Your boat live, even when you are not on board
With the free Signal K plugin your boat sends its position, wind, depth, battery and every other sensor to ClearShip. You see it all in the app and on the web, from the office, from home or from the pontoon.
- Position on the map, with the track you sailed
- Wind, depth, speed, battery, temperatures, pressure and your own sensors
- History of the last 7 days for every reading
- Plugin installed from the Signal K Appstore in a few minutes
Live data is part of the Skipper and Profi plans. The Signal K plugin is in beta. See plans

Anchor alarm
Drop the anchor point, choose the swing radius and go to sleep. ClearShip keeps watching your position in the background.
- Early warning before you reach the radius
- Full alarm the moment the boat leaves it
- Radius from 25 to 150 m, chart overlay on the map
Emergency
Mayday assistant
Pick what happened and ClearShip writes the radio call for you: boat name spelled in the NATO alphabet, MMSI and your current position, ready to read out on channel 16.
- Mayday and Pan-Pan, step by step
- Position filled in from GPS
- Read-aloud button for the call

ClearShip is an aid on board. It does not replace a proper anchor watch, official nautical charts or good seamanship.
Plan at the desk. Tick it off on deck.
The app and the ClearShip web app share the same boat. Prepare the season on a big screen, then do the work with your phone in your pocket.
- Boats, tasks, checklists and logbook stay in sync on all devices
- Changes made offline are sent once you are back in range
- Crew members see the same, up-to-date list

Questions before you install
What does the app cost?
Nothing. The app is free, has no ads and no in-app purchases. A free ClearShip account covers one boat; if you need more boats or crew members, the plans are on the pricing page.
Do I need an account?
No. Anchor alarm, Mayday assistant and all tools work without one. An account is only needed to sync boats, tasks and logbook with the web app and your other devices.
Does it work without internet?
Yes. The tools run offline, pinned documents are stored on the device, and anything you change is synced as soon as you are back online. Weather charts and new map areas need a connection to load.
What do I need for live data?
A Signal K server on board (for example on a Raspberry Pi), the free ClearShip plugin from the Signal K Appstore and a Skipper or Profi plan. The plugin sends every 60 seconds by default.
When is the iPhone app coming?
We are preparing the App Store release. Until then, the ClearShip web app runs in Safari on your iPhone.
Why does the app want my location in the background?
Only for the anchor alarm, and only while it is armed. The position is processed on your device; logbook positions are synced only if you use an account.
Which languages are available?
English and German, each with a light and a dark theme.
Put it on your phone before the next trip.
Installing takes a minute. Setting the anchor alarm takes two taps.
