i-Boating: GPS Nautical / Marine Charts - offline sea, lake river navigation maps for fishing, sailing, boating, yachting, diving & cruising

Great app for keeping a list of coordinates and seeing where they fall on a chart. Takes awhile to get use to inputting numbers

Very easy to install new maps. Works great on my Asus laptop.

Very easy to use. Make sure to download all grid cells to avoid pixelation.

I downloaded the app and the first free tile. It looked like a pretty good app so I purchased (in-app) the United States and proceeded to download the remaining tiles in my area. A progress bar came up showing the progress and then it stated that it was compete. Ever since then it appears to overlap scanned map fragments that are only visible at certain zoom levels. I only get bits and pieces (totally incomplete - I can't even get an entire pond). The Android app is great, I love it, but until this app is fixed I want my money back.

This app does what it sets out to do very well, except where NOAA charts cover an area of fresh water lakes. Those lakes do not even show, nevertheless have depths, etc.

Works great with our ubloc USB GPS.
