Live Activities & Dynamic Island: your active workout session now lives on the Lock Screen and in the Dynamic Island (requires iOS 17+; Dynamic Island on compatible iPhone models). Track your current phase, interval number, target heart-rate zone, and a live countdown that stays accurate whether the app is open or closed. Pausing in the app holds the countdown; finishing or stopping clears it automatically.
Accessibility improvements: main action buttons on the Today screen now wrap cleanly at large Dynamic Type accessibility sizes instead of shrinking.
Level-up acknowledgement: advancing to a new earned level after an update is now clearly highlighted on launch rather than applied quietly.
Localization polish and translation refinements across all supported languages.
v1.2August 2026
Full localization across English, Polish, German, and Spanish. Every screen, HealthKit permission prompt, and guided voice cue now matches your device language.
v1.1August 2026
A gentle, dismissible starting-level suggestion informed by your VO₂max from Apple Health. It compares against published fitness norms to suggest a sensible rung, but never picks for you — your choice always wins.
Go back during onboarding: step back through earlier questions without starting over.
Edit your age in Settings with your heart-rate zones updating automatically.
Erase your health data from your device in one tap from Settings.
The Level Ladder now opens as a sheet to avoid gesture conflicts with tab navigation.
Accessibility and contrast polish across the active workout screen.
v1.0August 2026
First release on the App Store.
Couch-to-4×4 progressive on-ramp: start with intervals as short as 30 seconds across eight progressive levels.
Voice-guided sessions that keep running while your screen is locked and your music is playing.
Personalized 85–95% heart-rate work zones derived from your age or set manually.
Apple Watch handoff and Apple Health integration — completely private, with no account, no ads, and no tracking.
Gentler Base Camp level: sub-1:00 entry rung (4×30s effort) for beginner familiarization.
