Before you start.
Can I save a meeting to my calendar?
Yes, with Hourline Pro. Choose a city's time, check the other local times, then set the event's duration, repeat schedule and reminder. Hourline writes it to the calendar you choose.
Does the app account for daylight saving?
Yes. City clocks use the time-zone rules for the date you are viewing. When countries change their clocks on different dates, their time difference can change too.
Can I see my existing calendar events?
You can opt in to Events on the Ruler in Settings → Calendar. Those events are read on your device. Calendar access is optional.
Which devices run Hourline?
Hourline supports iPhone and iPad on iOS or iPadOS 18 and later, and Apple Watch on watchOS 11 and later. City Stroll has the additional requirements described above.
What about privacy?
Your cities and settings stay on your device, with your chosen cities also shared with your paired watch. Weather, purchases and City Stroll use the services described in the privacy policy. There are no ads or cross-app tracking.
