Compass 2050 is a private voyage log and on-board organizer for Android. It uses your phone's GPS, compass and barometer; voyage data stays mostly on device — no cloud account.
Supplementary tools only — not a certified plotter, radar or rescue equipment. You remain responsible for navigation and compliance.
