OBD2 Car Scanner Pro ELM327

Turn a compatible OBD-II adapter into a clear, modern diagnostic dashboard.

It connects to Wi-Fi and Bluetooth LE ELM327-compatible adapters, detects what your vehicle actually supports, and shows the data it returns. No account, and the diagnostics work offline.

LIVE DATA
• RPM, speed, coolant temperature, engine load, throttle position and module voltage
• Over 20 more when your ECU exposes them: MAF, manifold and barometric pressure, timing advance, fuel trims, fuel level, intake and ambient temperature, runtime and distance
• Cards or analog-inspired gauges, with monospaced digits that hold still
• Parameters your vehicle does not support are labelled, not faked

READ AND UNDERSTAND CODES
• Read stored and pending diagnostic trouble codes
• Generic OBD-II code descriptions are carried in the app, with family and system group
• Manufacturer-specific codes are marked as such, not given a guessed description
• Clear supported emissions codes, with an explicit warning about what that does

AI ANALYSIS (PRO)
• Runs on the session you just read: codes, readiness, freeze frame, live values
• Possible causes with reasoning and stated confidence, cheapest and safest checks first
• Shows the exact values before anything is sent, and never sends your VIN or location
• Optional — the on-device insights always work without it, offline and free

DIAGNOSTIC DETAIL
• Freeze frame: the conditions the ECU stored when a code was set
• Emissions readiness: which monitors have completed their drive cycle
• VIN reading where your vehicle supports Mode 09
• Battery and charging: voltage, a trend, and 30 days of daily min/avg/max

GARAGE
• Save vehicles with make, model, year, fuel type, mileage and VIN
• Track oil, filters, brakes, tires, spark plugs, battery and coolant
• Optional service reminders, scheduled on your device

RECORD AND EXPORT
• Record a live session: min, average and max for every parameter
• Export sessions as CSV
• Generate a Vehicle Health Report as a PDF and share it

PERFORMANCE TESTS
• 0–60 mph, 0–100 km/h, 0–200 km/h, 1/8 mile, 1/4 mile and 100–0 braking
• Measured from GPS ground speed, with each run's GPS accuracy shown
• Personal bests and history per test

BUILT TO BE HONEST
• No account, no ads, no cross-app tracking
• Your vehicles, codes, sessions and reports stay on your device
• Core diagnostics work with no internet connection

WHAT YOU NEED
A compatible Wi-Fi or Bluetooth LE ELM327-style OBD-II adapter, and a vehicle with an OBD-II port. Compatibility depends on the adapter, vehicle, ECU and the PIDs it supports. Classic Bluetooth (SPP-only) adapters and dongles needing their maker's own app are not supported.

FREE AND PRO
Free includes adapter connection, an essential live dashboard, code reading, a basic readiness overview, one saved vehicle, oil-service tracking, one recording and one PDF report.

Pro adds AI analysis, the full parameter dashboard, gauges, live charts and themes, unlimited recordings with CSV export, code c
