The app can alert you to the approach of large vessels.

This app is useful for non-equipped-AIS- vessel like small ships. When you are sailing on the sea within “service area” with small ships, this app alerts you to the approach of large vessels which are sending their own AIS information to you even if you are working or fishing and so on. Especially, “AR” function is useful for you when you are in the night and/or low visibility due to dense fog.
We will regularly expand “service area” of AIS. You can confirm the latest on “J-Marine Cloud” website or this app’s “service area” menu.
・This app alerts you with sound and vibration, if the large vessels are into the “Guard Zone”.
・”Guard Zone” range is up to 5nm.
・The AIS information is layered on the camera view in using the “AR” function.
・The AIS information is regularly and automatically updated around yourself about 5.4nm.

【New function】
・Adjusting of display brightness for night mode.
・Displaying the estimated 5 minutes later position and course from the AIS based information.
