Excellent customer services

I few months ago, I found an area in the Chesapeake that pulled up the wrong chart. When I sent the developer an email, he acknowledged the bug quickly, and indeed in a week or two the correction was included in the next revision! I am a very satisfied user.
By the way, it may not be clear that NOAA charts are all included at no extra charge. Download most of your desired charts using wifi to avoid data usage.

I could not get 5.0 to work on one device, so I didnt update the other. I replaced my phone, so I had to go with 5.0.3, which seems ok on an iPhone SE.
Still the best!
