I actually navigate using the app. It's great for using in the dingy when setting crab pots. I like to set them at 40, to 50 feet. Follow the depth soundings, better than using the sonar. Very good resolution at multiple zoom levels. Not quite as good as my Nobel Tech or my C-Map NT Superwide +, but then it didn't cost over $5k either.
App is based on old contour maps and is not as accurate compared to Navionics. Also app should be labeled as a trial version and not free. App locks most features after a week and spams you to upgrade. Upgrades start at $20 and go up from there. Do yourself a favor and spend the extra money on a better app.
I had previously rated 5-stars and had several friends download/buy. Recently, support has declined and forced to re-purchase maps, or deal with continual annoying messages. Shame! Map updates should be provided, annoying message at entry only and support needs to be responsive.
Charts east of Helsinki did not exist in the pro version. Despite numerous emails, there was no support from their support email. Thus I do not recommend this product. Buy the competitor. I purchased Navionics and it worked ok.
excellent but should be $no more than $15.00 so everyone can buy plus you cant use continuously becouse battery life on mobiles so little drains battery i
Downgraded from 5 stars. It is a great app but now it's past it's trial period it is stuck on 'auto-follow' and won't let you close it without paying or forcing the app to stop!
