About this app

See what your car is doing in realtime, get OBD fault codes, car performance, sensor data and more!
Car Scanner is a vehicle / car performance / trip computer / diagnostics tool and scanner that uses an OBD II Wi-Fi or Bluetooth adapter to connect to your OBD2 engine management / ECU.
Car Scanner gives you a bunch of unique features:

2) Add custom (extended PIDs) and get information, that was hidden from you by car manufacturer!
3) It can also show and reset a DTC fault code like a scantool. Car Scanner includes a huge database of DTC codes descriptions.

5) Now with Mode 06 - you can get ECU self-monitoring test results. Helps you fix your car and helps keep repair costs down!
6) Check if your car is ready for emission tests.
7) Check all of the sensors at one screen
8) Car Scanner works with any vehicle that uses the OBD 2 standard (most vehicles built after 2000, but can work for vehicles as far back as 1996, check carscanner.info for more details).

14) And one more thing - Car Scanner provides the widest variety of features for FREE across the Play Market.

The app requires a Wi-Fi or Bluetooth or Bluetooth 4.0 (Bluetooth LE) OBD2 ELM327 compatible adapter (device) to work. ELM327 devices plugs into the diagnostics socket in the car and gives your phone access to car diagnostics.
Recommended adapters brands: OBDLink, Kiwi 3, V-Gate, Carista, LELink, Veepeak.
If you buy one of the cheap china OBD2 ELM327 adapters from ebay / amazon, then make sure it’s not marked as v.2.1. This adapters are supported, but they have lot’s of bugs.

PLEASE NOTE: Vehicle ECUs vary in the amount of sensors supported. This app can’t show you something, that is not provided by your car.

Attention "bad" adapters! We faced the problem, that some adapters (often cheep Chinese clones), can’t connect to the smartphone or the car. Some of them can even make your car engine work unstable, often lost connection, increase time lag when reading data.
So, we recommend you to use genuine ELM327 or recommended adapter brands.

I wanted an OBD II phone app for my Honda Clarity PHEV, but didn't think I'd find one: this app is exactly right, works well and looks great on my Pixel 6, displays just what I need, is configurable, and has mirror mode to project right into my windshield. It connected to my BT OBD II adaptor in seconds with no fuss. After just twenty minutes of experience I did a forever purchase. I definitely recommend this app.

I haven't had this app very long yet, but it looks like a very good app. Seems to show every available sensor reading on the vehicle. I am looking forward to using it for a long time. Update: This app works great with all 3 of my vehicles, both EV & ice vehicles. I upgraded to the pro version ($5) so my profiles for each vehicle can have multiple screens to view on the dashboard. I have used it on everything from an old 1998 Chevy pickup to a 2023 EV. It works great on them all. Thanks 😊

I wish the ELM-327 & ECU connections were consistently stable....Car Scanner would be a good app. Bought the $5 paid version, and needed to reboot Android for a stable connect. More recently, it won't connect at all. I have used Torque for many years, with no problems connecting. I gave up on Car Scanner and tried the $5 paid version of OBD Fusion...no problems with connection. I'm impressed with both Scanner and Fusion's capabilities compared to Torque. Unfortunately, gave up on Scanner.
