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.

Ratings and reviews

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!

Works great with the Veepeak BLE+ OBD dongle on my 2025 Forester. It even was able to pull and read some hybrid system data. Best of all, it works with Android Auto! You can select the dashboard to display. It is text only at the moment (title and value, no graphical gauges) but it works and does the job! That was enough for me to pay and support the dev. I do wish you could add more color zones to the gauges (currently limited to two color lines) but otherwise very customizable.

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.
