User reviews

My new first-line chartplotter.

I’ve used TZ iBoat as my backup chartplotter for a few years, with Navionics/Garmin as my main plotter. Today my wife and I decided to use iBoat for our trip. We are very impressed.

I liked the AIS integration, particularly. The UI is very flexible so I moved a few elements around. The experience was very smooth and completely reliable on this trip.

My wife liked the detailed info that is stored for a route. She was able to find times and locations that she hadn’t recorded even *after* completing the trip.

TZ iBoat is being promoted to be our main chartplotter.

Great Navigation App

I used this app all over the Bahamas and it served me perfectly. I like how it mimics the Chart books which I studied long before using this app.

First impression

I miss being able to insert a point into a course and dragging it to a news spot. The app is not real straight forward as the old Nobletec Nav….. but its similar enough

2nd season

After 15 years of using Navionics I have switched to TZ and had a few issues at first. There are so many options and settings it is easy to get lost. But I am on my second season and I am very happy now. For me it is important that I keep the charts and functionality even once the 12 month are over. Unlike with the previously mention company. This seems to be the case with TZ if you download the charts onto your device, but I did get the subscription for another year anyway.
I use it on my iPad and iPhone. The anchor watch is a good feature…. It would be cool to get the anchor alarm onto the Apple Watch. I also like the weather features very much! I just hope you are not going to over improve every year!

Thank you very much for your feedback and for using TZ! We are happy to hear that you are enjoying the app. Apple Watch integration is not planned at the moment, but we will keep your suggestion in mind. Marie, Product Team

Reste sur ma faim

Que dire de cette version? Elle a le mérite d’exister dommage que nous devions encore payer si comme moi on a la version PC Un avantage sur IPad Pro facile à caler pour contrôler le remps de quitter ou rentrer au port pour anticiper les bouées et les bancs de sable cartes Raster trop vielles choisir la version raster qui ceci dit en passant Acheter pour PC en vecteur la zone Caraïbes 3 jours plus tard on me propose une mise à jour pour 152€.......... mais j.aime la version pc avec routage Pour les enfants c’est très ludique Bonne continuation c’est ma troisième version
