Intertakt
Intervals called out loud. Screen stays off. Music stays on.
In their words
Navigation apps worked this out years ago: nobody drives while staring at the map, because the voice says where to turn. Intertakt runs interval training the same way. A clear voice announces every interval and the halfway mark; countdown beeps sit over your own playlist — music, voice and cues each keep their own volume. The phone spends the session face-down with the screen off, on Do Not Disturb, in a pocket, on the bench. Nothing in the workout asks to be looked at.
Interruptions are cheap: take a call, switch apps, and the round resumes from the exact second it stopped.
0 ads · ∞ sessions · 0 accounts — the free tier is unlimited: the whole timer, every session. Premium adds unlimited custom plans, history and JSON export, priced as a one-time purchase: there is no plan to cancel later, because there is no plan.
Built with Flutter, offline-first. Coming soon to Google Play; the waitlist and founding pricing are open at intertakt.com.

What is Intertakt?
Interval training runs hands-free without staring at a display. Intertakt plays countdown beeps and voice cues directly over an existing music playlist while the phone stays face-down in a pocket or on the floor. Background audio engineering keeps the schedule running while the screen is locked, and independent volume controls let users balance the voice, beeps, and music.
Three steps. Then you forget it's there.
Preset protocols like Tabata 20/10, HIIT, and custom desk breaks load in a single tap, or trainers can build custom intervals where each round holds its own specific duration. Once a session starts, stray pocket touches cannot pause the work because lock mode secures the display. When an incoming phone call interrupts the session, the app preserves the exact second and round, displaying a clear resume button instead of resetting the workout to zero.
Workouts that don't vanish.
Every change autosaves immediately on the device without requiring an account or cloud profile. The free tier includes unlimited sessions, all preset routines, voice cues in English, Russian, and Spanish, and up to three custom plans. Premium removes custom plan caps, adds session history, and allows users to export and import routines as plain JSON files. The app operates fully offline-first, and the early bird purchase is priced as a one-time payment rather than a recurring subscription.
