Customer Reviews

Outstanding Nav App - Professional Grade

Just navigated/travelled 460 NM in the San Juan Islands and Canadian Gulf Islands using iNavX and for the second year can report flawless operation and ease of use. Yes, I have a Navman and a Garmin chartplotter but they don't come close to user friendliness and convenience while in port planning or while underway. There are those that just want to passively watch their boat move over a chart, but my boat cruises at 20 Knots and I need to pre-plan and pre-clear my waypoints and assemble them into a route to follow for safe and flawless passage through passes and channels that are known to challenge and sometimes frustrate the boaters using them. Kudos to the developers for a fine and professional product. I have only one question: why does our legal system force all navigation software developers to state that their products are for reference only and not for navigation; only approved NOAA charts are to be used for navigation. Even the USCG and USN use apps (ECDIS) and digital charts for navigation while carrying paper charts for safety back-up purposes.

Putting chart plotters out of business

An outstanding navigation app! Having used virtually every chart plotter and software available to me in the past 15 years, iNavX takes the cake! From day sailing to long passages, I've relied on the software for the past 4 years and am always amazed. I very comfortably navigated from Block Island to the Exhumes and every spot in between with stunning accuracy and ease. All this from the convenience of an iPad. Along with the great software come outstanding customer support. Always able to talk with a person on the phone and solve issues within a matter of minutes. I don't plan on buying another charting system for as long as iNavX is around!


I have used INavX for a couple of years in combination with bad elf GPS. I have great confidence in the program and keep in front of me at the wheel and in my berth when I'm off watch to keep an eye on things. Now that quilted charts are available on my IPad, I don't need to check my main nav program at the nav station as often.
INavX makes giving quick course and distance info to crew very easy, most wonder how I know the info at any given moment, they think I'm a genius.
There is a great deal yet to learn in this program, I learn more on every passage.
Last but by no means least is the quick email response to every question I've had with iNavX.
