### 4/5 — Very nearly 5 Stars. Recommended.

*2019-01-08*

Useful app. Could be improved further of coordinates could be entered in format Degrees Decimal Minutes as opposed to just DMS.

### 5/5 — Great training app for boaters and cruisers

*2017-06-30*

This app is exceptional tool for honing your boating skills while not on the water (like those cold winters up north). Safe boating and piloting courses can really take advantage of this app.

### 5/5 — Suggestions!

*2016-05-29*

Many tanx for your good program.
As a marine officer inform you, mostly we need a program for gyro error. Final calculate DEVIATION. If mention this part your program will be tje best.
