I’m still getting used to using this but it is intuitive and that is what I need. Thanks for making it easy

Thanks!!

Was the best Nav app available

Sadly I report that I prefer the previous version to the new enhanced release. Why? Because I want an app that is simple and can be used on an iPad mounted on my inner helm station and far enough away so that it’s uncomfortable to reach tiny plus and minus zoom buttons or use fingers to enlarge or reduce the zoom factor. The previous version had an optional zoom slider that could be reached on the screen’s right side and controlled easily by my right hand stabilized by the iPad’s frame. I have requested twice to have this feature added back but to no avail. Also the new version which is also Android compatible just seems to have too many marketing attractants that I should be able to turn off but cannot figure out how. As a navigation instructor this is frustrating to the max. I would love to rewrite this review to be more positive but only will if TZ-Nobeltec responds with some better news.

I tried this before apparently.

Still way too dear in this financial environment. I only need a small area of my local fishing spots. The basic free version is useless. Not even depth contours.

Response from developer

Hello, thank you for your feedback. The free map is based on OSM and does not include detailed nautical chart data such as depth contours. These are available through TZ MAPS, using official nautical chart sources, which require paid licensing. In Australia, the chart area is currently offered as a monthly subscription for the full zone. We understand that some users may only need a small local area, especially for fishing spots, and your feedback is noted. The free version still includes useful tools such as GPS, basic weather, anchor alarm, distance measurements, logbook and user objects. Marie, Product Team

Modification, ajout de données

Bonjour, je vous ai écrit à plusieurs reprises concernant l’ajout de données et de pouvoir laisser à utilisateur de pouvoir le mettre ou bon lui semble au niveau de son écran iPad comme sur Time zéro. Étant donné que nous avons de grands écrans, je souhaiterais pouvoir déplacer à droite ou à gauche les données en graphique comme je le souhaite pour avoir plus d’informations lisibles.
Quand il y aura-t-il avec votre application la possibilité de faire un routage ?

Bonjour et merci d’avoir pris le temps de nous écrire. Nous comprenons votre souhait de pouvoir déplacer librement les NavData sur les iPads à grand écran afin de les positionner où vous le souhaitez. Cette fonctionnalité n’est pas prévue pour le moment. Concernant le Routage, nous souhaiterions échanger avec vous afin de mieux comprendre vos besoins car nous travaillons actuellement sur cette fonctionnalité. N'hésitez pas à nous envoyer un mail à l'adresse ProductTeam@mytimezero.com. Marie, de l'équipe produit.

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.

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

Hello! Sorry to hear that. We indeed discovered some issues in v4.0; developers worked hard (and still work) to fix most of them. Please could test latest version 4.0.3, there is a big chance that your stability/performance issue was fixed. Could you have a try? If you still have the problem, please could you contact Mathieu with this email : productteam@mytimezero.com I will be happy to check the problem with you.

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

Hello, and thank you for taking the time to share your detailed feedback. We also appreciate your loyalty to our products. I’ll address the points you’ve raised. First of all, our mapping service regularly updates satellite images. Unfortunately, for certain areas, we do not have more recent data. Could you please let me know which region is affected by emailing us at ProductTeam@mytimezero.com? Your comment about maintaining the same map view when switching between screens is very relevant. I fully understand that this type of behavior could make checking the weather more seamless. This feature is not currently available, but we’ve taken note of your comment. Regarding the Anchor Screen, our goal was to make this feature more visible and easily accessible by dedicating a specific screen to it. I’m not sure I fully understood your comment about the logbook, which was accessible via Smart Search. Could you please explain this in more detail via email? Finally, regarding the search function and, in particular, activating a route via Smart Search, this is a bug that we’ll be fixing. Sorry for the inconvenience. Marie from the product team

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!
