Smartphone-Based All-System Diagnostics for Android and iOS
The ThinkDiag All Systems Pro Tool is a compact Bluetooth diagnostic tool that turns your Android or iOS phone or tablet into a capable full-system scan tool. It is designed for users who want deeper diagnostics than a basic OBD2 code reader, without needing a large handheld tablet scanner.
With full-system diagnostics, live data, maintenance functions, bi-directional testing, and flexible software options, the ThinkDiag is a practical choice for DIY users, enthusiasts, and light workshop use. It is especially useful if you want strong diagnostic coverage in a small tool that can be kept in the glovebox or workshop drawer.
Best Suited For
The ThinkDiag is best suited to users who are comfortable using a smartphone app and want access to more than basic engine fault codes. It suits home mechanics, mobile users, and workshops that need a portable second tool for quick checks, fault finding, live data, and service reset work.
It is also a good option if you work on different vehicle makes but do not want to buy a larger diagnostic tablet straight away. The software system gives you flexibility, with one year of full manufacturer access included and optional renewals after that.

System Diagnostics
The ThinkDiag provides access to multiple vehicle systems, including engine, transmission, ABS, SRS airbags, body control systems, and other supported modules. It can read and clear diagnostic trouble codes, display live data, and help identify faults across systems that a basic engine-only scanner cannot reach.
For supported vehicles, the tool also allows bi-directional testing. This lets you command certain components or systems from the app, such as door locks, windows, fans, or other actuators, helping confirm whether a component or circuit is responding correctly.
Service Functions
The ThinkDiag includes a range of maintenance and reset functions used for common servicing and repair work. Supported functions include oil service reset, ABS bleeding, DPF regeneration, injector coding, TPMS reset, battery reset, throttle relearn, steering angle reset, sunroof reset, and immobiliser-related functions.
Software access is subscription based after the included first year. Yearly manufacturer software is currently listed at $39.95 USD, and yearly maintenance software is currently listed at $49.95 USD. If the subscription is not renewed, the tool can still be used for lifetime basic OBD2 engine code reading and clearing.
Vehicle Compatibility
The ThinkDiag supports a broad range of OBD2 vehicles across major American, European, and Asian manufacturers, including brands such as Audi, BMW, Ford, Honda, Mercedes-Benz, Nissan, Toyota, Volkswagen, and more.
It is designed for vehicles fitted with a standard 16-pin OBD2 diagnostic port and is app-based, so you will need a compatible Android or iOS device to use it.

Is This the Right Scan Tool for You?
The ThinkDiag is a good fit if you want a compact all-system scan tool that works through your phone and gives you more capability than a basic OBD2 reader. It offers strong diagnostic access, useful service functions, live data, and bi-directional testing in a small wireless package.
If you prefer a standalone handheld tool with no app dependency, one of our dedicated tablet or handheld scan tools may be a better choice. But if you are happy using your phone or tablet and want a flexible diagnostic tool with broad coverage, the ThinkDiag is a smart option for the price.
