Most workout timers assume you will watch a screen mid-set. Mid-set is exactly when nobody can: hands wrapped, floor work, music up, phone lying screen-down by the mat. Intertakt moves the whole interface to audio — voice cues and beeps over your own music, each channel at its own volume — so HIIT, Tabata and round sessions run with the screen off, survive incoming calls without resetting, and never ask for an account. The free tier is unlimited; premium is a single one-time purchase.
A hash run never stops so someone can check a map. The trail arrives as a call — On-On! — passed runner to runner over the noise of the pack, and heads stay up through whatever the terrain brings. Intertakt times interval training on that arrangement. A clear voice calls every interval over your own playlist, countdown beeps land in the final seconds, and music, voice and beeps each carry their own volume — the music never stops for the timer. Once you tap start, the screen never needs to light up again: pocket the phone and train. A call mid-round doesn't restart the session: it survives calls and app switches and resumes from the exact second it stopped. The free tier is unlimited — 0 ads, unlimited sessions, 0 accounts — and Premium is a one-time purchase, not a subscription: unlimited custom plans, history and JSON export. Routines are plain JSON, easy to move between phones. Built with Flutter, offline-first. Live on Google Play.
