Worked fine in the past (paid version) on a Nissan Navara D40, built 2012 (Frontier), now after many trials to reconnect it, unfortunately doesn't work anymore,despite recommendations to set up Android phones specifically. It 's a pity...
I was looking for a replacement for Dash. this seems like the perfect one. logs trips, connects to the adaptor easily.
This is my first time trying this app. I like it as it is simple to use , very easy to connect to the OBD Adapter and most importantly it provides all the information I need in a simple to understand format. Thank you very much.
This works great on my 2014 Honda with wifi OBDII sender. Most other apps of this type will not connect. Impressed with the free version. Recommend.
Easy to use and even the free version ist working fine. I mean even to buy the full version 15€ ist nothing.
Connecting to obd2 is fast and stable, lots of adjustable options, error explanations, fuel consumption current and average, just what I needed. Perfect ratio of free options and a pro version if you need more. Thank you, this is 5 stars for me.
I fully understand that on free versions of Apps there is advertising but this app literally throws an ad up every time you try and do something. It became tedious to the point of unusable. I've removed it from my phone.
Very easy to use should include ram 1500 ecodiesel. I tried another app and would not reset my engine light . This one did it on the free version. I will be purchasing the pro version soon . I need to get acquainted with it. I have never used an obd before and this one is perfect for me so far.
Useless. Completely incapable of pairing with a standard OBD2 Bluetooth reader. The same OBD2 sender paired instantly with Torque Lite. So this app is definitely the problem.
Very handy, and easy to use. Excellent for your own diagnostic before taking it in to the garage, or seeing if you can't fix yourself.
Very easy to use and works with my Wi-Fi vLinker MC OBDII connection.
Quick and easy connection to the cheap obd2 device.
Simple to connect to car, lots of information available from the car!
Works like a charm and it's simple to use! I have other more expensive apps that do more but are a pain to get setup! This app is just as good if not better because it's streamlined and everything is ware you expect it. I have the unpaid version but for 8 bucks it sounds like it will do more than the $35 apps. So far it does everything I need some I'm happy!will buy the paid when finished typing this
It worked well until I purchased the full application. It now no longer reads error codes and it starts to go like it did previously and goes to 1% and stops please help
I could read lot of information from (Octavia) like error codes, pressure, temperature, air flow…., and present it on dashboard, in graph.. Looks simple and professional
This app doesn't read a lot of codes on common cars even though I have the payed version so im not happy. Have had other apps with the same ELM reader over the years that were free and worked much better but I cannot get them on my new Android. Also found it tries to run in the background of my phone even though you close the app and heats my phone up and drains the battery twice as fast. So unless you do a forced shut down it cooks your phone. And has no permission options to change settings.
Canging my review. A few weeks ago I wrote: "Turns out the app works just fine, I had an issue in the car which is not the fault of the app. It is very good and love it" Well, not it's January 2021 and I am not in love with it anymore because it might take me 30-40 or more attempts to connect to the hardware in my car before it actually connects. At this stage it's useless for me. Plug, unplug, check bluetooth and pair and unpair, start and restart the app etc etc etc. Waste of time. Maybe the app needs to be updated/upgraded?
It's actually convenient and very easy to use
Very useful for checking error codes! :)
Easy to use and clear obd reader but they will send you an offer in app that if you answer a few feedback questions and give a good rating that they will unlock the app and give you full access. This is a lie. I answered the questions and initially provided a good rating bc the limited features provided work and it was a good offer for full access. But you don't get the benefits of a high rating when you mislead your users.
Connected to the ELM device. Even though it was the full version still failed to read the diagnostic codes "can find app for that function" what was the point of putting that button on the screen. This app is appears to be more of an extension of the cars dashboard.
Easy to use and accurate
this app refused to quit when I chose to quit all my apps. there's no obvious way in the app itself to quit. and it continues permanently to display an icon in the top-left of my Android screen with no way to remove it without uninstalling the program which is what I'm going to do right now. I highly advise not using this program unless you prefer to have this program running permanently on your phone.
Bought the full version because it had a lot of features. Downside is that it uses a lot of battery. It's constantly on in the background and draining the phone. Can't find a way to stop that apart from a restart of the phone. Fix the battery drain and will be a good app
Very easy and simple to use
Connected via Bluetooth without problem and presents a huge amount of data. There are ads but I didn't find them too intrusive. I've not found if it's possible to save data to file for future reference which would be really useful, but that aside it does everything I need, and more.
