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.

Comments on OBD Fusion (Car Diagnostics) for Android
★★★★★Roby· Aug 7, 2025
The BEST OBD app so far, the more complex and professional one. Torque pro is just a toy, I'm coming from Car Scanner paid who can't connect to enhanced diag, and also tested the Motor data obd just to discover that OBD Fusion found 3 times more enhanced pids for my car...I'm still in shock. Fast connection with a simple Elm327... Can even measure m/s2 acceleration in real time just as Perfecter Dino. I don't get so many bad reviews... App + enhanced diag for my Ford Focus, 24 euro. Highly recommended!!

This is an excellent diagnostics tool. It works well with my Gate iCar Pro OBD II Bluetooth scanner. It diagnosed many issues with both my current car and my old car.

Keeps disconnecting from Bluetooth OBD2 dongle, have used this app for many years but now all of a sudden it keeps disconnecting from the dongle. They don't go works with other OBD2 apps but for some reason it quit working with this one. It will connect I'll start to try to read codes, and then it disconnects every time. Makes it unusable.
★☆☆☆☆Claudi· Sep 6, 2025
Very disappointed. I have purchased the app and the enhanced package for a Ford UGA 2008 because I wanted to get DPF-related readings. Money wasted for nothing, because I can't drop any of the DPF PIDs into the dashboard.
★☆☆☆☆Erik P· Dec 24, 2024
App sucks it keeps disconnecting won't allow me to read the gauges for more than 30 seconds. Constantly stops working. Half the time won't even connect. It sucks.
★☆☆☆☆Teh Operator· Apr 10, 2025
Ripoff of the OBDLink app. 100% clone. Just by the OBDLINK MX+ and you get ALL ADD-ONS for FREE!!! I'm not sure how this is legal, and I want my money back.
★★☆☆☆Christos Mantzavakos· Oct 18, 2025
Unfortunately, it cannot connect when Android Auto starts. You have to connect manually every time. The only reason I chose it is because of the route recording and that doesn't work because it's boring to connect manually every time.
