OBD Fusion (Car Diagnostics)

OBD Fusion (formerly TouchScan) is an app that allows you to read OBD2 vehicle data directly from your Android phone or tablet. You can clear your check engine light, read diagnostic trouble codes, estimate fuel economy and much more! OBD Fusion has a ton of features that are used by professional car mechanics, do-it-yourselfers, and users who want to monitor car data during day to day driving. Some of the features include customizable dashboards, real-time graphing of vehicle sensors, emission readiness status, data logging and exporting, oxygen sensor tests, Boost readout, and a full diagnostic report.
Is your check engine light on? Do you want to monitor fuel economy and usage in your vehicle? Do you want cool looking gauges on your Android phone or tablet? If so, then OBD Fusion is the app for you!

OBD Fusion is a vehicle diagnostics tool that connects to OBD-II and EOBD vehicles. Not sure if your vehicle is OBD-2, EOBD or JOBD compliant? See this page for more information: https://www.obdsoftware.net/support/knowledge-base/how-do-i-know-whether-my-vehicle-is-obd-ii-compliant/. OBD Fusion works with some JOBD compliant vehicles and in some cases requires modifications to the connection settings in the app. Please contact us for more information.

You must have a compatible scan tool to use this software. For recommended scan tools, see our website https://www.obdsoftware.net/software/obdfusion. Please note that cheap ELM clone adapters can be unreliable. OBD Fusion can connect to any ELM 327 compatible adapter, but the cheap clone adapters tend to have slow refresh rates and might disconnect randomly.

So far they got me for $20. Can't seem to get the app to connect. Haven't been able to use it once. Rip off artists.

App helped diagnose error codes and performance issues...wotlrth the $$$!

J.. W. Jun 28, 2020     

Update: I have once again found a fix. I turned off mobile data. I have it connecting 3 out of 3 times. Update: I am once again unable to connect to my wifi OBD2 device. I am still able to connect with different software (Car Scanner), so I don't think it's entirely a hardware issue. Ok, so following the instructions imbedded in a different app (OBD Mary), I found that by disabling battery optimization I could get it to work every time. You may want to include this information in your app.

This app is amazing! It worked out of the box with my cheap ELM 327 bluetooth device I paid 15 bucks for, plus 5 bucks for the app and 11 bucks for the enhanced package for Toyota. For little over 30 bucks I have complete live diagnostic data for my car. ABS, transmission, engine.. you named it. No subscription required. I double there is a more affordable option out there. Highly recommended!.

After latest update just keeps cycling through protocols and won't connect

So far so good. 17 Altima, discovered a bad O2. Torque Pro couldn't do that. Thank you.

Compared to others, this is more advanced very customizable.

Joh. Feb 20, 2022     

Very unhappy with this app and how it works on my device as it does not adjust the screen plus I cannot scrool the pages. I wasted my money and wish I can get a refund.

Rob. G. Feb 15, 2022     

Just avoid this app. They got me for $5, then anytime you want to use on a different vehicle you have to PURCHASE AGAIN the "enhanced options". They got me.....so I get to leave this review, don't let them get you too. This app will nickel and dime you all day long.

This app has worked great with my Veepeak obdii dongle. It reads codes, and resets them in all of my jeeps with no problem. Great app.

pri. p. Feb 13, 2020     

App is good, I've even paid for the enhanced diagnostics. I love using this app. However I was in the middle of nowhere, app refused to connect without validating the app. I had no internet access. This needs to be fixed asap. If there is no internet, at least allow the app to run in normal mode.(temporarily disable the enhanced diagnostics). Also my OBD adapter is WiFi, so the enhanced diagnostics randomly get enabled please fix it.

Works well except for fuel usage and efficiency calculations. When the vehicle is idling, the indication is 0 l/100km. This leads to inaccurate fuel efficiency calculations because the average fuel efficiency actually "improves" the longer the vehicle idles. Update - I will check this again and reevaluate my rating if the app works as the developer indicated. The fuel efficiency calculations do seem to be working correctly. One star left open because the MAF sensor indicator always reads "0".

App Will not connect unless engine is running. Then when you go to read the DTC's a message pops up advising that you may want to turn the engine off because it may interfere with the engine. I turn the engine off but keep vehicle in on position and it disconnects. The only way to connect is with engine running. Requested refund through google play. If this is corrected I may return and buy it again. Also the app didn't have an in app search for BMW DTC p1112. The free app did.

Helped me figure out that I have a cylinder 3 misfire. Edit: I understand it might be a little difficult to implement something like this considering all the different car models, but along with the error codes have a small list of possible things to look into. in my case because of the misfire of cylinder 3 replacing the air filter because the fuel was too lean help to alleviate most of the problem.

i use a generic elm and bafx adaptor. both work fine. but I had to go into settings/pref/comm to select the specific bluetooth listing it did not find the paired adapter, even if it was the only one. the software is good and seems very complete. intuitive to use. I wonder if you can program tpms or force a regen on my sprinter Also does it reset limp home mode situations? It offerers me $9.99 options for my 2016 Tacoma but not for my 2016 mb sprinter.

Seems decent, have connectivity problems sometimes but pretty good, I bought the extra pack for my vehicle ( 17,maxima)

Perfect app to use with an bluetooth OBDII reader. A lot more detailed info than your average scanner. Used it, amongst other things, to diagnoze a high pressure fuel pump failure on a Mini Cooper. Saved a wad of cash on that one! Definitely recommended.

Fra. H. Feb 11, 2021     

I am using this with the Kobra OBD2 Android Bluetooth device. This Fusion app will not connect to it. I've gotten free apps to work but of course when I pay for an app it doesn't work. This may work fine for your device though. I wish they listed devices this app is compatible with. I spent a few hours troubleshooting and tried every which way to get a connection.

Joh. H. Dec 4, 2019     

I have to rate this great app with 1 star. The reason relates to its licencing which relies on access to the network. A lot of my travels in Australia are remote with no network. This means the app becomes unusable/useless. If you want 100% usability buy a scanguage.

Gav. J. Oct 31, 2018     

Excellent app, works well with E36, E46 and E83 and looks great too, have been using for years. Try trial version first with your adapter, if it doesn't work, try another adapter.

THE BEST! Have this app for about a year. The ability to customize the gauges and screens is nearly unlimited. Access to every sensor on my L5P Duramax. UPDATE: Well over a year with this app and still thinks it is great.

big learning curve but once I got the hang of it found there was a great range of optional styles and sizes soon found a instrument style that suited my needs. Overall very pleased with the app

Mic. K. Dec 23, 2021     

Just spent $49 for enhanced so I could check ABS on 2000 f350...worthless! Have ABS light on and no reading.

It's good app but expensive to buy advanced diagnosis, for each brand needs to add 300usd extra...., which is unfair
