Entre l’île d’Yeu et la Bretagne sud, à bord de Sweetie VIII, notre partenaire Ewan Lebourdais, photographe maritime et Peintre officiel de la Marine, partage son expérience de navigation avec TZ Professional et TZ iBoat.
Face à une météo incertaine, il raconte comment la comparaison des modèles météo, le routage et les données du bateau l’accompagnent dans ses décisions en mer, tout en laissant une place essentielle au jugement du marin.
« Les instruments changent. Le sens marin, beaucoup moins. »
Découvrez son récit complet, entre navigation traditionnelle et technologies modernes.
For years, Android boaters searching for the best marine navigation app usually found the same names: Navionics, Aqua Map, C-MAP, Savvy Navvy, OpenCPN, iNavX. One important name was often missing from Android app lists: TZ iBoat.
That absence was largely a platform problem, not a capability problem. TZ iBoat was already known by many iPhone and iPad users as a powerful marine navigation app, but Android users could not evaluate it alongside the leading boating apps available on Google Play.
TZ iBoat is now available on Android for the first time, bringing TIMEZERO’s mobile marine navigation experience to Android phones and tablets. With nautical charts, route planning, marine weather, Rain Radar, tides, AIS, NMEA connectivity, mooring tools, sport fishing features, offline access, and a redesigned interface, TZ iBoat now belongs in the conversation when boaters compare the best marine navigation apps for Android.
Quick Answer: Is TZ iBoat One of the Best Marine Navigation Apps for Android?
Yes. TZ iBoat is one of the most complete marine navigation apps available on Android, especially for boaters who want more than a basic GPS chart viewer.
TZ iBoat is a strong choice for Android boaters who want the best charts and features in one app. It is especially relevant for sailors, powerboaters, coastal cruisers, fishermen, and Android tablet users who want a marine navigation app that feels closer to a chartplotter than a simple boating app.
If you are comparing Android boating apps like Navionics, Aqua Map, C-MAP, Savvy Navvy, OpenCPN, or iNavX, TZ iBoat now deserves a place in the comparison.
Why TZ iBoat Was Missing From Android Boating App Rankings
Many of the best boating app rankings are platform-specific. If an app is not available on Android, it cannot realistically be recommended to Android users. That is one reason TZ iBoat was historically excluded from many lists, even though the app offered advanced capabilities on iOS.
With TZ iBoat 4 now available on Android, that barrier no longer applies. Android boaters can now evaluate TZ iBoat alongside the major marine navigation apps already available on Google Play.
This matters because TZ iBoat is not simply a chart viewer. It is designed as a complete marine navigation app for boating, sailing, cruising, and even sport fishing.
What Android Boaters Should Look For in a Marine Navigation App
The best marine navigation app for Android should help boaters plan, monitor, adapt, and stay aware of changing conditions. A serious boating app should combine navigation, weather, safety, and onboard data in a clear interface that works underway.
Accurate nautical charts and offline chart access
Route planning and easy coordinate entry
Marine weather forecasts, Rain Radar, and storm awareness
Tide and current data
AIS target display and NMEA instrument connectivity
Anchor Watch, mooring tools, logbook, and trip features
Fishing and oceanographic data for offshore planning
A clean interface for Android phones and tablets
TZ iBoat brings these tools together in a redesigned Android experience built for real boating conditions.
How TZ iBoat Compares With Other Android Marine Navigation Apps
Different boating apps are built for different users. The best app depends on how you navigate, where you boat, and how much functionality you need. The key point is that TZ iBoat now belongs in the same comparison set as other major marine navigation apps.

What Makes TZ iBoat Different on Android
TZ iBoat 4 is important because it gives Android users access to a more complete mobile navigation app. The strongest differences are not one isolated feature, but the way charts, weather, onboard data, safety tools, and fishing intelligence work together.
A Redesigned Interface and the TZ Bar
Marine navigation apps can become difficult to use when charts, weather, tides, instruments, routes, and alerts are crowded onto one screen. TZ iBoat 4 addresses this with a cleaner interface and a new navigation system called the TZ Bar.
The TZ Bar gives quick access to dedicated screens for major functions, giving key tools their own space while keeping the chart clear and readable.
Marine Weather, Rain Radar, Tides, and Offline Access
Weather is one of the most important parts of safe boating. TZ iBoat 4 includes a dedicated Weather screen that helps Android users review conditions, compare weather layers, and understand what is happening around their navigation area.
TZ iBoat also includes Rain Radar in the U.S. with extended coverage and lightning data, helping boaters identify storm activity before it affects a route. When downloaded in advance, key data such as charts and weather can also be available offline, which is important for navigators operating without constant cellular connectivity.
