“Best Navigation App Interface” by Whitall

Like probably most sailors and boaters, I've tried a number of navigation apps. Navionics, iNavx, Plan2Nav, even Garmin. I find this one far more intuitive, and beyond easy to use - a joy to use.”

TZ App is the application that provides real time marine chart navigation free of charge. Developed using TIMEZERO technology, TZ App has been specially created for recreational sailors and sports fishing alike. With more than 95,000 users who put their trust in TIMEZERO for their trips out to sea, it is truly an internationally adored software program!

TIMEZERO technology offers a 2D/3D chart engine. Merging charts with satellite land images using PhotoFusion and the most precise marine charts thanks to the exclusive Raster format mm3d by MapMedia as well as Vector charts by C-Map. The 3D chart engine allows you to navigate your charts by zooming and investigating from 2D to 3D without any loading time. It is an App that works in real time and is ideal for accomplished sailors and sports fishermen!

Best charts on the internet

Xavier Itzmann

We use this app because of its top-notch raster charts, all from strictly official sources. For example, In France, the charts are from SHOM, in the UK, from UKHO, in Turkey from SHOD, etc. It is just like using paper charts straight from each country’s government... at very reasonable prices.

Weaknesses... the AIS module show _all_ available data about the other boats... except their names! How crazy is that? And the boat instrument data includes all important sensors, including depth... but wind is not included! Talk about an oversight! It is for these little details that this app does not get 5 stars. Will give 5 stars once these weaknesses get fixed.

Best plotting and navigation app out there


I have a Garmin 7616 MFD and the Garmin Blue Chart App but I use the MaxSea App on a IPad Pro 12" for all my plotting and navigating (with the exception of future day tides and currents for which I use Blue Chart). It takes about 20 seconds to plot a run from Newport to Annapolis.

Super Nav. App especially with Explorer Charts for Bahamas.


The is the best overall Chart app even if it still only uses Raster charts. They take a bit of time to download but its worth it.
i have tried them all. Best app for IPad and easy to use.
