The app is simple and accurate. I had dragged twice in one hour on a new-to-me boat and ground tackle. Actually the 6th time with this boat. It was time for peace of mind so when I had finally set the anchor, I downloaded the app. Totally happy with the performance. Now it's time for a new anchor.

Non cellular iPad connect to DataHub and pulls in data from the NMEA 2000 system. Streams boat information to my phone when I’m not on the boat. So far, the best anchoring app I’ve found for the type of information I wanted when away from the boat.
