ZoneAmigos
ZoneAmigos puts the people you work and chat with on a globe, shows their local time at a glance, and finds the best moment to reach them — meeting time in Work mode, catch-up time in Personal.

No accounts, no servers, nothing to set up. Add a few amigos and the map fills in.
Every amigo is a dot wearing a sombrero, coloured by what they're doing right now. Spin the globe or pinch the flat map.
starting soon · on shift · finishing up · offline — based on each person's own hours.
Drag through the day and watch everyone's colour change, and the daylight move across the map, to find an hour that works for all of you.
Pick an amigo and ZoneAmigos suggests when your hours overlap — a meeting window at work, a catch-up window for friends and family.
Get a nudge when someone comes on shift or when your window opens. Once, for a few days, or every day.
Two lists, two sets of hours. Colleagues and their shifts in one, friends and family and their sleep in the other.
Pick the version for your devices. Both are free to start, with a one-time $2.99 unlock for Pro.
The native app from the App Store. One purchase covers every iPhone and Mac signed in to your Apple ID.
The same app, in your browser at zoneamigos.app/app. Add it to your home screen or taskbar and it opens like any other app.
Installing it makes ZoneAmigos open full-screen from an icon, like a native app. It's the same web app underneath.
Free to try with two amigos. Pro is a single $2.99 purchase — no subscription, ever.
iPhone and Mac Pro is bought once through the App Store and covers all your Apple devices. The web version has its own $2.99 unlock with a licence key you can use in up to 5 browsers. The two are separate purchases. On the web there's no cloud sync — your amigos live in the browser you added them in, and Export & Import is how you back them up or move them.
ZoneAmigos runs no servers and collects nothing. Your amigos are stored on your device — and, if you turn it on, in your own iCloud. Location is used once, on your device, to find your nearest city. Read the privacy policy.
