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 4.0 (Bluetooth LE) adapter to connect to your OBD2 engine management / ECU.
Car Scanner gives you a bunch of unique features:
1) Layout your own dashboard with the gauges and charts you want!
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.
4) Car Scanner allows you to read free-frames (sensors state when DTC is saved).
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 for more details).
9) Car Scanner includes a lot of connection profiles, that gives you some extra features for Toyota, Mitsubishi, GM, Opel, Vauxhal, Chevrolet, Nissan, Infinity, Renault, Hyundai, Kia, Mazda Skyactiv, and others.
10) Car Scanner dashboard includes a HUD mode, that you can use to project data to your windshield.
11) Car Scanner provides a tool for very accurate acceleration measurments (0-60, 0-100, etc.)
12) Car Scanner can be used as a trip computer and can show you fuel consumption statistics!
13) And one more thing - Car Scanner provides the widest variety of features for FREE across the App Store.

The app requires a Wi-Fi or or Bluetooth 4.0 (Bluetooth LE) OBD2 ELM327 compatible adapter to work. The adapter is small and plugs into the diagnostics socket on the car which gives your phone access.
Recommended adapters brands: Kiwi 3, Viecar, 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 tried atleast 10 apps, for a Generic ELM 327-wifi dongle, which was the cheapest I could find. This App, had the options that most apps had (standard) and then quite a few more. Apps ranged in ease, of Setup. But this app, was Simple, and was able to fund my cheap reader on it’s own. Without doing anything besides selecting it on my iPhones wifi. Which was something you do with all apps, until phone auto connects after first setup. Love the amount of stuff you can change with custom dashboard gauges. More then most the apps. Buy it. And I recommend buying an OBD reference app, that is make specific to your vehicle to go with whichever app you choose. Even store bought expensive scanners, are vague as hell when you look up the erroe codes. Fixed my car, and saved alot of mechanic guessing.

Ease of use

I bought the cheap ELM327 adapter with no expectations. It is an affordable option before going to a mechanic. The Car Scanner app is easy to use and navigate. Just upgraded to the Pro paid version. With this app and adapter combo it’s already saved me some time and money.....Thanks Developer

The free app was just what I needed to do my repairs but you don’t find this type of quality even in some purchased apps. Just want to thank you for your hard work. I strongly recommend your app to my friends.
