PREMIUM — PURCHASE REQUIRED: All features described below are part of Pro and require a purchase: a weekly or yearly auto-renewing subscription, or a one-time lifetime purchase. Know what time it is in any city right now — and exactly how far it sits from your own. WorldClock keeps every place you care about on one live board: the local time, the offset from home down to the minute, whether it is today or already tomorrow there, and a day–night band that shows at a glance who is awake. Every clock is computed from the IANA time zone database in iOS for the exact moment on screen. Nothing is stored as a fixed offset, so daylight saving changes take effect on their own — the board is right the morning the clocks jump, not a week later. Half-hour and quarter-hour zones are first-class: Kolkata reads +5:30, Kathmandu +5:45, Chatham Islands +12:45 — never a rounded-off "+5h". WHAT YOU GET • Your whole world on one screen — Tokyo already tomorrow morning, San Francisco still yesterday evening — each city with a live day–night band showing who is awake right now. • Offsets that read from YOUR home city, minutes included. Land somewhere new, swipe once to move home, and every clock re-anchors instantly. • A meeting planner: pick a moment in your home city and read it in every city at once, colour-coded green, amber or red against working hours — before you hit send on the invite. • Share a meeting plan in one tap — "London: 16:00 · Tokyo: 01:00 (tomorrow)" pasted straight into the chat, dates included. • A searchable catalog of cities covering every UTC offset on Earth, each row carrying its country, zone abbreviation and UTC offset — so BST vs GMT is never a guess. • Today / Tomorrow / Yesterday labels on every clock, so a late call with Sydney never lands on the wrong date again. PERFECT FOR • Remote workers whose team spans three continents and one very awkward Wednesday. • Travelers who want home re-anchored the moment they land, not after mental arithmetic. • Long-distance families who just want to know whether it is too late to call. • Anyone who has ever scheduled a call for the right hour on the wrong day. WHY NOT JUST USE THE BUILT-IN CLOCK? It shows times, not answers. It will not tell you the offset from home down to the minute, whether it is already tomorrow there, or what Friday 9:00 becomes in Auckland — and it has no way to test one meeting time against everyone's working hours before you commit to it. PRIVATE BY DEFAULT No account, no location access, no tracking. Your city list lives on your device, and every time is computed there — offline — from the time zone database built into iOS. PREMIUM (PURCHASE REQUIRED) WorldClock is a paid app. One purchase unlocks everything: an unlimited city board, the meeting planner across every city you track, and your own working-hours window. Choose Weekly, Yearly, or Lifetime — whichever fits how long your world stays spread out. Add your first city and watch the board come alive.
