Zoneline shows when people in different time zones are awake, ranks the best hours to talk, and makes a shareable card for the time you pick.
Tap the plus button, search for a city, and optionally type the person's name. Drag the rail at the top of the board to move the time. Gold on the rail marks hours when everyone is awake.
A time looks wrong. Zoneline uses your device's time zone data. Update iOS if a government changed its clock rules recently, and check the place you added is the right zone (open it from the board).
Someone sleeps at different hours. Tap their row, then change Wakes up, Goes to sleep and the work hours. Weekends follow each country's own calendar.
