Features
Built around the work people actually need to finish.
Up to 12 zones at once
Pin 12 cities to a horizontal row — each shows local time, weekday, DST status. Drag the time slider; every zone updates instantly. Way more than the 3-city limit in the iOS World Clock.
Working-hour shading
Set each person’s working hours (e.g., Tokyo 9 AM–6 PM, Berlin 9 AM–6 PM, SF 9 AM–6 PM). The slider track shades green where everyone is at work, yellow where 1-2 people are stretching, red where someone is asleep. Find the only viable window instantly.
DST-aware export
Copy a meeting invite that reads “Tuesday 2 PM PT / 5 PM ET / 10 PM London / 11 PM Berlin / 7 AM Tokyo Wednesday” — including the right day-of-week per zone (your meeting can be Tuesday for you and Wednesday for Tokyo).
Travel mode
Going to Berlin next week? Pin Berlin to the top of the list; when you land, the app respects the iPhone’s new local time but keeps your origin zones for one-tap reference back to home colleagues.
Calendar event creation
One tap creates a Calendar event with the start time in your local zone but a note in the event body listing every other zone’s time. Recipients in other zones see the right time via Calendar’s native handling.
Lock Screen widget
Pick 4 zones to show on your Lock Screen widget. Quick check before texting a colleague “you up?”.

Read privacy policy FAQ
How is this different from the iOS World Clock? +
iOS World Clock shows times for cities you pin but doesn’t help find a meeting window across them. You eyeball it. Time Zone Planner has a draggable time slider with working-hour shading — you SEE the only 2-hour window where everyone is awake, instead of mentally calculating it.
How is this different from World Time Buddy or Calendly? +
World Time Buddy is a web app — great on desktop, awkward on phone. Calendly is for one-on-one scheduling with calendar conflict detection (and starts at $10/user/month). Time Zone Planner is for the planning step BEFORE the invite — deciding what time works for 5 people — on a phone, $19.99 once, no per-seat cost.
Does it handle daylight saving correctly? +
Yes — using the iOS time zone database (IANA tzdata). Meetings scheduled across DST transitions show the correct local time in each zone. The April-DST-confusion meeting (“wait, did we lose an hour?”) doesn’t happen.
Can I share the plan with someone who doesn’t have the app? +
Yes. Tap Share → it generates a plain-text summary (“Thursday 2 PM PT / 5 PM ET / 10 PM London / 11 PM Berlin / Friday 7 AM Tokyo”) you can paste into Slack, email, or a calendar invite description. No account needed on either side.
Will my meeting data leave the device? +
No. The app pins city names to your device (using the iOS time zone database) and runs the time math locally. There is no Swarmval backend; meeting plans never sync to a server. Calendar event creation uses Apple’s EventKit — the event lives in your Apple Calendar, not ours.
Does it work on iPad? +
Yes — with a wider layout that shows 12 zones in a single row instead of scrolling. Stage Manager compatible. Apple Pencil for pinning zones via search.
