-
01 / CONNECT
Plug into the picture.
Connect a compatible adapter to your car’s OBD-II port. Pair it with the app while safely parked.
-
02 / UNDERSTAND
Turn data into context.
See available fault codes and readings, then use AI-guided explanations to understand what they may mean.
-
03 / EXPLORE
Choose your next step.
Prepare for a repair conversation or explore coding options specifically validated for your vehicle.
A fault code is
only the beginning.
Your car speaks in codes and readings. VYNSCOPE is being built to put them in context, so your next question is a better one.
AI can be wrong. Vehicle data and explanations support a qualified diagnosis; they don’t replace one.

A little more knowledge.
A lot more perspective.
Free and open source by design. We’re making the information inside your car easier to understand—and the code behind the app open to explore.
From
“What now?”
to “Now I know

Readings with a reason
Explore supported parameters such as engine speed and coolant temperature, with units and context.
A clearer repair conversation
Use the code, symptom, and reading together to help describe the issue to a qualified technician.
Possibilities that fit your car
Vehicle-specific coding is a planned part of the experience, subject to feature and compatibility validation.
Free software. Open code.

A deliberate change. Every time.
Coding may affect vehicle behavior. Availability depends on model, equipment, control module, and software. Follow vehicle-specific instructions, maintain the required power supply, and work only while safely parked. Some changes may require professional recovery.
The right connection
makes the difference.
The port is the starting point. Your vehicle, phone, adapter, and desired feature all need to work together.

An OBD-II connector alone doesn’t mean every vehicle system or coding feature is accessible.
- Vehicle make, model, year, and market
- Phone platform and adapter connection
- Diagnostic protocols and feature requirements
- Module and software versions for coding
Compatibility validation is in progress.
Initial development targets BMW vehicles with an OBDLink CX.
In-car verification is pending. Please wait for confirmed
compatibility before buying hardware for this app.

Clear answers.
A few things to know before you plug in.
What is VYNSCOPE?
VYNSCOPE is a free, open-source app in development that will connect to a compatible OBD-II adapter to help explain vehicle data with AI. The planned experience combines diagnostics, contextual readings, and vehicle-specific coding where validated.
Will it work with my car?
Support has not been confirmed yet. Compatibility will depend on your make, model, year, market, phone, adapter, and selected feature. Generic OBD-II diagnostic access does not guarantee access to every module or coding function.
Which OBD-II adapter do I need?
You’ll need an adapter tested with the app and your phone. Wireless connection types and protocol support vary. We’ll publish a confirmed adapter list before launch; please don’t buy an adapter for this app yet.
Can AI tell me exactly what to repair?
No. A fault code is a clue, not a confirmed failed part. AI can make mistakes, and a diagnosis may require inspection and tests by a qualified technician. Follow your vehicle manufacturer’s warnings. A flashing check-engine light can indicate a problem that may damage the catalytic converter.
Is vehicle coding the same as clearing a fault code?
No. Coding changes supported configuration settings in vehicle modules. Clearing diagnostic codes removes stored diagnostic information and does not repair the cause. Some changes can affect vehicle behavior and may require professional recovery. Neither capability should be assumed from the presence of an OBD-II port.
When can I download it, and what will it cost?
VYNSCOPE will be free and open source. iPhone and Mac versions are in development; a launch date has not been announced. The initial build focuses on read-only diagnostics and coding backups. AI assistance and vehicle writes are planned. Compatible adapter hardware is separate.
Where can I find the source code?
Follow the app’s development at github.com/smidley/Vynscope. The repository includes the app source and development plans. Check its current documentation for build instructions and status.
