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.

OK, there are some nice features to this app, it's a good app. My complaint is in the logging, it is INFURIATING. First you have to export one by one. The two CSV options BOTH have terrible structuring. Let alone the misspelling of Longitude that trips most data analysis tools. And lastly, when exporting you can save to file or email, but if you save to file you cannot actually save TO THE DEVICE! Gaaa

Holy cow, this app is fantastic! It worked right away with my Veepeak OBD2 adapter, it came with dozens of screens that showed tons of data for my EV (not gas car stuff), and it worked on the 10-year-old phone that I dug out of a box. I did all this with Torque over a decade ago and that was like pulling teeth; this time, it was working instantly! I'm truly stunned. My only complaint is that I can't figure out how to pay for it twice :) I put it on two phones (one dedicated to car OBD2).

It used to work great with my Bluetooth obd2 reader, and now it's just won't connect. Other apps connecting to the unit with no issues so there must be something in the app. I tried to restart, reconnect the Bluetooth unit, checked for updates.. nothing worked. It's a bit annoying since I paid for the full version. Any recommendations?
