Description
🔌Your connected car 🚘
Is your Check Engine light on? inCarDoc turns your phone into a professional OBD2 scanner — read fault codes, monitor real-time engine data, track fuel economy and keep your car's full history in one place. Works with ELM327 OBD2 scanners via Bluetooth or WiFi.
Requires ELM327 or compatible OBD2 adapter. Demo modes available without adapter.
🛠 Car diagnostics
Read and clear Check Engine codes (DTC) instantly. inCarDoc shows you the fault code, its full description, and related freeze frame data — everything you need to understand what's wrong and decide if it's serious. Save and share diagnostic reports when visiting a repair shop.
Supports Engine and Emission systems as defined by the OBD2 standard.
⏲ Real-time parameters
Monitor live engine data straight from your car's sensors: speed, RPM, coolant temperature, pressure, O2 oxygen sensors and many more PIDs. View data as charts or analog/digital widgets. The exact list of available parameters depends on your car's make, model and year.
⛽ Fuel economy 'Economizer'
Economizer tracks your gas consumption in real time — instant and average MPG, per-trip and per-day statistics. For accurate results, enter your engine displacement and volumetric efficiency (default: 80%). Requires MAF or MAP+IAT+RPM parameters to be supported by your car.
♾ More features
• Logbook: fuel records, service history, maintenance notes • Console mode: direct OBD2 and ELM327 commands for advanced users • Custom configurations for non-standard parameters and protocol • Upload and sync data to web
Unlock advanced features, extended PID support and an ad-free experience with inCarDoc Pro.
🔐 Why we need permissions
Every permission inCarDoc requests is essential for the app to work properly:
• Device & app history. Keeps the app running reliably in the background; • Location. Enables GPS speed, altitude, and location-based service search; • Photos / Media / Files. Saves your Logbook entries and diagnostic data locally; • Bluetooth & WiFi. Connects to your OBD2 scanner and syncs Logbook to the web.
⚠️ Important: adapter compatibility
Some cheap ELM327 clones (often labeled v2.1) may cause connection issues. If you experience problems, please contact us by email with your adapter name, MAC address, ELM327 firmware version and a connection log — this helps us build a public list of problematic adapters and protect other users.
To help improve OBD2 coverage for your car, go to the configuration screen, fill in your car details and tap Send in the 'General information' section.
For questions and support, please contact us by email support@incardoc.com — we have limited ability to respond to Play Store comments.

I love it completely 😊

I own couple of cars, this app works like magic with cheap obd2 scanners, also with multiple adapters, you just simply need to connect the app with the obd2 scanner you are currently using, and it works like charm. I have obd2 adapter connect in every car at all times for live data monitoring and the app works great with every adapter and every vehicle. YOU JUST MUST BE PATIENT AND SET UP THE APP PROPERLY. Then it works flawlessly

I have always promoted this app until now. Requiring your location is an absolute unnecessary permission for an OBD2 reader. I can accept needing nearby devices, but when I deny access to my location it will not connect the Bluetooth device. Clear storage and do the exact same setup with location allowed and it works. I have used this for years and hope the developers can resolve this requirement. Oddly enough, when I tried some other readers, they did not require location permissions.

All other obd2 apps worked but this one doesn't. Uninstalled. It's a waste of time on Wi-Fi. Response-the other apps worked just fine. I wasn't needing help getting it to connect. It just wouldn't
