Worldline
Different places. The same moment.

Captured from the development build
What it does
Keep the same moment understandable across cities, including time differences and daily context.
How it works
- Step 1Choose cities
The user keeps the places that matter in a small list.
- Step 2Compare local time
The same instant is interpreted in each city’s time zone.
- Step 3Find an overlap
Additional context helps distinguish a convenient hour from an awkward one.
- Step 4Keep it close
The platform-specific surface stays available without a large workspace.
