Here are some screen shots of my Dash Command App.
These gauges can be configured any way you want. you can even have 2 gauges in one. the dial can read one parameter and the digital in the middle can read another. for instance the gauges in the 2nd pic I have RPM on the dial and coolant temp in the digital.
You can even do 0-60 and 1/4 mile times along with G forces if your into that kind of thing!
And for people that like off roading.....
These are even better with an I pad or a tablet. but the I phone or smart phone works great!
