Customer Reviews

Used for over 2 years

I first got InavX when I installed a wi-fi enabled AIS to supplement my on-board navigation instruments. I really like the route making capability and the fact that I can import/export routs between my IPhone and IPad. I also like the ability to track AIS targets with it.

I downloaded Gribs while offshore with my Globalstar phone on two crossings of th northern Gulf using XGate and a Redport optimizer. I am currently assisting a friend who is in SW Florida teaching an ASA class with weather forecasting using the weather functions. Impressive app. Now if only I could get my on-board radar on it too!

This is a five star app!

Will not use anything else

I've been using this nav app for several years. I have tried others, but they always leave out something to force you to use their plotter. With this program, I "technically" don't need anything else.

The BEST boating and Marine Navigation App

Without a doubt this is the best marine navigation app. I've tried them all now and iNavX is the only app I used.

Whether I'm sailing in San Francisco or open ocean racing, iNavX's comprehensive features and access to all the charts I need, clearly sets it apart.

Don't be nickel-and-dimed by cheaper apps with all their IAPs. I ended up spending a lot more than what iNavX charges and got a fraction of the features.

More importantly, through iNavX's partnership with X-Traverse I got all the international charts I need. Really helpful when I was sailing the Virgin Islands this spring.
