I use my smart phone often as a tool for tuning my boat so I figured I would share a couple of my secrets and see if anyone else uses any other useful jet boat tuning apps.
I use the app “bubble” on my Droid X as a level and angle finder. It is handy for finding ride plate, nozzle angle etc in degrees to the nearest hundredth. It’s a valuable tool for recording where you have your equipment setup while testing.
I also use the UlysseSpeed GPS speedometer which includes features for top speed, distance, etc. This saved me the $ of having to buy a handheld GPS to see if my hardware changes are helping or not.
Also, don’t forget the flashlight app. It’s absolutely a must have.
