1. 5/5Too many problems

   I tested several Mac apps and this one was the best... last year. This year too many problems and yes I am using the same phone. The icon is too big and does not point on your heading. Some areas of downloaded map are just blank. Very poor when zooming in or out.

2. 3/5Glitches galore

   I’ve had this app for 16 months and have kept it on my IPad as a backup to Navionics on my chartplotter. It’s in a nutshell just a GPS overlay on NOAA charts. You have to select the areas on the map that you would like to download, and even after downloading the screen will go half blank randomly while underway. Most chart downloads are dated info, and zooming in for detail the chart generally just disappears, leaving you to find the bottom with your keel. For all intensive purposes I guess it’s ok as a backup, but nothing compared to Navionics, and cannot safely rely on it for navigation. If your looking for an accurate, up to date, and reliable product, this isn’t it.

3. 2/5Good potential, needs work

   Using this app for the first time, I found it to be reasonably user friendly, but some features were difficult or impossible to use. I am writing this as a review because the “support” button does not work. 1) The boat icon’s direction is tied to the compass, not the actual track. As you move the phone, the icon turns. It is only correct when the phone is exactly aligned with the center line of the vessel. 2) Tried using the route feature with mixed success. Creating the route was straightforward, but when trying to edit or select a route, the list appeared to have a font of white on white. Same with other fields in the app such as editing a waypoint name. Finally had to give up on routes and use “navigate to point “ repeatedly. Used on an iPhone 8. This app has potential, but is not at the quality of a paid app yet.

4. 1/5Wish it worked

   Downloaded a used the two week free trial. I liked it for the most part. Once the trial was over I subscribed to continue using. It failed to work and kept trying to sell the subscription (I had paid for a year through iTunes). I tried logging out and logging back in and received network errors and time outs. iPad turned off and on, still failed to login. Sent a message to support and haven’t received an answer. Deleted and canceled membership. Potential is lost.

5. 4/5Great tool to use while sailing

   I downloaded the app prior to our first coastal cruising venture on our Catalina 22 sailboat. I found it much easier to read than our handheld Garmin unit. I’m still learning how to use all of the features and plan on visiting the full website for full instructions on how to use all of the features.
