Intertakt

A bowling alley runs on frames, not on a clock. Between deliveries the pinsetter clears and racks the pins on its own - nobody steps onto the lane to reset anything by hand - and the game simply steps from frame to frame while the bowler keeps bowling. Intertakt times training the same way.

It is an interval timer for Android: HIIT, Tabata, EMOM and desk-bound circuits. Fix the plan once - take a template or build your own workout - and the app walks every work and rest block in order. A clear voice calls each change and the middle of each work block; countdown beeps sit on top of your own playlist, each channel at its own volume. From the first beep the session runs with the screen off - in a pocket, on a desk, face out of sight.

A phone call is a fouled delivery, not a new game: nothing resets, and the workout picks up mid-block, right where the interruption landed. Plans are racked in advance like frames, so a session is never improvised on a screen.

The house rules are three numbers - no ads, unlimited sessions, no accounts - and the free tier is the full game. Premium adds custom plans, history and JSON export as a one-time purchase, never a subscription. Offline-first, built with Flutter, EN+RU. Released on Google Play on October 17, 2026. The timer speaks over the playlist and never asks for the screen.
