"I just wanted to thank you and let you know that iNavX on my iPad really worked well for us on the Oregon Offshore last weekend. I had the iPad in a dry case and we used the basic functions of the iNavX program to navigate our way to an overall victory. I shared the program with a number of competitors after the race and I'm pretty sure they'll be visiting the app store soon."


"I successfully used iNavX to input 1,695 waypoints stretching from the waters of Northern Mexico to the Channel Islands. I was then able to export those points and send the exported files to my Furuno dealer who used a Furuno program to convert the file to Excel and sent it back to me. Thank you so much for providing the platform for me to get this project done. I could not have done it without you."


"I've used this app while cruising on a 36 ft sailboat all along East Coast for 6 years. It is not my primary Chart plotter but an excellent back up and even better for planning routes and exploring options for anchorages. All NOAA raster charts are free. To put this in perspective my primary Chart Plotter from Garmin costs $900 and requires $250 per Chip just for the Chesapeake Bay region."
