PerfExpert - Car Onboard Dyno & Timer allows you to measure the performances of your car, such as its real power, torque, and acceleration times. It doesnât require any connection to your car. Results are provided as detailed reports featuring interactive charts.How does PerfExpert dyno works ? Its simple :1. Create your car profile => Describe your car to PerfExpert by providing information such as curb weight, tire sizes or engine displacement. If you dont know how to find your cars specifications, we help you to do so.2. Mount your phone in your car => No need to connect your phone to your car. With your phone firmly mounted inside your car, PerfExpert can rely on its internal sensors to measure the real acceleration of your car.3. Accelerate through the entire engine rev range => On a flat, straight and horizontal road, perform an acceleration from low rev to the maximum rev, keeping the same gear : thats it!IMPORTANT : dyno test is not compatible with automatic gearboxes that doesnt have a manual mode.With such a tool, you can check the efficiency of your various tunings, ECU mapping, chiptuning, and even your chassis settings.Using the specification of the tested car and your deviceâs accelerometer, the application runs our algorithms and dynamic power loss calculations to provide the performances of your car with high accuracy.Skeptical?

Reviews
Even on an uneven road I got really close to what the specs should be, great app
Takes a while to fill everything out i can put car on a real dyno quicker. Much preffered older version. Im now going to uninstall app by everyone. Good luck.
This is the best app that I've found to measure the stats on your car and keep track of performance improvements.
FAIRLY ACCURATE providing you input the correct data prior to testing in vehicle.
Originally gave it one star because it didn't have my car, then the developer contacted me and had it put in, still missing several cars, including every Acura except mine, so it might not be worth it for someone with an Integra, but I don't tally know how it works, so...yeah, get this app.
Very good app indeed.
