Time Zone Difference Planner

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 arithmetic before every call. TimezoneWorld lays your team across a single 24-hour band, colours the hours when everyone's actually at their desk, and ranks the best meeting slots by length — so "does 3 PM London time work for Sydney and Singapore?" gets answered the moment you open it. Most world clocks show you a row of times and make you do the hard part. TimezoneWorld starts where they finish: set each city's working hours, and its overlap engine does the real search — handling daylight saving shifts, half-hour zones like India, and quarter-hour zones like Kathmandu — to find the precise hours when every location is inside its working day. WHAT YOU GET • A 24-hour overlap band in your own local time — gold hours mean everyone is at their desk; tap one to see the exact local time and date in every city • Best meeting windows ranked by length, so the longest shared stretch is always top suggestion • Live clocks for up to 8 cities with an at-work 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're online • Single-tap sharing that writes the proposed meeting in every invitee's own local time and date PERFECT FOR • Remote teams spread across Europe, Asia, and beyond who lose precious time to scheduling • Freelancers and agencies booking calls across Europe, the US, and Asia in the same week • Long-distance families and couples wanting to ring while everyone's actually awake • Business travellers who need home time, destination time, and the difference 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 London 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. PRIVACY BY DEFAULT Everything runs on your iPhone from the system's own time zone database. No account, no sign-in, no tracking — and the app works completely offline. PREMIUM (PURCHASE REQUIRED) TimezoneWorld is unlocked by a single 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 everyone?" answer itself.
