Plug an ELM327 adapter into your car's diagnostic port, connect over Wi-Fi or Bluetooth, and see exactly what your engine is doing — in real time, in your language. No account, no sign-up, and your vehicle data never leaves your device.

🔌 CONNECT YOUR WAY
• Works with common Wi-Fi and Bluetooth ELM327 adapters.
• Auto-finds your Wi-Fi adapter on the network, or set the host and port yourself.
• No adapter handy? Demo mode simulates a car so you can explore every screen.

📊 LIVE ENGINE DATA
• Watch a customizable dashboard of gauges: engine speed, vehicle speed, coolant, throttle, load, oil temp and more.
• Add, remove and reorder gauges by dragging — build the layout you want.
• Smooth animated needles, or snap-instant mode to save battery on slower phones.

🛠️ FAULT CODES
• Read stored, pending and permanent diagnostic trouble codes.
• Fault-code descriptions are localized in 7 languages — read what a code means in your own language.
• Check the freeze-frame snapshot captured when a fault triggered.
• Review readiness monitors and clear codes to turn off the check-engine lamp (Pro).

🚗 YOUR GARAGE
• Every car you connect to is saved automatically — VIN, protocol, control module, sensors and fault history.
• Add a photo and edit make, model and year for each vehicle.
• Export a full vehicle sheet to PDF or CSV and share it with your mechanic.

🎬 RECORD & GRAPH (PRO)
• Record a live session and plot any sensor over time.
• Automatically capture a snapshot around faults that appear while recording.
• Export recordings for later analysis.

🔒 YOUR DATA STAYS YOURS
Everything your car reports is processed on your device and shown only to you — it is not sent to us or anyone else, and it isn't kept after you disconnect. CoreOBD only reads standard OBD2 data; it never modifies or reprograms your vehicle. The app needs internet permission to talk to Wi-Fi adapters and to show ads in the free version; it does not request location or track you.

✨ FREE & PRO
Free includes live data with the core sensors, full fault-code reading, your saved garage, and PDF/CSV export. CoreOBD Pro is a one-time purchase — yours forever — that unlocks every sensor on the dashboard, clearing fault codes, session recording with graphs and data export, and removes all ads.

Note: an external OBD-II ELM327 adapter (Wi-Fi or Bluetooth) is required — it is not included.
