In routes feature there is a world map: it isn't a nautical chart and is not for use as a saling chart, but as a simple general means of showing the courses through the water on earth, this map isn't for navigational purposes.

Ratings and reviews

I have made some purchases for additional functions but after few days it was automatically cancelled without my permission. Although refund has been made but i think you should sort it out. I installed the pro version i hope it won't cancel my purchase again.

Being a Navigating officer always wanted an Offline App to work through Course n Distances. ALL I CAN SAY IS THIS IS THE BEST APP related to my Profession Simply Put Lat Lon Calculate Dist and start sailing... Basically does all what U need while being offline at Sea.. Keep it up Thx. They should have added an Extra Star .....👍👌👌👌👌👌

Trying to figure out a route to a place approximately 5 nautical miles away. And it told me it would take three days to get there. I really didn't have to use it anymore than that to know that I would soon be deleting it.
