Escape rooms solved the busy-hands problem years before fitness apps noticed it. The clock lives in the control room. A gamemaster reads it aloud. Hints arrive as a voice over the noise of the room, and nobody steps away from a puzzle to check a watch.
Intertakt runs interval training on the same arrangement:
- Voice over your playlist. A clear voice calls every interval and the halfway mark; countdown beeps ride on top, each channel with its own volume.
- The screen never has to come back on. Start the session, put the phone face-down, on Do Not Disturb — the timer keeps time in your pocket from warm-up to the last round.
- A held clock, not a reset. An incoming call or app switch pauses nothing that matters: the round resumes from the exact second it stopped.
- Short accounting. 0 ads, ∞ sessions, 0 accounts — the free tier is unlimited. Premium is a one-time purchase, not a subscription: custom plans, history, JSON export.
