Passage planning
Create and adjust waypoints, review leg assumptions, inspect marine places and export GPX before leaving shore.
Sailing companion
Plan ashore.
Sail with context.
Build a waypoint passage, explore source-labelled marine context, carry the route aboard and optionally coordinate a private crew — without creating an account.
Solo-first · offline-first · iPhone and Android
Built for a passage
Useful alone. Connected when the crew needs it.
Underway context
Keep route, live GNSS state, wind, calculated tide information, local AIS targets and manual MOB recovery context together.
Private crew sharing
Share a temporary voyage by code, QR or private app link. A solo voyage remains useful without a relay or account.
Closed field testing
Help test before it goes to sea.
Tester releases are private and experimental. Install through the invitation channel for your platform, report the version and build shown under Settings → About & build, and never rely on a test build as your only source of navigation information.
Open TestFlight for iPhone
Android closed testing
Invitation-only. There is no public opt-in link; existing testers receive access directly through the private tester group.
