About 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.

The app has been a great help in reading, troubleshooting, and clearing codes. The Monitor saved alot of time and driving when determining if the monitor tests are complete and the vehicle is ready for emmisions testing.

Whole I appreciate the reply, that's not why I gave it a low rating. The reason I gave it a low rating is because you gave us the ability to make custom displays with custom colors and sizes to then make a completely unique Dashboard, but with NO ability to SAVE that dashboard and then LOAD it later. U had a great setup, and now it's gone and I have to start all over sgsin. That's B.S. You have the "Add Dashboard" option, but this function just tells us to use Add Displays. What's the point? There should be a Save Dashboard option, and a Load Dashboard option, and if you're going to have an Add Dashboard button, make it do something other than give me a stupid message to use the Add Displays. Furthermore, I purchased a BaFx bluetooth DLC connector, so I'd say it's hardly a $5 Chinese knockoff. Nevertheless. I'm sure I'm wrong about the PID defaults. That doesn't change the fact that you give people the option to purchase additional data sets for other manufacturers, but only SOME manufacturers like Toyota.

Very useful for determining whether the thermostat had failed on my BMW E92 diesel, far easier to use than faff about unlocking the hidden water gauge in the cluster. Noticed a couple of things about the logged data after exporting to my pc, on most logs I appear to have turbo boost with a no throttle input, secondly it would be great if the app had an export/share logs button that enabled easy location, sharing and also offer of deletion of logs. All in all a 5 star app that with patience gets the information you're after. Well done and thank you.

Does not connect to my scanner. I've tried everything and it has never worked. Wish I hadn't paid for this useless app.

C70%
by C####:

Setup is not intuitive and the actual cost is significantly more than the Google Play Store cost.

K70%
by K####:

If you're looking for something user friendly this isn't your app. Menus don't flow and interface lacks polish. The app really feels like someone's senior college project, only reason I use it is because I paid for it. Two well deserved stars

Great app! I have been using it for a while now. The only thing I would like to see it do is add more manufacturer specific code interpretations. The generic ones do get me in ballpark on VW Beetle. But Im not a great guesser.

by C####:

It wasen't connecting at all... Whatever I did... Luckily after the update, the issues got fixed. The only negative thing is that there is a 1 second delay in the readings. If that could be fixed it would be perfect!

Great app. Could you add a freeze frame of the maximum power and torque underneath the display so that you dont have to take your eyes off the road. Could you also add enhanced diagnostics for MITSUBISHI vehicles.

by C####:

The app is straight forward and a life saver when it comes to saving cash. The only problem i have is understanding how to purchase modes? Other than that this app is perfect!

I paid for the app then paid more for advanced diagnostics. It does not find AND and Brake light error codes.

Just brilliant

Here to say, I believe this is currently the best app out there overall. Checked many apps, and many are great, torque is ugly, bluedriver is overpriced. This has absolutely everything, with a clean UI. and for years it's remained one of the most advanced app in terms of customization, Logging, smog status. Kudos to the developer. I hope he adds more sensors to the logging screen is capped at 4 currently. just bought a new adapter after losing my old cheapo elm327.

It's ok. I upgraded troubleshooting for my vehicle and don't see any additional info for it at all. Kind of a waste of money with that option.

Connects to the wifi for about a minute the disconnects and you have manually reconnect. At least it didn't cost alot, not worth it.

2014 Toyota Camry LE - toyo specific module works well at first test of A/C compressor data. I am impressed for $15 USD. Keep up the good work! I subtracted a star because I had to manually choose the communications protocol before it would connect. Automatic protocal setup failed. But now it is smooth sailing.

C70%
by C####:

I bought the paid version, and I kind of regret it. Not intuitive or user friendly like Torque. Make it auto connect to the OBD reader, make the logs easy to set up, compile, and email or export (Dropbox is so 5 years ago, everyone's on Google Drive), and I'll update/change the review.

C70%
by C####:

Everything works great, the app runs smoothly, but it won't let me select the make and model of my vehicle. Jeep is not listed as an option, and there is no way to de-select a vehicle after choosing one. I had to delete my vehicle and will need to re-add.
