Intertakt

Every boxing gym solved interval timing the same way: one round clock hung high on the wall, and the whole room trains to it. Nobody walks over to read it — the change of round arrives as a sound that carries over bags, music and talk, and each person in their own corner hears it while doing their own work. The clock is shared and unread; the bell does the talking.

Intertakt is that wall unit made personal. It holds your plan — HIIT, Tabata, rounds, EMOM — and calls every change itself: a voice and countdown beeps over your own playlist, each channel at its own volume, so your music keeps playing for the whole session. The phone goes face-down or stays wherever it landed: the timer works with the screen off and never asks to be looked at.

An incoming call or an app switch does not send the room back to round one: the session holds its place and resumes from the exact second it stopped.

The terms stay as plain as the dial on the wall: 0 ads, unlimited sessions, 0 accounts — the free tier is unlimited, and Premium is a one-time purchase, not a subscription (unlimited custom plans, history, JSON export). Built with Flutter, offline-first, in English and Russian.
