Intertakt

Intertakt is built the way a good turn signal is built: the relay click carries the information, so nobody has to watch the lamp. Voice and beep cues ride on top of your own music, each with its own volume, and the session keeps running with the screen off in your pocket. No ads, no account, no workout caps; an incoming call pauses the round instead of killing it. HIIT, Tabata, custom rounds in whole seconds. Live on Google Play today; iOS waitlist open — one email when it ships.

Best for: Anyone who trains to their own music: HIIT, Tabata, home and gym rounds
