  • Where is the trans temp gauge

    By Bighoss7274
    I purchased this app for my 2004 Tahoe great other than no way to monitor my trans temp....and that is the main reason for me buying this please fix...
  • No trouble codes detected

    By kennethk70
    Airbag light came on 2003 z4. Followed instructions to connect. Worked very well but diagnostic is saying that there are no trouble codes and mil is off. Please advise.
  • Great app

    By glasspusher
    Used this to replace my old clunky PC based OBD software. Fusion’s tech support worked with me to get a better data acquisition solution for my Prius battery. I am extremely pleased with this software and their support.
  • Outstanding value

    By carranado
    For $10 how can you go wrong works as advertised, I used it at the BMW dealership before buying a used car just plugged it in and got the diagnostic. Wow wow wow $10 coupled with $26 WiFi OBII reader and I’m dangerous
  • Looks like it would offer a lot, but doesn’t support what it says it will.

    By jkistner89
    Says it supports “Micro Mechanic” adapter but doesn’t. Now I’m out $10
  • Good for now

    By 09max
    That’s my first time using this app and it works great but I noticed that there is no transmission monitoring or diagnostic ?? That would be important for me if it can be added in the future because I have a CVT on my maxima and we all know what reputation this transmission has. Even if I’m issue free for now with it, I would really like to have this option available in the app. Thank you, you did a great job.
  • Killer App!

    By wcmrsh
    I own a 2006 Infiniti G35 Coupe and right my check engine light is on due to a fuel sensor needing replacement. The part is not that critical for me to replace at this time. I hate seeing the check engine light on whenever I drive my car. My girlfriend bought me the device that plugs into my car, I download this app and it is pretty amazing with all the diagnostic it provides for your car. The best thing is there’s a button that allows me to shut off the check engine light. Every couple of months I’ve used the product and it works within minutes. I love it!
  • No BMW

    By DKSaul
    Just bought and used on my BMW that has the red error with brake light on, I read several times with the app and no errors found. I then, used Carly app and found 18 error codes. I wish I could get my money back as the app doesn’t work.
  • Great App! One suggestion.

    By milspecj
    I have been using this app since I bought my 2018 5.0 F150. I have been able to data log like crazy and export to Excel to create charts. With a quality OBDII adapter it runs flawlessly. The only suggestion I have is to be able to use with Carplay.
  • CarPlay Please!

    By Carlaughter
    I have been using this app for a while now. I am quite impressed. I am hoping for a few feature requests. First, designing gauges a tedious process, though very versatile. If you add a way to set a style (colors, bezel settings, sizes) that can be applied to multiple gauges, that would make the process easier. Also, a more seamless auto-connect to OBDII would help. And last but not least - CarPlay support!!! I am enjoying it nonetheless - A very nice product.
  • No Support for new Honda Models - Clarity

    By joski
    I was very disappointed to discover that my 2018 Honda Clarity PHEV is not supported by this app AFTER paying $10. Should be more upfront about the vehicles that are supported.
  • Purchased extras

    By Renchster
    Application works well for basics. when you purchase extras you still really kind of get just basics . my application is 2003 excursion with a 7.3 I can’t understand why I can see Ipc pressure , but not Ipr percent this is a great value to monitor during diag. Also Throttle position pod has no values
  • Obd2 Fusion app

    By Dud9930
    This app can be a bit complicated because of the advanced technology within. That being said the customer service is top notch. I’ve been working with Ryan and he’s helped every step of the way! Great app!!
  • Great app. Needs more add-on

    By Jbugge32
    The app works great! Comes with great features out of the box. Easy and simple to use and the live data is accurate and quick! Only reason for 4 star rating is because you can only get advanced diagnostics through in-app purchase for certain manufacturers which I found through searching around on the internet. Other than that. Highly recommend the app!
  • Chevy Ambulance

    By co14firefighter
    Will not connect to a 2013 Chevy 3500 Ambulance using a veepeak ble adapter.
  • It simply works worth every penny. Works with as seen on tv micro mechanic

    By kieros987
    This app is amazing works with my cheap little as seen on tv micro mechanic gave me some real time stats on the engine and gas milage for $30 total i can diagnose and check fuel economy thanks
  • Hard to use. Where is 1/4 mile?

    By Chowabbajack
    I bought this app to use to measure my performance times, as they claim to be able to do in the description. This app is unpolished and not easy to use for a beginner. I was not able to find the appropriate displays for what I want. I'm sure it has a lot of information, but none of it is easy to get to.
  • Need more Pids

    By milmasks
    There’s no Pid for transmission temp for a 06 Chrysler 300. Also can’t figure out how to read fuel pressure pretty annoying!
  • Lexus gx470 transmission temperature monitoring

    By ADM1335
    Very easy once you purchase the extras. Super easy to set up each sensor sensor 1 is the pan and sensor 2 is the torque converter
  • Frustrating...

    By jerzee.george
    This is a frustrating piece of junk software. It worked first time with Kobra scanner. Now even though WiFi signal. No connection. Very difficult troubleshooting instructions. Plug and play anyone???! This was a waste of $$$.
  • Where is the reset button?

    By 76nba
    Reads diagnostic codes OK, but I can not find the button to reset them. I’m a bit disappointed with this. Ad says this feature is included.
  • Great for the $ works on 4S iPhone

    By Jetinjeff29r
    Buy this and and a Blue tooth OBDII reader and your pretty well set. Live data. Switch between OBDII compatible vehicles. It knows which one you are plugged into. Only one I found at the time that did Blue Tooth for IPhone in this price range. Works on my old 4S
  • No customer support or response.

