Description

Turn your phone into an OBD2 car scanner. Plug in an ELM327 adapter over Bluetooth or Wi-Fi, read fault codes, clear the check engine light, and watch live engine data in real time. No account, no subscription, no server — everything runs on your phone.

CHECK ENGINE LIGHT & FAULT CODES
Read stored, pending and permanent trouble codes (DTC), see what each one means in plain language, and clear the check engine light in one tap. 879 generic SAE J2012 code meanings are built into the app and work with no internet.

CHECK BEFORE THE EMISSION TEST
Before you pay for an emission or PUC test, the app checks what most often causes a failure: the check engine light, emission-related fault codes, and a fuel mixture running too rich or too lean from fuel trim. You get a three-level verdict with the findings, so you can fix things first instead of paying twice. The app does not measure exhaust gas and does not declare a pass — that is for the official test equipment. Pro adds I/M Readiness and Mode 06: emission monitor status and the on-board test results behind them, namely catalyst, O2 sensors, EVAP and EGR.

LIVE DATA IN REAL TIME
RPM, speed, coolant temperature, throttle, engine load, battery voltage, MAF, O2 sensors, short and long term fuel trim, timing advance and more. Tap any parameter for its lowest, average and highest value, a mini chart and an explanation of the normal range. Parameters your car does not support are hidden automatically.

FUEL ECONOMY, BATTERY & PERFORMANCE
Trip computer with km/L or MPG, distance and estimated trip cost. Battery and alternator verdict from cranking and charging voltage. A 0–100 km/h test (automatically 0–60 mph on imperial units) with your own record list.

MAKE IT YOUR OWN
Build a custom dashboard from the parameters you care about. Add custom PIDs (mode, PID, formula). Set parameter alerts that vibrate and notify you when coolant temperature, voltage or RPM crosses your limit. HUD mode reflects the display onto the windshield for night driving.

FOR THE WORKSHOP
Freeze Frame captures engine conditions at the moment the fault was stored. Record sessions, keep them in History with charts, export CSV, and share a PDF diagnostic report with your mechanic over WhatsApp. Read the VIN straight from the ECU, plus Calibration ID, CVN, ECU module name and active protocol.

CAN'T CONNECT? START HERE
A built-in Connection Help guide walks you through Bluetooth and Wi-Fi adapter problems step by step. Protocol Scan and an OBD2 terminal are there for stubborn adapters. Demo Mode lets you explore every screen with no car and no adapter. Support email is free for everyone.

COMPATIBILITY
This car diagnostic tool works with ELM327 OBD2 adapters over Bluetooth or Wi-Fi, on OBD2/EOBD-compliant vehicles — generally fuel-injected cars from 2008 onward, some earlier. It covers standard OBD2 diagnostics, the part that is the same on every OBD2 car, rather than manufacturer-specific functions. Genuine adapters are strongly recommended; the cheapest v2.1 clones are unreliable with every app.

FREE
Live data, read and clear fault codes, fuel economy, immobilizer check, vehicle info, OBD2 terminal, connection help, demo mode.

PRO — ONE-TIME PURCHASE, NO SUBSCRIPTION
Custom dashboard, custom PIDs, parameter alerts, HUD, battery check, 0–100 test, Freeze Frame, I/M Readiness, Mode 06, VIN read, history and recording, PDF report, and no ads. Try every Pro feature free for 12 hours before you decide.

PRIVACY
Your vehicle data stays on your device. We run no server and ask for no account. Anonymous usage statistics can be switched off in Settings; trouble codes, VIN and location are never included.
IMPORTANT: For diagnostic use. Do not operate the app while driving. The performance test is for closed or private tracks only and is at the user's own risk.
