Sun TimeZone

Read full description

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. KEY FEATURES - Sun-path sine wave with color-coded timezone markers - Interactive horizontal dial with haptic feedback - Animated day-to-night sky gradient - Twinkling star field in night zones - 8 vibrant accent colors for cities - Searchable picker with 50+ city aliases - Persistent state across launches - Responsive layouts for iPhone and iPad - No ads, no accounts, no tracking Whether you're coordinating across time zones, planning a call with family abroad, or simply curious where the sun is right now—Timezone makes it intuitive, visual, and immediate.

Your world should read like a clock, not a spreadsheet. Meridian is a clock-first world-time instrument for the places that matter to you. Instead of scanning unrelated clocks, see every saved city around one live 24-hour solar face. Daylight, local dates, and relative offsets stay visible together, so the shape of your world makes sense at a glance. ONE FACE, EVERY CITY • Focus any saved city with one tap. • Read its local time, date, UTC offset, solar state, sunrise, and sunset. • See every other city relative to the one in focus. • Follow half-hour and quarter-hour time zones accurately. CONVERT EXACT MOMENTS With Meridian Plus, choose a date and time to see the matching local time and day in every saved city. Meridian follows the time-zone and daylight-saving rules carried by the operating system, including skipped and repeated local times. The last three moments you converted come back as one-tap rows. SOLAR ALERTS With Meridian Plus, have sunrise, sunset, golden hour, blue hour, and solar noon announced for any saved city, on time or up to 30 minutes before. YOUR CLOCKS EVERYWHERE • iPhone and iPad layouts built for each screen. • Small, medium, and large Home Screen widgets. • Lock Screen and StandBy views. • Apple Watch app and complications. • Private iCloud sync between your devices. PRIVATE BY DESIGN There is no Meridian account, advertising, analytics, or tracking. Manual city selection provides the complete core experience. When you choose Current Location, Meridian sends coordinates to Apple map services to resolve the place and time zone. It stores the coordinates with the saved clock, which may sync through your private iCloud account. The developer cannot access those coordinates or iCloud data. Solar calculations run on your device. FREE AND FAIR Free includes two clocks. Small, medium, and large Home Screen widgets, Lock Screen widgets, Apple Watch, complications, StandBy, iPad, iCloud sync, renaming any clock, and UTC reference clocks stay free. Meridian Plus raises the limit to eight clocks, unlocks Convert, and adds solar alerts. Buy it once with your Apple Account. It never expires, and there are no recurring charges. Meridian uses your device's operating system clock and time-zone information. It does not claim independent atomic-clock accuracy.

Verdict

The call
