Sun TimeZone

Timezone turns world clocks into something beautiful.
Instead of a list of numbers, watch the sun’s path across a 24-hour cycle as a smooth sine wave, with your selected cities plotted directly on the curve. A dynamic sky gradient shifts from starlit night to golden sunrise to bright day, making it instantly clear who’s awake, who’s asleep, and where the sun is.

INTERACTIVE TIME DIAL
Drag the scrubbing dial to glide through any hour of the day. Subtle haptic ticks mark each hour, while every timezone updates in real time. Perfect for finding that sweet spot where Tokyo, London, and San Francisco overlap.

SUN PATH VISUALIZATION
A scientifically inspired sine wave maps the sun’s arc over 24 hours. Each city appears as a color-coded marker, so you can immediately see which locations are in daylight and which are in darkness.

DYNAMIC SKY & STARS
The background is a living sky that transitions from deep midnight blues to warm sunrise tones to bright daytime hues. Softly twinkling stars animate across night regions, adding depth and atmosphere.

SMART CITY SEARCH
Add timezones by simply searching city names like “New Delhi,” “San Francisco,” or “Tokyo”—no need for IANA identifiers. With 50+ built-in aliases, you can also browse by region or GMT offset.

DESIGNED FOR APPLE
Crafted with Liquid Glass materials, fluid animations, and a dark-mode-first aesthetic. The layout adapts seamlessly: a compact stacked view on iPhone and a spacious side-by-side layout on iPad.
