Portside
Includes Mariner Pro upgrade — global routing, $14.99 once
A quiet, offline-first logbook for the vessels you've sailed on, the ports you've visited, and the rank you held at the time.
Portside is a personal log of the vessels you've sailed on, the ports you've visited, and the rank you held at the time. It works fully offline — because at sea you can't count on a signal.
Built as a personal log first — the features exist because I needed them at sea.
Every vessel grouped by sign-on session. Name, call sign, IMO, and rank held at the time — kept clean and separated.
Ports sorted by latest departure, with a clear SIGNED OFF marker on the port where each voyage ended.
Download coastal regions you'll actually need. Charts render with no signal — coastline, ports, and seamarks only.
Sign in and your log travels with you across devices. Don't want it? Use Portside fully offline forever — no account needed.
Your data is yours. Export the whole log as JSON or CSV anytime. Import it back into a fresh install without losing a thing.
Follows your system appearance — cream by day, deep nautical blue by night. Everything re-themes quietly.
The most advanced A* routing algorithm you can hold in your pocket — completely offline. Plan a route between any two ports on Earth, close any canal or strait, and export to any ECDIS.
