Simple & easy

This is a great little app. I wish it had more options such as resetting the tps and some ui options , but it is very effective and the gateway is aces A++++

Great Product

I recently installed a Fox Marine Gateway on my 2004 Ebbtide and I'm amazed at how well it works. Installation was simple plug and play.

The APP provides a lot of detailed information from the ECM.

My only suggestion to the developer would be to offer an APP that translates the input data into usable gauge format. Which would allow users without a chartplotter to use the built in Bluetooth to display the engine gauges on a iPad or tablet thus making the Gateway nearly a "stand alone" system. I know boaters would be more than happy to purchase such useful APP.
