Saildays

Your sailing logbook writes itself

Saildays records your track and logs every tack, gybe and course change with the time and position. You sail, the app keeps the log.

Free Android app. No account, no ads. Your trips stay on your phone.

What it does

Logbook with the day's timeline and a map preview

Records the trip for you

Tap Start recording when you cast off, and Saildays records your track even with the screen off and without signal. Every course change of 30° or more goes into the log with the time and position where the turn began, and stops and departures are suggested in a notification.

Note with wind, manoeuvre and photos

Everything else in one tap

Engine, sails with reefs, anchor, marina, mooring buoy or shore lines, each with one tap and your current position. Notes take wind, manoeuvre, dictation and photos, and there is a radio log and a man overboard button that points you back to the spot.

Map with the track and OpenSeaMap marks

A real sea map

Your track on OpenStreetMap with OpenSeaMap seamarks, coloured by sails and engine, with every log entry on it. Areas you have viewed stay on your phone, so the map works offline too.

End-of-trip summary with export

Export when you need it

A finished trip goes out as a ZIP with a GPX track for any map app and a JSON file with the whole log and your photos. Send it to Google Drive or by e-mail, or keep it on your phone.

How it works

    Start recording

    Tap Start recording when you cast off. A notification shows that recording is running.

  3. 3

    Look back

    Browse the log day by day, see the trip on the map and export it when you are home.

Private by design

  • Your trips stay on your phone. There is no server and nothing is sent to us.
  • No account. No sign-up, no e-mail, just open the app and sail.
  • No ads, no analytics, no tracking. And it is free.

The only thing downloaded from the internet is map tiles, from OpenFreeMap and OpenSeaMap. Details in the privacy policy.
