It works

Withdrew a bad review ... It is slow to scroll on an iPad but if you are sailing well you don't go that fast .... So it is a good app

Now ‘embiggened’ for iPhone X!

With the app now making full use of of the larger screen of the X iPhones, with the added weather detail, it’s even better! With AIS plotted as well, this app has much to offer with charts fairly priced too. I’m looking forward to seeing what’s going to be added next.

Hi Mark, Thanks for the great feedback. We have listened and the new version of SeaNav now supports full screen on the iPhone X. Its a free update. The latest version also adds an amazing animated weather view showing wind, waves, rain and pressure out to 10 days time.

Initial set up problems had me struggling with this app and I’d just about given up until contacted by the developer who got me up and running. Great customer service and I’m going to enjoy using this new found wealth of information in the bays and inlets of the Western Isles. Thank you Steve Bennett, much appreciated.
