What is PerfExpert?

PerfExpert – Car Onboard Dyno & Timer is a professional-grade app that lets you measure your car’s real performance:
• Engine power & torque curves
• 0–60 mph / 0–100 km/h acceleration times
• Quarter mile / 400 m times, and more.

All tests are performed using just your phone — no connection to your car required. Results come in detailed reports with interactive charts.

How does the dyno work?

1. Create your car profile
Enter key specs like curb weight, tire size, and displacement. If you’re unsure, the app helps you find them.
2. Mount your phone securely
No need for OBD or external sensors. PerfExpert uses your phone’s internal sensors to capture acceleration accurately.
3. Perform a full-throttle pull
On a flat, straight road, accelerate from low revs to redline in one gear — done!

Note: Dyno tests are not compatible with automatic gearboxes that lack a manual mode.
