The dongle is half the tool; the app is the other half · review
thinkcar ThinkDiag Mini review
An adapter that behaves like a scan tool: the maker states an all-system scan with inspection reports, which is a different proposition from a code-reading dongle.
The last word A scan tool without a screen. The app is the risk and the reason.
What lands on the bench
A Bluetooth adapter and the manufacturer’s own app, which together perform a scan across the car’s control units and produce a report.
Why this is not an ELM327
A generic adapter speaks the standard, and the standard covers emissions-related engine data. Reaching ABS, airbag and transmission needs manufacturer-specific protocols, which is what a tool like this implements and a €15 clone does not.
Where the value is clearest
Buying a used car. A ten-minute all-system scan in the seller’s driveway lists stored faults across every module, and that is information no test drive gives you.
What is not published
The long-term terms of the app. On a tool whose entire capability lives in software, the license is the specification — and this listing does not state it.
Availability
Not found on the American Amazon store, where the buy link falls back to a local search rather than to a page that does not exist.
Prices and availability are what Keepa reported on the date this page was updated; both move.

Tied to one manufacturer app, so the tool is only as good as that app remains
The listing does not state which functions stay free after the first year
Exclusive ThinkDiag app, stated to unlock all functions
Reports
Automatic vehicle inspection reports, stated

The questions that reach us
What is an all-system scan worth?
It reads every control unit the car exposes rather than the engine alone, and produces a list. For a used-car inspection that list is the whole point: it shows the faults nobody mentioned.
Is the app free?
The maker states that the exclusive app unlocks all functions, and does not state what it costs after purchase. That is the question to settle before buying — with any app-driven tool.
Our score

A scan tool without a screen. The app is the risk and the reason.

For BimmerCode and MotoScan · Bluetooth 4.0 · iOS, Android and Windows · BMW motorcycles from 1998 stated
A coding adapter rather than a diagnostic one: officially recommended by BimmerCode and MotoScan, and the one BMW owners buy when they want to change what the car does rather than read why it complained.
Best for: BMW and Mini owners who want to code options, and BMW motorcycle owners using MotoScan.
Bluetooth 5.1 · made for BimmerCode · advanced sleep mode and overvoltage protection · OBDLink app included
The adapter built for coding and safe to leave plugged in: Bluetooth 5.1, an advanced sleep mode, overvoltage protection, and its own app included rather than sold separately.
Best for: Anyone coding a BMW or Mini, and anyone who wants an adapter that can be left in the socket.
ELM327 · Bluetooth Low Energy 4.0 · iOS and Android · power-saving mode stated · works with most OBD apps
The adapter most often recommended for iPhone users, and the one whose listing names the thing that matters when a dongle lives in the socket: a power-saving mode.
Best for: iPhone owners, who have far fewer working options than Android users.
