FIXD Scanner Review: A Branded ELM327 With an Overpriced App
Published: February 2, 2024 · Last updated: June 4, 2026
The FIXD is a Bluetooth ELM327-style adapter wrapped in a branded app with a paid Premium subscription. I retested it on real cars to see if anything improved. The short version: the adapter itself is usable with other apps, but the Premium subscription is even harder to justify now that free tools like ChatGPT and better scanners exist at the same price. It’s engine-focused, with no coding, resets or bidirectional. Read on for why it failed my tests.
I earn from qualifying purchases and sometimes get tools for free (full disclosure). It never affects my scoring.

What it’s actually good at
As a plain Bluetooth adapter, it works, and that’s the only real positive. The hardware is a standard ELM327-style dongle: plug it in, it connects, LEDs show power. Paired with a proper app like Car Scanner instead of the FIXD app, it does what any cheap adapter does, reads engine codes, shows readiness monitors, graphs live data. The FIXD app itself is also clean and beginner-friendly to navigate.
That’s genuinely where the praise ends. Everything good about it is “it’s a normal ELM adapter,” and the useful things require ignoring FIXD’s own software in favour of a free third-party app.
Where it falls short
The scanning isn’t reliable, even as an engine-only tool. On a 2005 VW I had a fresh ThinkDiag2 full-system scan showing faults across engine, transmission, climate, body, airbag and more. FIXD found only 9 codes and missed some the ThinkDiag2 caught in the engine alone (P0638 was simply absent). Worse, it reported transmission, ABS and airbag as “all clear” when real faults existed. You can’t trust it.
The Premium subscription adds almost nothing, and that’s the core failure. After unlocking it, scanning didn’t improve. The “odometer fraud” check failed on a car where I’d personally changed the mileage as a test. The emission pre-check is just standard readiness monitors any $5 scanner shows free. Live data is a handful of PIDs with no real graphs. And the AI mechanic gives worse answers than free ChatGPT. You’re paying a yearly fee for features free tools already do better.
It’s not a service tool at all: no EPB, ABS bleed, SAS, DPF or battery registration, no bidirectional, no coding. It reads basic engine data and sells you a subscription.
Who should buy this
Almost nobody, and here’s the straight version:
Maybe consider it if:
- You find the adapter heavily discounted and only ever use it with a free third-party app, never the subscription
Look elsewhere if:
- You’re thinking about FIXD Premium, that’s the whole trap, free apps and ChatGPT do more
- You want reliable scanning, it missed real faults on engine and other modules
- You want service resets, bidirectional or coding, it has none

Final word
The FIXD adapter is okay only if you get it cheap and use it with a free app like Car Scanner, ignoring the subscription entirely. As a full product with its own Premium plan, it fails completely. The free app misses trouble codes, the Premium features are beaten by free ChatGPT and free OBD apps, the scanning isn’t reliable even for engine work, and the odometer and buyer’s tools were useless in my testing. For the same money as a year of Premium, buy a ThinkDiag2, a Kingbolen S608, or any good ELM adapter, all of them do more.
