Awesome App

Super easy to operate

Wonderful surprise

Just installed TZ pro 2 months ago. Added TZ IBoat at same time. I am thrilled by the integration of the two systems. I plan rout on the IPad and they are uploaded to TZ pro. Activate a rout on any device and the rout is active on all system devices. Highly recommended product.

Unkomplizierter Urlaub

Dank TZ iBoat ein völlig unkomplizierter Törn und Urlaub rund um Sizilien und der unzähligen Inseln und Buchten. Habe definitiv meine künftige Navigationsapp gefunden! 🤗

Problème majeur de sécurité en mer : l’affichage superposition instruments/carte ont été supprimé

Bonjour,

Nous utilisons TZ iBoat dans un cadre de navigation réel et de formation de skippers, y compris de professionnels.

La version 4.0.3 semble avoir supprimé ou rendu inaccessible l’affichage simultané de la cartographie et des données de navigation essentielles (COG, SOG, cap, position, profondeur, vent, etc.).

Si tel est le cas, cette évolution constitue pour nous une régression majeure.

L’intérêt même d’un logiciel de navigation est de pouvoir visualiser en permanence la situation du bateau sur la carte tout en disposant simultanément des informations de navigation nécessaires à la prise de décision.

En mer, il n’est ni pratique ni souhaitable d’avoir à basculer continuellement entre un écran “Carte” et un écran “Instruments” pour obtenir des informations qui doivent être consultées ensemble.

Cette organisation ne correspond ni à l’usage réel de la navigation ni aux principes de sécurité que nous enseignons.

Aujourd’hui, nous formons des plaisanciers, des chefs de bord et des professionnels. Nous avons besoin de pouvoir afficher simultanément la cartographie et les données de navigation. Sans cette fonctionnalité, il devient difficile d’envisager l’utilisation de TZ iBoat comme outil principal de navigation et de formation.

Pouvez-vous nous confirmer :

* si cette fonction existe toujours dans la version 4.0.3 ;
* comment la réactiver le cas échéant ;
* ou s’il s’agit d’une suppression volontaire de l’interface.

Frustrating

Keeps going into 3D view when I scroll or zoom, despite 3D settings being turned off. I don’t ever want 3D. Don’t remember the older version doing this.

New version glitchy, keeps shutting down

I’ve used tz iBoat for years with great success. Once I installed the latest version on 8 June 2026 it has become incredibly unstable and shuts down frequently. Really not even usable. I created a service ticket. Hopefully problem can be resolved quickly but until it is I suggest avoiding the new version

Update 25 June -

Ver. 4.0.3 has resolved the problem. Thanks for fixing it so quickly

This is a great app, but…

I’ve been using this for a few years professionally for deliveries and charters throughout the Caribbean. I’ve always been very happy with its functions and quality of charts, integration of weather and what I think is the best anchor watch available period. My only complaint until now has been that the satellite overlays are very very out of date, 7-8 years in some cases. However the new version is clunky and very frustrating. Weather used to be a simple layer you can turn on or off, but now is a separate tab, which doesn’t open on the same location as where i might have been on the Navigation tab, so then i have to move the chart again to were i want to see the weather. The Anchor tab seemed un-needed as it was just a button, so why make a tab that has to be set up with the layers you want visible. The logbook was always available in Smart Search so also seems like an extra layer of UI for no reason. My biggest complaint is that I can no longer use Smart Search to find and activate a route. When choosing a route from Smart Search the chart zooms out, but the activate icon is greyed out, and it doesn’t show the route unless I click on the start waypoint, but I have hundreds of routes and many share start waypoints, so then i have to change the settings to show arrival waypoints, find the arrival waypoint on the chart, and then i can click activate. What used to take 5 seconds now takes 5 minutes. I love many things about this software and the PC based TimeZero, but am not happy with how clunky version 4 is

Best nav app on the market!

I’ll be using this app for r2ak 2026 and its the full package. Weather, tides, ocean conditions, ais, offline navigation, and multiple charts it has it all. All with intuitive user interface when on the go. And to top it off, the customer service is wonderful. If you wonder which app is worth the money, this is the ONE!

Very poor

Completely unusable - glitchy, unstable, frequently crashes and fails to draw cartography. Extremely difficult to understand why this has been released as an upgrade!

Constantly improving!

This company actually cares about improving the app for the user. A while back I wrote a lengthy email explaining all my issues and frustrations with this app. Instead of brushing me off with a copy paste apology I was asked for a list of things I’d like to see changed. I then got follow ups for clarification on some of those changes. It’s taken some time but many of issues I and I’m sure many others once had with this app have been addressed. This kinda of attention to improving will definitely be affecting the next MFD purchase that goes on my boat. Thank you for not being satisfied with good enough.

Perfekte Navigation

Läuft sehr gut. Auch in Kombination mit der TZ Software am Bord PC. Bootsdaten per WIFI erhalten läuft problemlos.
Einzig das Wetterrouting für meine erstellten Route würde ich mir in der App wünschen. Das funktioniert aber am Bord PC auch problemlos.

Response from developer

Guten Tag, vielen Dank für Ihren Kommentar! Die Routenplanung ist derzeit in der TZ iBoat-App nicht verfügbar. Wir haben bereits mehrere Anfragen zu diesem Thema erhalten und prüfen derzeit die Umsetzung dieser Funktion. Um Ihre Bedürfnisse besser zu verstehen, zögern Sie bitte nicht, uns unter ProductTeam@mytimezero.com mehr darüber mitzuteilen. Marie, TimeZero-Produktteam

Position Lost Alerts

Constant position lost alerts. Pretty much useless.

Great App!!!

I love this app and all its features. Very useful and kinda simple to use. Advanced options are great. Customer service is excellent and quick to respond to questions!!! I tell everyone bout it.

Un véritable compagnon

Oui un véritable compagnon de navigation facile à configurer avec mon réseau nmea2000 la cartographie en location pour le moment à prix raisonnable.
Le seul reproche il ne produit pas une polaire comme d’autres logiciels moins cher que TZ .

Excelente

Este software es muy cómodo y sencillo de usar, lo que lo hace amigable para navegar.

Nice

Love the app good information and always on hand.

Excelente

Muy buen programa de respaldo a tzt3. Muchas funciones y sirve para navegar sin plotter
