Three plans, and the dividing line is simple: Free is a complete logbook on one device, Sync adds the cloud and the documents, Share adds the instruments and the sharing. Prices are on the pricing page; this article is about what you get.
On every plan, including Free
- Unlimited log entries and passages, with no time limit
- Crew, animals on board, maintenance and inventory
- The map, including the offline tiles you download yourself
- All 16 navigation calculators, celestial ones included
- Summary and statistics, full-text search, the VHF reference and the safety checklists
- Local backup as a ZIP, and CSV and GPX export
A Free account is not a demo. It is a full logbook that stays on the device you keep it on.
What Sync adds
| Feature | What it means in practice |
|---|---|
| Sync across devices | The same logbook on the chart table, the iPad and at home |
| Browser and home-screen version | On Free these show an upgrade screen; the desktop and iPad apps do not |
| PDF exports | Logbook, ship dossier, crew list, customs declaration, maintenance log |
| GPS position capture | One tap instead of typing coordinates; manual entry works on every plan |
| Photos and documents in the cloud | Images reduced to about 1 MB and at most 1920 px |
What Share adds on top
| Feature | What it means in practice |
|---|---|
| NMEA live data | Position, speed, course and wind from your instruments — desktop app only |
| Shared passage links | A private link for family or crew, with layers you control per link |
| Full-resolution photos | Applies to photos added from then on; earlier ones stay reduced |
Two things worth knowing before you choose
NMEA needs the desktop app. Reading instruments over NMEA 0183 works on Windows, macOS and Linux — not on the iPad and not in the browser. The Share plan does not change that.
On Free, the logbook lives on your device only. Nothing of it is kept on our side, so there is nothing to fall back on if the device fails — your backup is the ZIP you make yourself.
Every account begins with 30 days of Share: Your 30-day trial. Changing or cancelling later: Managing your subscription.
