Dzvin turns your screen into a living clock. Every second, the digits don't just change, they morph. Liquid, shatter, split-flap, nova and more: ten ways to watch time move, in six typefaces. Behind them an aurora drifts with the hour, from sunrise amber to midnight violet. Or true black, if you'd rather. And it's a full clock, not just a pretty face: • Alarms on your Lock Screen, powered by AlarmKit. They ring on time even when the app is closed. • Every-2-weeks alarms, built for rotating shifts: each week rings on its own schedule. • Timer: a neon countdown in the Dynamic Island and on the Lock Screen. • Pomodoro focus timer. • Stopwatch with laps. • World clock for the cities you care about. • Nightstand mode: a dimmed, always-on bedside clock. • Home Screen widget. Dzvin Pro is one payment, yours forever: every morph style and typeface, Pomodoro and nightstand mode, plus every Pro feature we add later. No subscription. Private by design: • No account, no sign-up • No ads, no tracking, no data collected • Works fully offline Just time, in motion.

Verdict
The clearest difference is price: Dzvin at Free against WAI's $0.99. WAI's advantage is in-app purchases (none vs 1) and iOS requirement (18.6 vs 26.0). On update cadence, ads and device support there is nothing between them.
