Shipped: Intertakt 1.0 is live on Google Play

Launch day. Intertakt, an interval training timer I built solo with Flutter, is now live on Google Play: https://play.google.com/store/apps/details?id=com.intertakt.intertakt

The idea came from training itself: mid-set, a screen is the last thing anyone needs. So the app is built to be heard instead of watched. 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. 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.

Honest numbers: revenue so far is exactly zero - the app shipped this week. The free tier is unlimited (no ads, no accounts, no workout caps); Premium is a one-time purchase, not a subscription. Offline-first: no cloud, nothing to leak. iOS is next - the waitlist is open at https://www.intertakt.com/?src=openmakers

Fellow makers: I would genuinely value feedback on the audio side - mixing cues over background music turned out to be the deepest rabbit hole of the whole build.