    By burgieman
    This app was recommended by several WiFi dongles so I bought it. It doesn’t cover my 03 Dodge and there is no way to get a refund or a response from the developer. It also consists features that are free in other free OBD apps. Don’t waste your time.
  • Kiwi 4

    By rv6flyer
    This worked great with PLX Kiwi 3 but cannot get it to connect with the new Kiwi 4. PLX is no help at all.
  • Excelente

    By y2krichard
    Muy buena app

    By hoss_87

  • Worst App

    By Wilohw
    Dont work and dont clear the codes worst 9,99 i pay for
  • Not bad

    By jeep mech
    Works fine would like to have the ability to add more instruments Would like to add oil pressure gauge
  • Consistently does not connect to Automatic adapteR.

    By Sardonick007
    Waste of money. Problem still all over the forms OBD fusion does not connect to Automatic adapter consistently seems like a waste of money to me. No estimate of when it’ll get fixed and no remedy.
  • Impressed!

    By Squashhead
    The amount of customization on this app is incredible! You can adjust every little detail on the gauges. I haven’t used it for anything but monitoring every day system performance, but it works great. Connected to my Veepak Bluetooth OBD2 connector without a problem. It’s a great looking app.
  • Can’t reset Maint Reqd light.

    By tdtran1963
    Can’t reset Maint Reqd light on 2006 Toyota Sienna.
  • Get Rich

    By Kcservices
    The best I’ve found so far.
  • Very awesome but not perfect

    By Joe333344joe
    I’m having trouble with the app disconnecting from the OBD link. Also I wish you could drag gauges from one page to another in the dashboard.
  • Doesn’t work on BMW X5

    By Kinerkj
    This app will not clear codes on a 07 BMW X5 4.8i. Code is PO420. Tried to clear it a number of times.
  • Its what you are looking for

    By The_ddub
    I was looking for an app that connects to a low price, non-proprietary OBD dongle and this is it. Its a great app with customizable displays and also reads trouble codes. I was able to set up a dashboard that shows me the info that I want to see and thats what makes this app so great. Its similar to Torque Pro since Torque Pro is no longer supported on iOS. You won’t be sorry you got this app!

    By kroslackmx1
    This device works great! Everything I needed it for
  • A good product that has served me well for years.

    By NotAPreppie
    I like the ability to add custom PIDs as well as the extra ones that can be purchased. My only complaint is the lack of CarPlay integration. Now that iOS 12 is out and CarPlay is open to 3rd parties, I’d love to be able to display this app on my dash.
  • Much better with Veepak than WiFi

    By Daniel4844
    Much easier to connect and use wth Buetooth and map function woks with cell phone data.
  • 1997 Mazda Miata obd2

    By 68421814
    This app works ok. It’s not bad, but could definitely be improved. particularly the powertrain module that I’ve paid for that it will not connect to. As well, there are some glitches when you swipe side to side trying to adjust things. Designing the dashboard is pretty fun but could use some more features and designs. Other than that just totally works with my BAFX products OBD2 diagnostic interface module.
  • B Clayton

    By BK Clayton
    Trouble getting Bluetooth to link with phone. Trying another brand. Many to choose from.
  • Didn’t get it to work right and no one answered my calls

    I’m giving it 1 star bc nonOT HELP
  • Developer did an excellent job!

    By Mlo166_yahoo-com
    The developer thought of everything necessary to allow full flexibility of PID functions, editing formulae, network connections, and display profiles. Now, the app includes moving map types with selectable log types and performance logs, and much more! Wow. I recommend all RV travelers to use this app!
  • Can’t use on multiple cars

    By nativewisdom.net
    This app is good for grabbing codes, but all the rest is just gimmicks. It doesn’t save a drive history like it says and you can’t just plug it into different cars— say you your wife and two kids or whatever. Each time you put it into a different car it asks you to manually reset year, make, model , etc. it won’t let you just save profiles. Payed $10 for the app, then they wanted $10 due to my specific car. I’m not against the app, just warning others that it doesn’t do all that much.
  • dashboard doesn’t read

    By bmwzhp
    app doesn’t actually connect with car. can’t get the real time data from the computer so the dashboards needles just don’t move. should def fix whatever issue this is
  • Seems pretty cool

    By Geddy'sUncle
    Had it in my little Ram1500 ecodiesel only since yesterday. I can now monitor boost pressure, exhaust-gas temps before and after turbo pretty easily. There are a couple dozen other parameters I could watch if I do chose. I haven’t demanded that many additional interrogations and answers, so, I don’t know what it takes to overload it and get slow updates, but, for what I want to watch, this little system seems to work pretty well.
  • Does it work with the new IOS 12.1

    I just purchased this app for my Vgate icar2 elm reader I have a option to update my phone software to iOS 12 so I would like to know if it will work on the new operating system if not I won’t update my phone
  • Know before you go

    By fair shake
    App gives you the knowledge you want before you take your car to the mechanic. Works easy and well
  • Good program, needs some work

    By Jim Worm
    This works well with my OBD2 dongle. The information seems accurate and helped me when buying a used car by showing me the error codes, which I showed the dealer. He then gave us a new battery based on the report with no change in the price of the car. There are a few annoyance. It does not connect with the Bluetooth with out some finagling. Once the phone is turned off, it loses the connection. The data does not seem to be saved. Once I use it on another car, the data for the first car is lost (or I can’t find it). It “forgets” vehicles so I have to to re-enter the information when I change cars. It would be nice to be able to download the information to a desktop for storage. Overall works well for diagnostic information but it would be nice to store each car’s information and be able to reference it later.
  • Wast off $10

    By cbmuth99
    I first downloaded a free app. Thought if I bought one I would have more options and I was wrong 👎🏻
