Your Phone Is Now a
Pro Diagnostic Scanner.
Read and clear check engine codes, monitor live engine data, time your 0-60 and quarter mile, and track your vehicle's maintenance. Free with any Bluetooth OBD2 adapter.
Professional Diagnostics. Zero Cost.
Everything a dealership charges $100+ for — check engine codes, live data, performance testing, and more — free on your phone.
Check Engine Code Reader
Read and clear check engine (CEL) and powertrain trouble codes in seconds. Get AI-powered explanations for codes like P0420, P0300, P0171 — know exactly what's wrong and whether you can fix it yourself. It also reads ABS, SRS/airbag, and transmission codes.
Live Engine Data & Gauges
Monitor RPM, speed, boost PSI, coolant temperature, throttle position, engine load, MAF, O2 voltage, fuel pressure, timing advance, and battery voltage in real-time with beautiful gauges.
Drag Strip Timer & 0-60
Time your 0-60 mph and quarter mile using real OBD2 speed data — more accurate than GPS-only apps. Drag strip christmas tree staging with reaction time and trap speed. Record video with your speed and time shown on screen.
Ask AXLY — AI Diagnostics
Get a plain-English diagnosis for any trouble code, researched for your exact year, make, and model with live web search — the most likely causes, the first thing to check, and real sources to back it up. Your first few are free; grab a question pack whenever you need more.
