Works way better than I thought!!

The noaa charts are great. Its intuitive, tracks very well. Since this is the 3rd gps program for sailing on my iphone, I know what I want from the App. I was able to set waypoints and plot a route pretty easily. When you turn on tracking it works really well. Like showing details of us circling to Anchor and later motoring on a dingy to shore and back. The only caveat is if you forget to turn off the tracking when you get home it will continue to track and delete your previous tracks when the memory becomes full. One of the interesting features is the ability to email a copy of the chart with your track and current location straight off the app to your friends or to post on Facebook. I havent tried it yet but its an interesting feature. The only thing that I had spent time figuring out was how to change the course heading and bearing from true to magnetic. If you click the "help" button, its got a lot of details on how to use the app. And of course you know that because it relies on the GPS on your phone you dont need to be connected to your 4G or Wi-Fi. Just remember to download the charts before you leave home. Im giving it a four star, but it should actually be 4.5. When I use the app again I will further update. All the other crew on the boat were also very impressed and said they are going to download the app.
