Unichrono Pro is free until the end of 2026. Claim the lifetime unlock on the paywall. Nine widgets in your own colours, 34,804 cities, nothing leaving your iPhone. 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.

Your widgets take your colours now. Every widget accepts a text colour, an accent and a background — from a set of presets, or from a custom palette you mix yourself. Text that would be unreadable on the background you picked is corrected rather than drawn that way. Four more widget designs. Hero City gives one place the whole widget, and Three Cities arrives as Day Wash, which paints each city with the colour of its hour, and as Rings, which shows the same three as dials. The row-list widgets can also lay out as a grid. Widgets have parts you can switch off. The day and weekend chips, the availability dot, the day wash and the dotted map are each a switch, per widget. The second line is yours to choose too — country, UTC offset, the difference from where you are, or the sun's times — wherever the design has room for it. Widget text is set in Figtree, the app's own typeface, with a small accented AM/PM marker. The alarms you set through Unichrono are now listed, editable and cancellable. iOS does not name an alarm for you, so the app keeps the names itself. Alerts moved in beside Alarm and Meeting, because an alarm, a meeting and a city alert are the same kind of thing. An alert is seeded from the city's own clock, set to Once or Weekly, and shows a countdown on its row. 34,804 cities, up from 6,312 — the same dataset the Android app carries. Every country reaches at least 25 cities where there are that many to have, so smaller countries are no longer just their capital. Kosovo is here for the first time. Search folds accents and the seven letters that do not decompose the usual way, a Turkish dotless i among them. Settings can now reach the help guide, the website and a feedback form, with your app version, device and iOS version already filled in. Unichrono also asks you to rate it once, on the way out, and takes "already rated" for an answer. Unichrono Pro is free until the end of 2026. Claim it on the paywall; it is the same lifetime unlock, and it stays yours after the offer closes. Fixes: Speak alerts were silent. The widget ground followed the device appearance instead of the theme you chose. The widget gallery said a widget was placed where it was not, and a one-city library now previews with sample cities rather than an empty card.
