Best dyno app
Very accurate dyno and
timed run

Matt Blake
Excellent
The results are spot on, very impressive for "only" an app compared to a rolling road.

How It Works ?
It's simple

1. Create your car profile
Describe your car to PerfExpert by providing information such as car weight, tire sizes or engine displacement (see complete parameters list in the FAQ).
2. Mount your phone firmly
No need to connect your phone or tablet to your car. With your device firmly mounted inside your car, PerfExpert can rely on your device's sensors to measure real car acceleration.
3. Accelerate through the entire rev range
Find a flat, straight, level road with no traffic and perform an acceleration from low rev to max engine rev, holding the same gear : that's it!
Features
The base app is a one-time purchase available on the App Store and Google Play
The Pro subscription is an optional in-app upgrade that unlocks support for the following external GPS devices : RaceBox Mini | Mini S | Micro, VBox Sport, Racebox.ru
