Ask any music student how an interval is learned: not from a page, but by listening. Two notes; the gap between them is measured with the ear. Interval training works best on the same interface — that is the bet behind Intertakt.
You build the workout on screen: HIIT, Tabata, EMOM or rounds, typing a short label for each work and rest block. Press start, and from there the display stops mattering. Voice cues and countdown beeps play over your music with independent volumes, the plan works with the screen off, and a call, an app switch or a locked screen only pauses the story: the session resumes on the exact second it left. 0 ads, unlimited sessions, no accounts.
The free tier is a complete timer. A one-time purchase — never a subscription — adds unlimited custom plans, session history and JSON export. Flutter, offline-first, coming soon to Google Play — waitlist open at intertakt.com. An alternative to Interval Timer, Seconds and Tabata timers for anyone training with headphones on.
