If you're not sure whether your vehicle is OBD2 or EOBD compliant, see this page for more information: https://www.obdsoftware.net/knowledgebase/obd2compliant. OBD Fusion can also connect to some JOBD vehicles that don’t support standard OBD2 protocols. Electric vehicles (EVs) are not required to have OBD2 diagnostics since they are emissions exempt. If you are interested in using OBD Fusion on an EV, contact us first to inquire about support. OBD Fusion has a ton of features including: - Read and clear emissions-related trouble codes (fault codes) and your Check Engine Light (MIL)
 - View vital driving information on your CarPlay screen. Note that real-time gauges are not supported by CarPlay, so you can't view your OBD Fusion pages such as dashboards on CarPlay. - With optional enhanced diagnostic add-ons, you can read and clear enhanced trouble codes on other modules such as ABS, SRS, etc. and read transmission temperature. An enhanced diagnostic add-on is required for this functionality. - Real-time dashboard display with fully customizable gauges.

    The only thing I wish it had was a more robust CarPlay interface. I wish I could see the same gauges in CarPlay that I can in the app.
  • False description

    Paid 10 dollars for this app as it said it would read abs codes. Get into the app and it has no option to read abs code for bmw. Baited in by a false app description and wasted 10 dollars!
  • Still can’t believe how long they have supported this app. And it’s still my favorite.

    Ive got this and a BlueDriver and still like this better even tho the BlueDriver was $100. Have had this for a LOT of years it’s incredible how well they have kept it updated and efficient. 10 out of 10
  • Some PIDS only

    Needed PIDS for trans fluid temp which worked well. Also working on my ac system. needed PIDS for AC mag clutch on/off. Am able to choose the ac mag clutch but the PID stays in the “off” position and never changes when the ac turns on and off. I could probably keep looking into more of the available data but I’m kinda bummed it didn’t work for everything I needed even after paying for the app and the Toyota Lexus packages. 2015 Lexus GX 460
  • Mazda Extended Support is terrible

    They don’t tell you what extended PIDs are supported until after you pay $15 for the license. I paid to get information to diagnose my AC issues on a 2019 3, and none of the relevant PIDs are even available through this app. No option for a refund.
  • NOT the same as OBD Fusion

    They advertise wrongly that the “OBD Fusion” paid app “contains the same functionality” as this free OBDLink app. Far from it. Explain that there are significant differences where both apps may be required. You got my money for your MX+ hardware over this misleading point. But no high rating.
  • Do not use

    Extremely slow can not get accurate information. Paid 15 dollars to unlock more pids for ford but will still only load half. Not worth it at all
  • Great app!

  • It works

    Back in 2019 I bought a bunch of obd2 apps to work with my elm327 dongle and this was the best one. Fast forward to 2025 and this is the only app that works with my new dongle. It’s identical to the obdlink software except it has more functionality. I drive a Toyota so I don’t need the extended drivers, but I assume that works too. I love it I only wish there was GUI support for CarPlay. Having dials on my dash would be the bees knees. Still though, 10/10
  • Wonderful app, one request

    I used this app to create a drive analysis script that runs through shortcuts, I currently have to auth through Dropbox and download files before I can use them in the script locally If there was a shortcut action to export the csv of the last data logs that would be amazing. Regardless this is an amazing app for what it does.
