An interval training timer for Android, built with Flutter and offline-first. It plays over your music — beeps and voice cues ride on top, each with its own volume — and the session runs with the screen off in your pocket. An incoming call pauses the round instead of killing it, and the workout resumes from the exact second. HIIT, Tabata, custom rounds in whole seconds.

Solo build by one indie developer. No ads, no account, no workout caps; the free tier is unlimited, and Premium is a one-time purchase (custom plans, session history, JSON export). Just launched on Google Play; the iOS waitlist is open at intertakt.com.
