DISCOVER THE ONLY BOAT APP YOU NEED AT SEA!
TZ iBoat is the most advanced boat navigation app on the market, it gathers all the features necessary for safe maritime navigation:
Experience the revolutionary TZ MAPS: a cutting-edge marine chart format that integrates Raster and Vector data, detailed land information, high-resolution satellite photos, and high-resolution Bathymetry. Unlock the full potential of TZ MAPS with a 7-day free trial.
- AIS ONLINE: access AIS targets beyond your local receiver’s range by connecting to our global AIS network via the Internet. When enabled, any AIS targets within your local receiver’s range will automatically be shared with the community. Note: This feature requires the AIS module, which must be purchased to enable AIS Online.
- COMMUNITY MAPS: contribute to the marine chart data in your navigation area by commenting, note-taking, voting, and modifying or deleting objects such as buoys, obstructions, and points of interest (restaurants and supply stores) in a participative way that benefits the whole TIMEZERO community, developing the most reliable and precise boat map.
- DYNAMIC MOORINGS: discover classified nearby anchorages based on weather forecasts and topography. Dynamic color coding (Red, Orange, Green) provides wind direction for optimized anchorage comfort.
- DYNAMIC LIGHTS: visualize light sectors according to your boat’s position and field of vision. Navigation lights on the map can flash in accordance with your position. Highlighted and flashing lights represent only those within your actual field of vision.
- SMART SEARCH: access a high-performance search engine to find any information on our marine charts (tide stations, rocks, buoys, etc.) as well as in your user object database (marks, routes. etc.). No more wasted time searching your map for a marina; enter the name and it will be automatically located on the map.
- SMART ZONE: Set up an alarm for when your boat enters or leaves specific areas on the nautical chart (e.g., restricted areas). Configure the types of affected to suit your preferences. Display NavData to see a list of all zones in which your boat is located.
ATTENTION FISHERMEN! The following features have been developed especially for you:
- BATHYVISION: Discover the best bottom data available and display it dynamically and intuitively in color and/or with contour lines. Adjust the contour lines’ density and shading to focus precisely on high-potential fishing areas.
