Turn a long-running customer state into a persistent product surface.

Fasting and eating windows lasted for hours, while standard push notifications could only create isolated moments of attention. Live Activities offered a way to keep the current state visible and actionable directly from the lock screen.

I owned the concept, product specification, UX and experiment design. Together with engineering, we handled an important platform constraint: Live Activities could last roughly 8–12 hours while an average fast lasted around 14, so local notifications remained as a fallback even at the cost of occasional duplication.
