OBD Fusion supports all OBD2 and EOBD vehicles sold worldwide.

don’t waste your money on this app.
Purchased specifically for an SRS fault, read the information which indicates that it was able to do this and it doesn’t. It indicates that you have to purchase additional functionality that it is suitable for my vehicle it wasn’t thus the app is useless and a waste of money no refunds and that’s why you have to pay up front just to download it don’t waste your money on this app.
Rubbish
Just purchased Fusion and I thought it was Full obd 2 reader but seems I have to purchase more add ons to get more diagnosis info per car forget it
ABS and VSA codes on Honda Civic 2008 - didn’t read codes
I have ABS and VSA codes on my Honda Civic 2008. The app didn’t even register them despite it flashing in my face on the dashboard! Wasted £8.99…
Buy a proper diagnostic tool!
Won’t connect
Connected via Wi-Fi but app keeps timing out on connection so whilst iPad is connected the app won’t. Left with a useless piece of plastic and an app that’s pants
Just monitoring
useless, download a free app
A good App
This App work well.
Great
App works, still didn’t find issue as you can’t run diagnostics with engine on but fault is only when engine is on.
Does not show any codes even though EML illuminated
Having problems with my car, engine management light is on. Connected my OBD and app; connected fine. Zero codes picked up. Just had to pay £95 to have it properly diagnosed at garage, which bought up 4 codes. Save your money and go to a garage. Some things are just best left to professionals.
Doesn’t pick any code. Used to be great
This app used to be great in identifying fault codes accurately and deleting them. Now since the update, and they charged about £10 for continued usage, or doesn’t pick any code whatsoever, although my car dash shows there is fault.
Really bad to charge for something that doesn’t even work.
I need refund
This not work in my car i try nany times and not work, i jnow my car its old but no list wich cara qork
