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.

Pretty Awemos!(More awesome than Awesome) Car Scanner works well, has many PIDs, and ones that it doesn't have can be manually added! Includes the ability to set the priority of each individual sensor for refresh rate control (under sensor properties). Plus it's a FREE app! I paid anyway not because the ads were intrusive , but just because it was better than others I've tried. It's Better Than TORQUE! I've had "mixed" results with the acceleration tests(1/4mile etc) but that is to be expected.

Paid version, better than expected. Not recommended to leave odb connected while driving for extended periods. Nothing to do with the app. An odb reader can cause a vehicle to have strange malfunctions if left plugged in. Mine almost always causes my cruise control to send the car into limp mode. But like I said, not the apps fault. It does it with every scanner app I've tried. The app itself is the best I've used. My hats off to the creator.

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.
