I work on ships and enjoy following along the chart on my phone, my only issue is when there is no signal it stops tracking. I assumed it would use my phone's GPS? Anyone know if it's just me, or does it require a signal? Other than that can't beat the price, just takes awhile to figure out if you're not a techy, obviously like me

New to sailing and chart plotting, but I've been pleased so far. On a race last night, I navigated and tracked our sail while another on board with Navionics ended up with an incomplete tracking log (iOS issue with app sleeping it seems). I'll update review as I use more features. Oh, and I was able to export GPX of the sail for importing into SailTies. Overall the app seems clunky in places but powerful.

The latest update appears to have removed the option to display my stored US RNC charts. As the ENCs don't show inland waterways (like the S Gulf Cove entrance to the lock and route to the four boatyards near Placida, FL), I'm forced to transition back to Navionics. I wish the Android version had at least the same capability as the Windows version, as I'm not going to keep a laptop in the cockpit. Additionally, the celestial nav tool won't run in Android.
