The dialTropical · real data

Angles are exact. Distances are squashed so Saturn fits on a phone.

Today's sky, decoded

People

Save a chart, then ask the box about them by name. Birth data stays on this phone; the only exceptions are ones you trigger: asking the brain about someone by name sends their chart with the question, and sharing (the ↗ link, or a Share image of an open chart) carries that person's name and birth details in what you send, and a backup file holds all of them in plain text.

These charts live on this phone only. Clearing your browser data, or losing the phone, takes them with it. A backup file is the only way to get them back, so save it somewhere that isn't this device. Restoring adds to what you already have, it never overwrites it. The file also carries your saved date-checks.

Check a date

"Is the 14th alright for this?" Pick a person, a thing, a day, and where you'll be. You get the litha's lean with its working shown, the times to dodge in that place's own clock, and the sky against their chart. A suggestion, never a sentence.

One date checks that day. Add the second date to sweep a stretch: up to 90 days, one line per day, tap a day for the full read. Where will you be? Travel counts: the windows follow the place, not your phone. Nearest big city is fine; sunrise shifts by minutes across a region, not hours.
