FourStroke is a powerful tool that analyzes and displays real-time vehicle sensors and data through your vehicle's OBD-II port, a port standard on most vehicles across the world. Use of this app requires a compatible OBD-II Wifi Adapter. Our app is FREE to pull and clear engine codes along with most other functionality! We do have extended functionality as part of our in-app purchase for those looking for additional tools. FourStroke will work with any non-proprietary OBD Wireless adapter.

FourStroke can convert your iPhone into a heads-up display of just about every sensor your car supports, without needing expensive gauges. Sensors include RPM, coolant temperature, vehicle speed, air flow, O2 sensor data, and more (sensor support may vary based on vehicle OBD system).

Quickly diagnose a check engine light (CEL) by pulling up exactly what error codes are present. FourStroke automatically turns the code into a readable description. Your vehicle also may store 'Freeze Frames' that detail what sensor data was present when the CEL first occurred; FourStroke can display this information for you.

DISCLAIMER: This app requires a third party OBD2 adapter. Please visit our website for details.
