The app is on the Play store for android use. search "Mpguino Blue"
I need some support to get into the apple process, it requires an outlay to get a developer license and I have no way of testing it myself on an apple device. The program is written using a cross platform design so it in theory should work out the box, but things like screen rotation problems and bluetooth comms may need testing.
recently it was installed on an outboard fuel injected boat, with great results for just measuring fuel flow for trimming the motors in a cruise.
The dynamic graph is mesmerizing when driving :P very useful, and changing settings over bluetooth is far easier than using the touch screen.
Pictures of the app are on the mpguino page of my website.
