The app requires a Wi-Fi or or Bluetooth 4.0 (Bluetooth LE) OBD2 ELM327 compatible adapter (device) to work. ELM327 devices plugs into the diagnostics socket in the car ang gives your phone access to car diagnostics.
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.

### 5/5 — Business owner

*2026-08-20, version 2.1.46*

Tried out free version, it has everything we needed to do just about every job, it has out done a $16200 scanner in almost every job. Very good on iPhone for portability while test driving with out the bulky tools and cables, very big well done for the app and highly recommend

### 5/5 — Great free app

*2026-08-17, version 2.1.46*

Best app, have a mk4.5 focus ST, tried the forscan one that costs around £8 and this one is better for what I wanted (battery Soc monitoring and fault codes).  The good thing with this one is you can display it via apple carplay, so all the reading are in the dash, which is great as others you need to look at the phone to see the info.  Paid the £7.99 to get the full version as feel it’s worth the money.

### 1/5 — Used to be good

Can’t think of a better one!

### 5/5 — What it says on the tin

*2026-08-04, version 2.1.46*

I had an engine management light come on in my Ford Mondeo. I contacted fords who wanted £180 just to scan the car for fault codes. So I’d thought I’d look around and found car scanner. Within 10 minutes I found what the problem was. So a cost price of £7.99 for life or a £180 costs at Fords. No brained
