Hyper Zones turns time zones into something you can see instead of something you calculate. Track every city, colleague, and family member you care about, then move one slider to find the moment that works for everyone. WATCH THE DAY MOVE The curved sunlight slider shows daylight, not just digits. Sunrise, midday, and sunset curve across each location, so you can tell who is starting work, who is at dinner, and who is fast asleep before you send that message. FIND A TIME THAT WORKS Drag the slider and every location updates together. Pick any date, not just today, and check a meeting time across ten cities in a single gesture. Combo time zones flip between standard and daylight saving on their own, so a recurring call never quietly drifts by an hour. PLACES AND PEOPLE Add cities, or add the people who live in them. Import a contact, give them a photo, and you are following a person rather than a coordinate. Group anyone into tags, then watch a whole team on one slider. WIDGETS ON YOUR HOME SCREEN Keep your most important places on the Home Screen in small, medium, or large widgets. Each one carries the same sunlight preview as the app, so a glance is usually all you need. REMINDERS THAT ARRIVE ON TIME Set a reminder for any place or person and receive a Time Sensitive alert that can break through Focus. No more doing the mental math at 11pm and getting it wrong. SHARE WHAT YOU SEE Send a place as a rich card or as plain text, sunrise and sunset details included. Share an entire list at once when you are lining up a group. MADE YOURS Custom colors, icons, and photos for every entry. Adjustable visual density for compact or roomy layouts. Accessibility settings that genuinely adjust. EVERYWHERE YOU WORK iPhone, iPad, Mac, and the web, with your account keeping every device in sync. On Mac it also lives in the menu bar, one click away without leaving what you are doing. A SEARCH THAT KEEPS UP Cities, towns, and the smaller places most apps miss, with results that appear as fast as you can type. PRIVACY No tracking beyond what the app needs to run. Built by remote workers who got tired of miscounting the hours before a call. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
