Awesome!!!

Easy to use and very accurate. Great backup if you ever have a problem with your house electronics and TZ Maps is incredible.

This has been a great App

For the first time using my iPad on a 70 mile trip from New Hampshire up the coast of Maine, this along with paper charts found our way home. Easy to use and accurate. Now several years later this app is still my favorite to use on trips with my sailboat. I have finally reduced Nav apps to one.

I love this app! But… depth chart numbers need to be able to be read, easier. Suggestion: make depth chart numbers, a contrasting color, and, when zooming in, make the number enlarge as well. Thanks for the great product!

Bad sat image

Don’t understand how an app that cost this much doesn’t have a better satellite image. So many free apps out there with better sat images

Needs improvement

The program needs to allow routes to be combined into a trip plan.
