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. Stop doing time zone math before every call. TimezoneWorld lays your whole team on one 24-hour band, colors the hours when everyone is actually at their desk, and ranks the best meeting windows for you — so "does 9 AM my time work for Sydney?" is answered the moment you open the app. Most world clocks show you a row of times and leave the hard part to you. TimezoneWorld starts where they stop: you set each city's working hours, and its overlap engine walks the real calendar — daylight saving shifts, half-hour zones like India, even quarter-hour zones like Kathmandu — to find the hours when every city is inside its working day. Tap any hour on the band and see exactly what the clock reads in every city, and on which date. WHAT YOU GET • A 24-hour overlap band in your own local time — gold hours mean everyone is at their desk; tap one for the exact local time and day in every city • Best meeting windows ranked by length, so the longest shared stretch is always suggestion number one • Live clocks for up to 8 cities with an at-their-desk indicator, chosen from 400+ searchable time zones • Working hours per zone — set Berlin to 8–16 and Sydney to 10–18 and the overlap recalculates instantly • A daily reminder the moment your team's shared window opens, so you catch everyone while they are online • One-tap sharing that writes the proposed meeting out in every invitee's own local time and date PERFECT FOR • Remote teams spread across continents who lose the first ten minutes of every week to scheduling • Freelancers and agencies booking calls with the US, Europe, and Asia in the same week • Long-distance families and couples who want to ring while everyone is actually awake • Travelers who need home time, destination time, and the difference between them at a glance WHY NOT JUST USE A WORLD CLOCK? A world clock tells you it is 3 AM in Tokyo. It does not tell you when Tokyo, Berlin, and Chicago are all working at the same time — that is a search across 24 hours and every zone's own working day, with daylight saving moving the goalposts twice a year. TimezoneWorld runs that search for you and simply shows the answer. PRIVATE BY DEFAULT Everything is computed on your iPhone from the system's own time zone database. No account, no sign-in, no tracking — and the app works fully offline. PREMIUM (PURCHASE REQUIRED) TimezoneWorld is unlocked by a single purchase of your choice: a Weekly subscription, a Yearly subscription, or a one-time Lifetime purchase. Full access includes all 8 zone slots, the 24-hour overlap band, ranked meeting windows, per-zone working hours, the daily overlap reminder, and meeting-time sharing. Add your cities, set the working hours, and let your next "when works for you?" answer itself.
