Anchor Alarm will support you during your anchoring. It will also help you find your crew-mates during sight-seeing on the shore.

Notice:
• This application uses GPS tracking in the background for constant measurement of the boat’s position in order to raise an alarm when the boat leaves safe zone.
• This application might send SMS alert (if you explicitly choose to do so) to the user defined receiver, when boat drags off the anchor out of the safe zone.

Its main features are:
1. You do not need internet access to use this application (except of the weather forecast and the remote control of the boat’s position).
2. Check the weather forecast for coming 20 h in place where you are about to anchor.
3. Easy to start anchoring. Just set anchor position. Then set the two-radius zones using blue and red guides. Adjust radiuses by clicking on the map to increase or decrease them. Finally lock your settings (long click “Anchor” button) to avoid further accidental change.
4. Alternatively add anchor or destination position manually and track your position on simple graph without any internet access at all
5. Choose the way the alert is risen. You can choose any of combination of the following:
a. Push notification to chosen contact
b. SMS alert to chosen contact
c. Sound alert on the device
6. CHECK YOUR BOAT POSITION REMOTELY! Now, apart from being alerted, you can also remotely check, at any time, your boat’s position, its anchor safe zone and its track. Simply press “Boat” button in the application and the host application on-boat will reply you with the latest data. Check them any time to feel comfortable about your boat’s position, when being away from it (Watch the film to see the example how it works!).
7. Add as many contacts as you want to list of your crew-mates. Then you can easily switch between contacts to locate them. (Again, watch the film to see this in action! Great and unique feature!)
8. Download offline maps to be sure, that you will be able to use them without access to the internet (note zoom limitations – only 2 levels of zoom, but you can download multiple maps to deal with it).
9. Running in the background makes this application LOW BATTERY CONSUMPTION as for constant GPS monitoring type of application. It uses twice less energy than the competitor’s apps (see the screenshot).
10. Boat’s tracking restarts after spontaneous restart of your mobile (don’t worry, this application is stable). It keeps the track recorded before the crash too!
11. Precise location using all available methods.
12. Choose between imperial and metric units. For the wind speed you can additionally use knots as the unit.

This application runs as a service and due to that it is very reliable. You can completely turn off your screen, even accidentally kill the app (not service), and yet the service would still be working - it would track boat's move and issue alarm when your boat leaves anchor safe circle. Simply re-open application and watch the status and boat's track. However, with the newest Android systems, it might be required to switch off smartphone’s vendor specific optimisations.
You can use this application being completely offline (to save the data bandwidth and the battery energy). Simply set the anchor’s safe zone and start anchoring. Most of the features will be available including issuing alarm as sound alert and/or sending SMS alert.
Application supports languages: English, German, Polish
