Ratings and reviews

This is a good app that I have been using for while. It is generally stable. Support is a bit tricky, the support forum doesn't appear to have been updated for years. I was unsuccessful registering and getting activation emails. The Android version needs the ability to delete chart files. You can't do this through the Android file browser anymore unless your device is rooted. I downloaded unneeded MBtiles and can't delete them. They are large. Only option appears to be uninstalling.

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.
