What Astrolabe can do

Astrolabe shows the time in eight cities on a single dial. Here is everything it can do, with a way to try each feature right away.

  1. Read every city at a glance

    Each coloured ring is a city, turned to its own local time. Read straight down the red line at the top to see the current time everywhere at once. Light sections are daytime and dark sections are night. The World time card lists the same times in words, with how far ahead or behind each city is.

  2. Turn the dial with your hand AI · on-device

    Turn on the camera, then pinch your thumb and index finger to grab the dial, move your hand round in a circle to turn it through time, and let go to leave it there. Hand tracking runs entirely in your browser, so no video ever leaves your computer.

  3. Drop anything with a time in it AI

    Drag in a screenshot of a meeting invite, a flight confirmation or a chat, paste one with ⌘ V, or type a sentence such as “standup at 9:30 IST tomorrow”. AI reads the dates, times and time zones, and the dial turns to each one it finds.

  4. Find a meeting time across cities AI

    Ask for a meeting in plain words, for example “a one-hour call with New York and London next week”. Astrolabe finds the first slot when everyone, including you, is within working hours (9 AM to 5 PM on a weekday). The dial lights up those cities' working hours and marks the overlap with a red wedge.

  5. Move around

    When several times are found, step through them with ← and →. Press Esc or Back to now at any point to return to the live time.
