The app

Final OBD, screen by screen

We’ve rebuilt the whole app for version 8. It reads faster, explains things more clearly and has new screens for what’s going on inside the engine. These are the real screens, with a Škoda Karoq plugged in.

  • An OBD adapter and your mobileAndroid or iPhone, with any of the usual Bluetooth or Wi-Fi adapters.
  • Every control unitEngine, gearbox, brakes, airbag, climate, body and whatever else your car has.
  • Explained in plain wordsEvery fault and every reading comes with what it means, in six languages.
  • Free or ProFree covers the engine, as the standard allows. Pro, a one-off payment, covers everything.
Final OBD menu with a Škoda Karoq connected: Faults, Log, Cockpit, Inspection monitors, Buy or sell report, AI chat and Diagnosis with an expert
The menu, with the car connected. Everything starts here.

With the mobile upright

The screens you’ll use every day

Your car, faults, ITV, data log and settings. This is how they look with the car connected.

  • Your car, Turbo and intake tab: requested and actual boost pressure, atmospheric pressure, air flow and air temperature
    Turbo and intake: what the control unit asks for and what the turbo delivers.
  • A data card in Final OBD: absolute boost pressure, 1.70 bar, explained in plain words
    Tap any reading and it tells you what it is and what values are normal.
  • Faults screen: 1 active, 20 control units read and 4 stored; the P2459 for the particulate filter explained
    Faults from a real Karoq: 20 control units read, one active and four stored.
  • Faults by control unit: Body with one stored and Parking with one active, in red
    Red, failing now. Amber, stored. Green, no faults.
  • Inspection monitors: 9 of 9 complete, with the mileage and engine starts since the last clear
    9 of 9 monitors complete and the distance driven since the last clear.
  • Misfire monitor card: complete, what it watches and the most common faults
    Every monitor explained: what it watches and why it might not complete.
  • Log recording: 16 seconds and 581 readings, with revs, load, temperatures, turbo and speed
    Recording: every reading with its time stamp, one by one.
  • Final OBD Settings: language, connection status, adapter, reader and version
    Settings: language, adapter and your version.

With the mobile on its side

The Cockpit

Turn your mobile sideways and you’re into full-screen gauges. There’s one for each job.

  • Cockpit selector with all its screens: Off-road, Driving, Circuit, Particulate filter, Engine, Electrical and Hybrid
    Every Cockpit screen, all in one place.
  • Driving Cockpit: needle speedometer and rev counter, coolant, oil, oil pressure and turbo
    Driving: needle gauges and the engine readings that matter.
  • Circuit Cockpit on track: revs with shift lights, speed, G force, sectors and the circuit layout
    On track: shift lights, sectors and the layout with your position.
  • Off-road Cockpit: 7 degrees of side tilt and a 13 degree gradient, with gearbox oil, coolant and turbo
    Off-road: side tilt and gradient, with the car drawn on screen.
  • Injectors Cockpit: correction for each injector on a four cylinder engine, with an x-ray view of each cylinder
    Injectors: how much the control unit corrects each cylinder.
  • Knock Cockpit: ignition retard due to knock on each cylinder, in degrees
    Knock: how many degrees the spark is retarded on each cylinder.
  • Turbo Cockpit: actual pressure 1.99 bar and requested 2.87 bar, with a graph of the last few seconds
    Turbo: actual and requested pressure, with its graph.

Getting started

Four steps and you’re inside your car

  1. 1

    Plug in the adapter

    It goes in the OBD socket, nearly always under the steering wheel. It doesn’t matter whether the engine’s running or just the ignition’s on.

  2. 2

    Open the app and connect

    Final OBD finds the adapter, pairs with it and recognises your car on its own. Next time it already remembers it.

  3. 3

    Look at whatever you like

    Data, faults, ITV or the Cockpit. Each screen only asks the car for what you’re looking at, so it stays quick.

  4. 4

    Works without internet too

    Standard OBD is read right there on your mobile. With internet, it also recognises every control unit for your make.

See inside your car this very afternoon

A cheap OBD adapter, the app on your mobile and five minutes. And if you don’t have an adapter yet, the app comes with a demo of a real car so you can see it all first.
