used to be dope even worked on devices without cellular data

now it says I have to purchase to get a map, even tho i already did, then i try to
purchase and it says nothing is available. I try to restore purchases and it’s a UIButton with a broken target, it does nothing but further annoy people trying to use the app in even the most basic capacity.

please fix this a nautical gps app is useless without the charts.

Crashing

Have had this app since 2013 use it a lot as a back up GPS even 60+ miles offshore fishing. It’s very accurate. However, recently started “crashing” a lot after a few minutes of use. Please fix the bug.

Get a Navi

This app did not even have my area to download. It’s horribly user unfriendly. Save your money.

Great app! Better than my Garman.

Great app

I can't believe how much I use this app

ICW night navigation made easy. Thank you for the assistance.

Great support

The support for this app is amazing. You get a response right away and it's always helpful. As a non technical person I'm delighted to have great support.

Great app for iPhone but...

Does not have all the features on iPad. Especially lacking is the "follow" feature which is the highlight of this app imho. Works great on phone though. The vector chart for the northeast seems to be a little off. At least on my iPhone and iPad it is always about 30-50 feet off from reality. Not an issue in open water naturally but when you're in a tight channel it can be a little nerve racking. Not a bad app all and all though.

Great buy

Great app. Using it right now on my travel down the Chesapeake. Has speed, depth and I can download tons of noaa charts without additional charge that are accessible offline. Also one thing I like is to place a waypoint when I anchor. In the night if I am worried I am drifting I check this app to see where my gps is versus the anchor. That is super useful in my book.

Downloaded and used on a recent trip to the FL Keys

Very useful in guiding through the keys channels. Once you have a map and want to plot a route this is very useful. Takes a little getting used to but got the job done. Harder to use on iPhone due to screen size.

Very handy app

I was down in West Coast Florida on a vacation and decided to rent a boat for a few days. Didn't really know my way around so I took a chance on this app and it turned out to be much better than expected. I was able to plot a course the night before to a likely looking redfish hole and really got into them the next day. Love the auto track feature. It shows an arrow on the screen that shows where you are headed. I used it on my phone that day but since then I have installed on my iPad.

Replace your plotter

Great app for boaters and sailors. I use it on the phone and on my IPad.

Captain Rob

This is the most useful app I have ever used for navigation. Waypoints, distance, and record and auto follow work great! Then go back and see exactly where you've been and your speed throughout! Highly accurate charts and charts for all you needs. I have it both on my iPhone and iPad. Handheld GPS for those foggy days can't be beat anywhere for the price! Highly recommended!

Accuracy

I like the accuracy of my GPS location on the map.

Clean

Very clean, nice features, easy.
Good job!

Don't

I just wasted 15 bucks on this! No key to map symbols and no response from support. Map quality lacking.

novice navigator

This app is full featured and remarkably we'll documented. The only thing I couldn't figure out was explained well and promptly by support.
I think this app is great! I would benefit from availability of even more maps.

Not good for Western Rivers

Not worth the data to download it. Mississippi River charts are horrible looking. Header line is to big. You have to open the chart where you are at. I don't know if it will automatically open the next one or not because I can't stand to look at it for that long. You'd be better off using a paper chart from 1992 and Google maps.

Decent app

I got the impression from the app description that you could see a map that simultaneously provides all of the data that's provided by the app -- location, depth, current tide and tide forecast. Unfortunately, it's not the case. However, it does have the info you need -- it just takes a little bit of navigating through the app and head-math to get to it.

Decent app

Hard to figure out at first. Once you figure it out it is very useful.

Mr

Works great for me.
