Forthcoming iPhone & iPad
Vehicle, M.D.
A clearer picture of
what drives you.
Clear diagnostics, live dashboards and a garage that remembers.
The all-new successor to OBD2 Expert.
Version 1.0 is being prepared for release.
Beyond the warning light.
Read trouble codes and the conditions behind them.
Make the data yours.
Build dashboards. Record a session. Look back later.
A garage with a memory.
Keep vehicles, scans and recordings together.
Read the clues
A code is only
the beginning.
Stored, pending and permanent trouble codes, with explanations where available. Freeze frames show the sensor readings captured when a fault occurred, while readiness monitors tell you which emissions checks have completed.
The scan stays with the vehicle, ready for your next look or a conversation with your workshop.
Follow the signals
Your dashboard.
Your questions.
Choose the readings that matter to you and arrange them as gauges, numbers or charts. Engine speed, coolant temperature, fuel trims: the vehicle supplies the data, you decide how to see it.
Record a session and revisit its graphs later, without keeping an adapter connected.
Make yourself at home
More than
a generic car.
Give each vehicle its own place in your garage, with its scans, recordings and notes. VIN identification helps fill in the details.
Choose a stock illustration and a paint colour, or use your own photo. Cars, convertibles, pickups, motorcycles and more: your garage should feel like yours.

Take the findings with you
A useful record for your workshop.
Turn a saved scan into a PDF diagnostic report. Share it, print it or keep it with your maintenance records — with vehicle details, trouble codes and the diagnostic data the vehicle supplied.
Coming in version 1.0
Try it first. Keep it simple.
Explore the included sample data before connecting an adapter. The app can be tried for free; a one-time in-app purchase unlocks live data from an adapter and removes the limits on saved vehicles and scans.
One-time purchase. No subscription.
What you'll need
iOS or iPadOS 26 or later, an OBD2/EOBD-compatible vehicle, and a supported Wi-Fi or Bluetooth LE diagnostic adapter. The adapter is sold separately. Online VIN identification requires an internet connection.
Support & adapter compatibility →What your vehicle can tell you
Available readings depend on your vehicle and adapter. Additional UDS/KWP fault data from supported control units is shown separately; coverage varies by vehicle. Not every ELM327 adapter is compatible.
Trouble codes are clues, not a definitive repair diagnosis. Clearing a code does not fix its cause. Use the app only while safely parked.
Screenshots show a development build using sample data and a vehicle simulated with ECUmulator. Appearance and features may change before release. Tap any image for a closer look.
