Boatie Logbook
A sailing logbook built for real passages. Offline-first core logging, with a time-limited preview on every new download so you can try before you choose a plan.
Features
Boatie Logbook is a sailing logbook built for real passages. Start the log when you slip lines, capture weather and position at each watch change, review the track afterwards, and export a clean PDF for the boat’s paperwork, insurance, or certification.
Designed offline-first. Core logging works without an internet signal — because that’s what cruising is actually like. Every new download includes a time-limited preview before you choose a plan.
