Comments and Reviews from users:

A Google user: “I tried a few other high ranked free apps. The others either didn't display what a code meant or didn't give you any codes at all. This one helped me figure out a misfire code and an idle air control issue. Fixed both myself for under $60. Debating getting the paid version because this app is awesome. Update: I bought the app. Love it. I use a $10 bluetooth OBDII I found on Amazon and have no issues. So if it can work with my cheap reader, it can work with anything.” – 5/5 in Play Store

A Google user: “app works good. i use it to turn off the engine light so i can use my remote start. evap emissions small leak is the code. I'm not ready to fix that one yet. But the app works fine. Not a ton of stupid ads either. Sometimes it doesn't want to connect via Bluetooth but that's not the apps fault... its my phone. Dont know how it could be improved so it gets 5 stars.” – 5/5 in Play Store

Does not access ALL OBD features for my car, but a full OBD scanner is literally thousands of dollars. If I may request a feature, please save current configuration. It's boring to enter all parameters each time the app start. At least Bluetooth port, car model and monitored variables!” – 5/5 in Play Store

A Google user: “The app works quite well for me. I especially like the reports feature with which I can save a fault code(s) readout to a web page file; very nice. Bug report: a mileage reading does not save to the diagnostic report file. I am not sure whether the app can pull the mileage reading from the ECU, however, the manual entry, just before the diag. report is generated, doesn't work.” – 4/5 in Play Store

A Google user: “One of the best apps on obd. Was disappointed on torque given the limited protocols it supports via elm327..... However, motordata live readout speed is toooooooo slow. Maybe you can provide a readout speed adjustment for phones & devices that can accept the speed. The graphs are also tooo tiny with too little readout points (i think because of the readout speed), and sweeps to the beginning after 1 frame... Otherwise great app. I don't even need the dials guu as seen in other apps. Just fix the two items and i will give you a 5 star Edit:Okay there is your five star. Not the answer i was looking for, but it works. The graph should read what i choose and ignore the rest so that i don't have to change the readout parameters every time. I hope the graph interface could be better/much bigger or something in the future. And i still feel like the readout speeds can be improved without limiting the items (given that other apps can do the same at much faster speeds). Thanks.” – 5/5 in Play Store

A Google user: “Great app! without plugins working good but with basic parameters readings- enugh to read and clear errors. With plugins (toyota) works good but reading of some parameters depends on your model ecu. Keep in mind this app, even with plugin, can not substitute profesional diagnostic. Also works limited with with some adapters (blue compact elm327 OBDII). In that case you'll get message as you try to connect. Support is responsive!” – 5/5 in Play Store

In the 'Test Results' part of the app, the menu button doesn't appear at the top of the screen, so I have no way to access the O2 data graph feature. I also have this app on an android tablet and it has the menu button at the top of the page. This is very annoying, because the O2 data graph is one of the best features.

A Google user: “It only scans Engine Control Module (ECM) and Transmission Control Module (TCM). It does not scan any other modules such as ABS, VSC, etc. So it's about the same as a cheap handheld scanner in that regard. The Pro version also has sensor monitors with data graphing and logging, which made it worth it for me to do a one month subscription. This part helped enabled me to figure out the problem with the car. But I had to use something else to read the ABS and VSC codes since OBD Auto Dr. doesn't read those... It paired fine with my Carista adapter, which is just a ELM v1.5 with v4 Bluetooth that works with Android, IOS, Windows.” – 3/5 in Play Store

lawrence p kortuem: “This app has poor readings on my Rogue and Frontier. No graphs,. won't read O2 sensors, data on main screen only has a few temp readings. When scrolling down, readings are blank Will pick up on the net but will not pick up Bluetooth.This app is not much better than a code reader. One good thing is that it has freeze frame data describing the condition and time the fault code was set. A positive is that it can be used with my PC and phone. App would be better if it had gauges. instead of the block design.” – 2/5 in Play Store

A Google user: “Ive been hacing trouble hooking up different sensors. The first time I used it on my grandmother's car, it worked. Now that I need to setup a new sensor for my car, it will not connect to my phone. Today I tried seeing why my tire light came on but it doesn't diagnose what the problem is. And 79.99 for an annual subscription, not worth it. When I first saw the ads, I was pretty excited to own one. After getting it and most of the options being inaccessible to non subscribers, not really happy.” – 3/5 in Play Store

Ivy: “This worked the first time I plugged it into my car. I removed it and when I plugged it back in the following day it didn't work and it's never worked again. What's more, I had to sign up for their "Premium" offer with no option the first time just to access the app. They give you a 1 week trial period where you can cancel before being billed, but since the app won't detect the device now, I have no way of accessing my account to cancel "Premium", even by going to their website.

I've also used this to enable Video in Motion on a S3 and a S8, it's paid for itself for just being able to do that.

The rest of the functionality requires that you buy the Bluetooth adapter for another 44,90 EUR. Things like removing the iDrive disclaimer. A minor observance, I also think the UI could be updated. Seems a little dated.” – 2/5 in Play Store

A Google user: “Powerful app in that it can do a lot of coding that others can't. However, compared to other solutions which also use the model of wireless adapter and mobile app, Carly's connection between car and adapter is fragile and finicky. Further, the user interface is much worse than its main competitor, and it's more expensive. I bought this thinking that after years of development, the GUI would have improved, but no.

It also displayed some possible future issues and a chance of needing to be replaced as well as general costs for replacement. The only issue I have had with connection to my phone was when trying to connect while it was scanning the vehicle. I read afterwards that doesn't work well. So I wait until after the scan is done and have no issues with it connecting!” – 5/5 in Play Store

Was told my 2002 honda accord would be supported but I paid for the software package and the download kept failing and would and I could not move forward with diagnosis.

I may try to switch phones if I have more trouble. I bought a mainstream phone a few years ago just to run one app on. So I don't just blame the app. It might be my phone.

A Google user: “Absolutely love the app but would greatly appreciate the ability to add more than the maximum amount of 8 gauges to the screen I would like to be able to view at least 10 digital gauges on one screen. I also would find it very helpful if it would give the the option of audible warnings instead of red numbers.” – 4/5 in Play Store

A Google user: “First and foremost, the app does its job. However, it needs simple customizations. I prefer the gauges layout, but every time I start the app, I have to choose gauges. Why not have the ability to make the gauges layout the default? Ability to change color theme? Option to have more but smaller gauges (like the app Torque allows)?” – 4/5 in Play Store

A Google user: “This is the best generic android based OBDII scanner for gathering data. I use it to correct OBDII issues on vehicles that fail their bi-annual smog inspections. Mode1 is able to display all SAE generic pids available in the PCM. When it can, Mode6 CID are translated. Mode9 shows In-use performance tracking. When Permanent Codes are displayed, it shows number of Warm up Cycles, and Miles traveled after code clear. Very useful with the current California smog inspection. If I had a wish list, it would be for better graphing of pids. I use a different application for graphing pids. All in all, this is an exceptional scanner app.” – 5/5 in Play Store

A Google user: “The most extensive ODB2 app on Google Play. I found no other app that can get all the advanced codes like ABS, AWD, and even the Bose amp faults like this one can with the Nissan addon. It was well worth the $15 for the app and addon, as a comparable handheld scanner costs many times this. I can even track the reading of my wheel speed sensors (one of which caused my ABS light to stay on) in real time. And one small issue I had was QUICKLY addressed by support. This is the OBD2 app you need!” – 5/5 in Play Store
