About

Dzvin

Features
Read full description

Dzvin turns your screen into a living clock. Every minute, the digits don't just change β€” they morph, flowing like liquid metal from one shape into the next. It's mesmerizing, calm, and unlike any clock you've used. Behind the time, a gentle aurora drifts and shifts with the hour, so your clock is never quite the same twice. And it's a full clock, not just a pretty face: Alarms that actually wake you β€” powered by AlarmKit, they ring on time even if the app was closed, right on your Lock Screen. Timer β€” a neon countdown that lives in the Dynamic Island and on the Lock Screen, so time-left is always a glance away. Stopwatch β€” precise laps that keep running in the background. Themes β€” a set of hand-tuned neon palettes for any screen, day or night. Made for you, and only you: β€’ No account, no sign-up β€’ No ads, no tracking, no data collected β€’ Works fully offline β€’ Free Simple, beautiful, private. Just time β€” in motion.
