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

Next level navigation aid. I back it up with Garmin 7600. TZi easily is better! Buy it for 15$..

Amazing app

I was very pleased to use TZ nav software. I had to quit Navionics-Garmin because they shut me down for an update. I can not update software when I am offshore. I use a Bluetooth GPS antenna to navigate with TZ on my I-Pad. It is a better product and a better buy. With TZ I can select the right chunks of the global grid that I want. Navionics wants me to buy much larger chunks of the globe for far more money. I also like seeing a constantly adjusted ETA on the distance measuring tool. Now I have no fear of being locked out of my software. Charter boats have chart-plotters that may be unfamiliar or “salty”. I can always rely on my I-pad for nav or an alternate zoom. Peter Shearer

I really love TZ iBoat

Good

I really like this app!

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

TZiBoat is just a terrific app. Its features rival those of of chartplotters. I love it!

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!
