Alt Time puts the times you actually need on your lock screen and home screen. See the opposite of your iPhone's clock format at a glance. If your phone shows 12-hour, the widget shows 24-hour — and the other way round. It follows your system setting automatically, so there is nothing to keep in sync. WHAT YOU GET Dial — a home screen clock face with two rings of numbers: 1–12 outside, 13–24 inside. The hour hand points at both at once, and the centre shows the time both ways, like 5:57 PM and 17:57. Small, medium or large, in ten finishes including parchment and black enamel. Show your own time or any city from your world clock. Travel Mode — your home time and the time where you are, side by side on your lock screen and in the Dynamic Island while you travel, with how far ahead or behind home you are. In 12-hour, 24-hour, or both. Start and stop it from Shortcuts or Siri. Requires iOS 18. AM / PM — the lock screen clock never shows AM or PM. Three widgets do: just AM or PM, the time of day (Morning, Afternoon, Evening or Night), or both together, with no numbers to read. Put one beside the date or below the clock. World clock — a home screen widget in small, medium or large, showing as many cities as you like in eight color finishes, with a sun and moon day-night glance. Looks right in StandBy. Alternate 12h/24h time — always the opposite of your system setting, updated automatically. Second time zone — search about 69,000 cities, not just capitals, and see that city's time labeled with its name. UTC / military time — 24-hour Zulu time for pilots, sailors, and anyone working across zones. Dual-time widget — two times side by side in a single lock screen slot, sized to match. Lock screen and home screen widgets, in circular and rectangular slots, tinted or clean, on iPhone and iPad. Every setting sits in one short menu that leads with your times, live. COMPLETELY OFFLINE The city database is built into the app. Searching it needs no network, so Alt Time works in Airplane Mode, on a plane, or with no signal at all. Nothing is uploaded, because there is nowhere for it to go. NO SUBSCRIPTION One purchase. No subscription, no ads, no account, and no data collected, stored or transmitted — ever. Requires iOS 17 or iPadOS 17 or later. Travel Mode requires iOS 18 or later. See every widget and how it works at mmhadventures.com/alttime
World Clock Widget

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. With Time Capture, paste a date, time, and city, review the details, and convert the confirmed moment across your saved clocks. Reviewing a captured time is free; applying it uses Plus or the Convert preview. UPCOMING TIME CHANGES See each saved city’s next clock change within 30 days and how its time difference from another saved city will change. Included free. 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. WORLD ALARMS With Meridian Plus on iOS and iPadOS 26 or later, set a one-time alarm for a saved city’s local date and time. See the matching time on your device before you enable it, or turn a future moment in Convert into an alarm. Open World Alarms from the alarm-clock button on the main screen. Alarms stay tied to the moment you confirmed, even when you travel. YOUR CLOCKS EVERYWHERE • iPhone and iPad layouts built for each screen. • Focus, Constellation, Solar Atlas, and interactive Time Lens widgets. • An extra-large iPad Solar Atlas for up to eight saved cities. • Pin a city or follow your selected clock. Tap a widget to open its city. • Choose a Time Lens comparison session in Edit Widget to step through time. Other clock widgets stay live. • 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. Home Screen widgets, including the extra-large iPad Solar Atlas, 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 and World Alarms. World Alarms requires iOS or iPadOS 26 or later. 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 clearest difference is price: World Clock Widget at Free against Alt Time's $1.99. World Clock Widget also leads on update cadence (weekly vs every 3 weeks). Alt Time's advantage is in-app purchases (none vs 1) and chart position (#55 vs unranked). On ads, device support and iOS requirement there is nothing between them.
