About this app

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.

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.

Used this app out of the other ones because most of the features from other apps are behind a pay wall. Everything that you need in this app is free. I decided to purchase the paid version because it was cheap and even though I didn't need the extra features the paid version has, I wanted to help support the developer and consider that an investment into the app.

best value for money among the top 5 listed here, $5 Lifetime, the only one that works without having to pay. I bought it to support it because the app solved it on the first use, for free, without crashing, fast and efficient, it worked beautifully with my Tackylife OBD II reader. you should make a partnership because the apps they indicate are pretty bad. Congratulations on the business model and the app. I became a fan, looking forward to the upgrades. success.

can't find my old app that I used with my VEEPEAK Bluetooth obd2 reader, so got this. And I am definitely pleasantly surprised so far for the 2 hours I've been using it. That being said compared to the app I used to use, the user interface is definitely more clunky and requires a little bit more knowledge of vehicles in general and it's Definitely not as pretty looking. I will mess around with the custom settings though for the live data screens. probably going to upgrade to five stars soon.
