User Reviews

Reviewers consistently praise TZ iBoat for being easy to use, especially on an iPad, and for strong route planning, reliable navigation, and a feature-rich toolset that rivals chartplotters. Many cite its backup navigation role and responsive customer support. A recurring caveat is the limited access to satellite imagery within the app, with some noting poorer image options than free alternatives. Overall, TZ iBoat is a capable, value-oriented marine navigation tool for planning and monitoring voyages, with room for improvement in imagery availability and a few feature gaps.

Pros

Easy to use and intuitive interface, especially on iPad.
Strong route planning and waypoint management capabilities.
Reliable and accurate navigation with good backup options.
Rich feature set that rivals chartplotters (weather, tides, currents, layers).
Helpful, responsive customer support.

Cons

Limited access to satellite imagery/quality within the app.

Recent reviews

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

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 My only complaint until now has been that the satellite overlays are very very out of date, 7-8 years in some cases.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

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!
