Nobeltec TZ iBoat 4 arrives on Android with rebuilt navigation tools

When the primary plotter is buried under spray and the backup device has to take over fast, a clunky mobile nav app becomes a real problem. Nobeltec said June 2 in Beaverton, Oregon, that TZ iBoat 4 is now available on Android for the first time, and the release is not a simple port from iOS. The company rebuilt the app with a new design, a reimagined user experience and dedicated screens meant to make cockpit use less fumbly on mixed-device setups.

For day-to-day sailing, the most useful changes sit in the layout. The Apple App Store listing says TZ iBoat 4 adds a TZ Bar for quick access, plus dedicated screens for Weather, Fishing/SportFishing, NavData/Instruments, Logbook, Mooring/Anchor, Tides and Sounder. It also promises a cleaner chart view and customizable interface options. Nobeltec and Furuno both point to upgraded weather tools as a major part of the refresh, including real-time and offline weather access, rain radar with lightning data, and higher-resolution weather models in the Premium tier.

The app also leans harder into the kind of extras that matter when a phone or tablet is doubling as a backup nav station. The listing says TZ iBoat 4 includes improved NMEA connectivity, better latitude and longitude entry, stronger marina display on charts, AIS Online, radar and onboard instrument integration, community maps, dynamic lights, dynamic moorings, BathyVision bathymetry and support for Iridium GO!. Elite subscribers also get ocean layers such as sea surface temperature, chlorophyll, sea surface height and currents. For sailors running a budget electronics stack, those are the sort of tools that can fill gaps between an older MFD and a modern weather or planning workflow.

Nobeltec president Iker Pryszo called the release a major milestone for Android users and for the TimeZero ecosystem. The company said TZ iBoat 4 was completely rebuilt with a new architecture and redesigned graphics engine, with teams in Portland, Bidart and Barcelona involved in the work. Furuno said the app can connect with Furuno NavNet TZtouch multifunction displays and TIMEZERO PC software through TZ Cloud, sharing routes, waypoints and synchronized charts. That cross-platform handoff is the key reason Android availability matters now: it gives mixed-device cockpits a cleaner way to keep the same route, the same data and the same backup plan in play.

Panbo had been tracking Android interest for a year, noting in June 2025 that beta testers were being sought and that the beta would run until spring 2026. The App Store listing now shows 824 ratings and a 4.7 average, with trust from more than 500,000 boaters worldwide. For crews trying to avoid expensive hardware swaps, TZ iBoat 4 looks like a serious Android entry point rather than a cosmetic refresh, and that is the part that will matter most when the cockpit gets busy.
