Tempus World Clock vs Unichrono

Tempus is a world clock and time zone converter built for people who work, travel, and stay in touch across time zones. It is at home on iPhone, iPad, and Apple Watch. NAME YOUR CLOCKS Add clocks for cities or for the people you talk to. Give each one a custom name, an emoji, and a color tag so "Mum in Sydney" or "Design team, Berlin" is readable at a glance. Choose emoji from a searchable catalog with recents and suggestions for the city. Pick analog or digital faces, 12 or 24 hour time, and see the time difference from wherever you are. CONVERT TIMES INSTANTLY Pick any time in any zone and see it in all your clocks at once. Drag the time scrubber to slide through the day and watch every clock move together. Day and night indicators follow the working hours you set for each city, so you can see at a glance who is reachable. PROFILES Group your clocks into profiles such as Work or Family and switch between them from the title on iPhone or the sidebar on iPad. A city can be in several profiles, and the active profile syncs to your other devices and Apple Watch. REMINDERS IN ANOTHER CITY'S TIME Set a reminder for 9:00 in Tokyo and Tempus alerts you when it is 9:00 there, whatever time it is where you are. Anchor a reminder to the city or to your own time, repeat it every day or on the weekdays you choose, or set it for a single date. Label it, pause it without deleting it, and turn alerts off on a device you would rather keep quiet. ON THE LOCK SCREEN Keep a reference city in the Dynamic Island and on the Lock Screen, with its current time and how far ahead or behind you it is. A countdown appears there before a reminder is due. FIND A MEETING TIME THAT WORKS Select two or more clocks, set working hours for each, and Tempus shows the overlapping windows where everyone is available. Add the meeting to your calendar in one tap or share it as an .ics invite. CITY DETAIL Tap any clock for a full city view: a skyline illustration that changes with the time of day, sunrise and sunset on a daylight arc, and current weather conditions. IPAD On iPad, Tempus uses a native split layout: browse your clocks in a sidebar while City Detail stays open beside them. Time Converter and Meeting Finder open in the detail column with room for a full-width overlap timeline. Keyboard shortcuts and pointer hover are supported throughout. APPLE WATCH Tempus on Apple Watch shows your clocks on your wrist, lets you convert times with the Digital Crown, and offers complications for your favorite clocks. Clocks sync instantly between iPhone and Apple Watch. WIDGETS AND SYNC Home Screen widgets keep your clocks in view. Your clocks sync across all your devices with iCloud. PRIVACY FIRST Tempus has no account, no ads, and no tracking. Your clocks are stored on your device and in your private iCloud database. Weather is provided by Apple Weather for the cities you add, never for your own location.

It's 9 in the morning where you are. Is it too early to call your mother? Is your team in Berlin still at their desks? Will anyone in Tokyo read this tonight? And what time will it be in Lisbon when you land? Unichrono answers all three from your Home Screen, without you opening anything. PUT THEIR TIME WHERE YOU ALREADY LOOK Add the cities your people are in, then place a widget. One city, big enough to read across a room. Four cities in a row. Eight in a grid. A clock face. Your Lock Screen too, in every shape Apple allows. Every widget is yours to set up: which cities it holds, 12 or 24 hour, which theme, and what the second line says. KNOW BEFORE YOU SEND IT Each city carries the shape of its own day, so you can see it instead of working it out. A wash of colour for morning, afternoon, evening and night. Yesterday or Tomorrow when the date has already turned over there. Sunrise and sunset. And a dot for each city — green while they are inside their own working hours, amber at the edges, red when you would be waking them up. WORK OUT THE TIME BEFORE YOU GO Add the city you are flying to and it sits beside home, with the offset spelled out, so the gap is a fact rather than arithmetic you do at the gate. Drag the ruler to your landing hour and see what everyone back home will be doing when you touch down, and whether that is a reasonable time to text. Sunrise and sunset tell you what daylight you are arriving into. Once you are there, your own row moves with you and the people you left behind stay where they are. PLAN WITHOUT THE ARITHMETIC Drag the ruler along the bottom of the screen and every clock moves together, so you can find the hour that works for all of you before you propose it. Jump to a date months out and see what it looks like there. Once you have found it, set an alarm for their morning, drop the meeting into your calendar, or copy an invite that reads correctly in every zone. Unichrono can also say a city's time out loud, at an hour you pick. 6,312 cities are built in, from capitals down to small towns. Search happens on your phone; nothing is fetched. IT NEVER ASKS YOU FOR ANYTHING No account. No sign-in. No ads. No analytics. No tracking. Switch on Airplane mode and every clock in this app keeps telling the truth, because not one of them was ever asking a server. Unichrono has no backend to send your data to, because it does not need one — the time zone rules ship inside the app. WHAT IT COSTS Free, and staying free: 3 cities, the World Clock widget in every size, Hero City, Lock Screen widgets, time travel, the plan board, themes, and the full city search. Unichrono Pro is one payment of USD 2.99. It is not a subscription and never becomes one. Pro adds unlimited cities; every other widget — Two Cities, Three Cities in a day-wash or rings style, Analog, Sun Clock and Availability; the denser grid layout; extra widget detail lines, such as how long until they close; spoken city alerts; the hourly or daily time announcer; and the plan board's alarm, calendar and invite actions. Launch gift: until 31 December, all of that is free. Open the app, tap Claim, and it stays unlocked on your iPhone. No account, no subscription, nothing to renew.
