You need to add a function that allows you to enter a waypoint lat and long - so the user could determine distance and bearing to a particular location. I cannot find an app that does that. All the new apps emulate chart plotters. What is need is to be able to find distance and bearing to a particular spot (for setting up sail boat races for example). Also such an app would be useful to make sure the anchor is set.

This is a pretty neat app. It seems to work quite well though I am only armchair testing as well. Besides the navigation utilization, this app could readily advise one of whether they are being knocked or lifted when sailing a course. The compass does seem to be nicely dampened as well. I agree with 'Nobstacle' that the ability to download charts for an area, and thus be independent of data (when at sea) would be great. I'd only pay a few times the cost of the app for that function though. Oh, instead of a N displaying next to the bearing when in True mode I'd like to see a "T". Can't wait to try this at sea.

Although I have only armchair tested this app, it works as advertised. The augmented reality camera/compass is a nice feature which should be useful on the water especially with the ability to zoom. I don't see how the compass rose map feature will be helpful on the water without a data connection. It would be great if it could read locally stored ENC or raster charts. I'd pay 10 times the $2.99 price if it could do that.
