Open a route someone sent you
Add a route that arrived by AirDrop, message, email or file — including a GPX from a plotter or another app.
Tap the file wherever it arrived — AirDrop, Messages, Mail, Files — and theONE opens a preview instead of adding it straight away. Two kinds of file work: a .theoneroute from another boat running theONE, and a .gpx from a chartplotter or another app.
The preview shows the line on a chart, how many waypoints it has, how far it runs, and where it came from. Rename it before you add it if you want.
It also runs a depth check against YOUR boat — your draft and your minimum operating depth, not the sender's. The captain who sent it had no way to know what you draw. If you have not set a draft yet the preview says so rather than checking against nothing; unchecked water is never reported as safe.
If you already have the same line, the preview says which route it matches. It still lets you add it — nothing of yours is replaced or removed.
A GPX that is a recorded track can hold thousands of fixes. Those are thinned to 500 evenly spaced points so the route stays workable; the start and the end stay exactly where they were, and the preview tells you it happened.
Nothing is added until you tap Add to my routes.
Steps
-
Tap the file
Open the attachment in Mail or Messages, accept the AirDrop, or tap the file in Files. theONE opens the preview.
-
Read where it came from
A route from another theONE shows the sender's name, their boat and the date. A plotter file reads "From a GPX file" — GPX carries no author, and no passage notes either.
-
Check it against your own boat
The preview runs the same chart depth check the route library uses, against your vessel's operating floor. Read it before you add. Nothing re-routes the line for you.
-
Rename it if you like
The name field is editable. Leave it alone to keep the name the sender gave it.
-
Add to my routes
The route lands in your route library as a new entry — yours to edit, reverse, follow or delete. The row remembers who sent it.
