Great App
I bought INavX when I purchased a DigitalYacht IAIS unit in 2013. I used the app in conjunction with my onboard Raymarine chart plotter and radar and used this app for AIS information. I us editor the remainder of my cruise beginning in Mobile and along northern Gulf coast down to Indian Key, then returning to Kentucky Lake spring if 2014. It was very valuable tracking AIS targets and foe general navigation backup.