AIS and NMEA Connectivity for Onboard Data
Many boaters want a mobile navigation app that can work with onboard instruments, not just the phone or tablet GPS. TZ iBoat 4 includes improved NMEA connectivity, making it easier to connect, manage, and prioritize navigation data sources.
Depending on the onboard setup, TZ iBoat can work with NMEA gateways, NavNet MFDs, TIMEZERO Professional or Navigator, and the device’s internal GPS. The app also makes it easier to view connection status and data validity, helping boaters understand where their navigation information comes from.
Practical Tools for Real Boating Conditions
TZ iBoat 4 also adds practical improvements for use underway. A dedicated latitude and longitude keyboard uses large keys and helps reduce input errors by enabling only valid options at each step. Users can choose coordinate formats during entry, including decimal degrees, degrees/minutes/seconds, or degrees and decimal minutes.
This is useful when creating marks, editing waypoints, entering object positions, or adding a location received via VHF, phone, email, or another navigation system.
SportFishing and Oceanographic Data
TZ iBoat is also a strong option for sport fishing users. With the Elite plan, users can access ocean layers such as sea surface temperature, chlorophyll, sea surface height, currents, and bathymetric charts.
These layers can help offshore anglers understand conditions, identify promising areas, and make better planning decisions. For Android users searching for a fishing navigation app, offshore fishing app, or marine navigation app with oceanographic data, TZ iBoat should be on the shortlist.
Plans for Different Types of Boaters
TZ iBoat 4 includes plans designed for different levels of navigation need:
Essential: for onboard instrument connection, live AIS display, and autopilot integration through Wi-Fi NMEA.
Premium: for Essential features plus advanced weather, Rain Radar, multiple weather models, comparison tools, and offline weather.
Elite: for Premium features plus oceanographic layers, including sea surface temperature, chlorophyll, sea surface height, and currents.
Free users can still access useful core tools, including Anchor Watch, basic weather, offline weather access, trip management, and Smart Search.
Who Should Choose TZ iBoat on Android?
TZ iBoat is a strong Android marine navigation app for boaters who want a complete set of tools in one place.
Coastal cruisers: charts, routes, tides, weather, AIS, offline access, and mooring tools for everyday navigation.
Sport fishing users: oceanographic data, currents, bathymetry, and offshore planning tools.
Android tablet users: a larger-screen navigation setup for planning and underway use.
Why TZ iBoat Now Belongs in Best Boating App Lists
TZ iBoat has historically been underrepresented in boating app rankings because Android users could not access it. With TZ iBoat 4 now available on Android, that reason no longer applies.
When evaluating the best marine navigation apps, TZ iBoat should now be included because it offers both iOS and Android phone and tablet compatibility with everything a modern boater needs for their time on the water.

Cloud technology is exciting and the possibilities surrounding the technology are expanding each day. Will cloud finally reach the sea? Cloud coverage for the marine navigation industry is almost inevitable. It really is just a case of when, not if. TIMEZERO is currently developing a tool that will circumvent pricey satellite internet provider fees.
Cloud technology would still open up a list of possibilities to marine navigation software. Let’s take a look at some of these!
Our redesigned user interface will make your life much easier when it comes to route planning and all the features you are familiar with (Tides, Currents, Weather Forecast, etc.). All the concepts which made TIMEZERO a huge success (Tool Bar, Layers and Navdata) are now included in an enhanced User Interface fully adapted to be used on touch screens!
Security Cone
The new Security Cone is a feature in adherence with the official rules of the IMO. It uses the data in vector charts or the 3D data within the charts to detect shallow areas and isolated dangers. If an obstacle is detected inside this cone in front of the boat’s trajectory, an anti-grounding alarm will automatically be triggered.
Secure Route Planning
Route Planning is of the utmost importance for every boater. Our new technology assures the security of a route upon creation. Through color codes (green/red) it is instantaneously possible to know if the depth is sufficient for the safe passing of your boat.
And more!
Note: The release of TZ Navigator will mean that we will stop supporting all TIMEZERO v1.9.8 and below. We will continue however to support v2 on all compatible operating systems until the end of 2016 (Windows XP, Windows 7 and Windows 8.1).
We are very pleased to announce the official launch of TZ Professional v3, the biggest TIMEZERO release ever!
Since its release back in 2007, our range of TIMEZERO products has not stopped evolving, always maintaining the same objective: to provide a product that meets the most demanding needs of professionals at sea. Close to 25,000 vessels currently use our TIMEZERO software. This new version offers an incredible amount of new features specifically designed for both professional fishermen and workboats.
