  • GPS maximum

    Choose if you want to use the maximum GPS mode for better accuracy.

  • Battery

    The app employs the best method for managing the battery.

  • Delay

    The app only can be activated with a minimum of GPS signal for more than 20 seconds.

  • Coordinates

    The screen shows where you set the anchor, and where is the boat.

  • Background Task

    The app works in background, so while it is active you can lock or use other apps.

  • Notices

    Be careful if your iPhone is in silent mode. The app uses the iPhone's GPS if you are navigating on a ship of great length, consequently the app understands that your boat is dragging. The app is conceived and designed for smaller boats without electronic systems.
