DISCOVER THE ONLY BOAT APP YOU NEED AT SEA!
TZ iBoat is the most advanced boat navigation app on the market, it gathers all the features necessary for safe maritime navigation:

No more wasted time searching your map for a marina; enter the name and it will be automatically located on the map.


- SMART ZONE: Set up an alarm for when your boat enters or leaves specific areas on the nautical chart (e.g., restricted areas). Configure the types of affected to suit your preferences. Display NavData to see a list of all zones in which your boat is located.

Horrible map accuracy, sleek app.

Bert Wahlberg on

I really want to love TZ iBoat, but I can’t safely use it. Compared to the Navionics maps and app, it’s simply not a viable option. Shallow Tampa Bay, Florida is my main sail area and this is routinely off by 5+ feet where it matters most. It has nice features. I bought it for the auto pilot integration, and possibly radar module down the road.

Phenomenal tech

TZ has made our life much simpler navigating our boat. We have weather, current, tide, AIS, anchoring info all in one place along with the most advanced mapping and planning system.

Very Impressed

EchoWhiskey on

I have tried all of the sailing apps out there and it’s hard to find one that’s a good balance of functionality and price. I am a long time user of a different popular app, but decided to give this one a try and have been surprised by how much I like it. There are a few features that I wish it had (a better management system for saved tracks) and the companion laptop software is absurdly priced, but the app is worth trying and spending the money for maps. I still haven’t managed to get it connected to Furuno network on the boat I sail on (better instructions on making the network connection work would be nice), but the maps are very nice to view and all the interactions are intuitive and easy.

Very happy

I’ve just recently downloaded this app. I have been using another app based navigation system solely for the the last ten years of cruising all over Central American and South Pacific. The app I was using failed, that’s when I realised I had no easy backups. After making land fall I spend many hours over many days looking at, reading about and downloading all the marine offline navigation apps w/ AIS overlays. I settled with TZ and after an adjustment period of getting acquainted with the new system. I can say I’ll keep to other app for a back up, BUT TZ is sooo much better and fun to use!!!! It has everything I need and more. Thanks for such a great product!!!!

No autoroute function?

JoeCirig on

I do like and use the software for certain features, but no automatic route creation? Seems like that’s a pretty important feature if you want to consider using this app as your default navigation software. I assume it’s coming, but until it does, I’ll stick with Navionics

Maps are nice, but live tracking could be better.

a duo lingo user on

I subscribed to this thinking that it would be a great backup for the chart plotter on mu boat. I also wanted to use it as a chart plotter for my dinghy when off on excursions. The maps really are very good, your position does not update very well while in motion. So it is really kind of like having the old school paper maps on board. Which is still useful. I am using this on an iphone 13 if that makes a difference.

Nothing but “oops, something went wrong” error page.

How to make it it better

Alejandrorrrrhhhhh on

Automatic routes would be good and easier intregation with chart plotter to share routes and navigation info
