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.

What's New

Updated connection profiles database.
Bugs fixed.

I'm a Single lady and independent person, but not very car savvy. I can do minor stuff, but I leave the big stuff to the professionals. this app is AMAZING! I have diagnosed a few things and told my mechanic exactly what was wrong. it was correct. This app is so easy to use! And free! I was intimidated at first, being almost completely clueless, but directions were clear and I get all the info I need. my fav part is where it links you to articles and videos relating to the repairs needed!

good app. it has the most free features I've found so far of all the obd2 apps in the app store. and most importantly ... not a single ad. some of these apps are unusable due to the amount of ads. Also this is the only app I was actually able to connect to my adapter. I am going to buy the pro version for only $5 for a lifetime account! other apps wanted as much as $15 per month for the pro version. I'm still learning all the many options. thanks whoever made this app.

Just got free Car Scanner app. Started checking it with various devices. I want to be able to graph my fuel trims while vehicle running. Free version allows you to graph 2 parameters at a time. The graph is good. When I found out the upgraded paid version was only $5.+ for forever use, I bought it without even check more devices in more cars with the app. Anyone who puts this much in an app and only charges $5 to use it forever deserves $5 just on general principles!!

After Torque Lite stopped getting updated, I needed something else that worked just as well. I came across this app after trying 3 others. For someone who has to work on their own vehicles, this is perfection. We're a large family who believes in living within their means and that equates to buying older vehicles we can afford outright and doing most of the repairs ourselves. The features I need are in the free version with the more professional ones being what you pay for. Thank you.

I heard about this app being good for use with EVs. while it won't replace a $500 scan tool,it gets for 90% there at a fraction of the cost. I really enjoy how every time I connect to the car, it logs the information that I can pull up at a later date and search for specific items and see how things have changed over time such as the state of health of my battery or seeing how different charging speeds effect battery temps.

Fairly comprehensive The only thing I wish it could do is program keys and remotes, if it is there I haven't found it yet. Only used it once to realize it was good. Previously I had used another app, but had limited info. I thought my Bluetooth reader didn't read right. I was looking at another reader ($400+) but decided to look into this app first. Sooo glad I did, almost every option was suddenly there and functional.
