the rope keeps turning, and the jumper never once looks at a clock — the round is something you hear, not something you read. Intertakt runs HIIT and Tabata on that old arrangement: countdown beeps mark the approach, then a clear voice announces every interval and the halfway mark, mixed over your own playlist with each channel at its own volume. The screen can go dark or the phone can lie face-down on the mat — sessions survive incoming calls and app switches, and a round resumes from the exact second it stopped. 0 ads, unlimited sessions, 0 accounts; Premium is a one-time purchase (custom plans, history, JSON export). Built with Flutter, offline-first, EN+RU. Coming soon to Google Play — waitlist and founding pricing at intertakt.com.
