MechaOBD
Smart Diagnostics for Your Car
Free · In‑App Purchases
Stop guessing what’s wrong with your car. MechaOBD turns real vehicle data into clear diagnostics, likely causes, and actionable next steps.
Understand your car. Know what to check next.
A trouble code tells you where to start. MechaOBD helps you put it in context with live vehicle data, guided Health Checks, and diagnostic reports written in plain language.
Download the app for free to scan codes, explore vehicle data, and run Health Checks. Diagnostic Reports are purchased individually in the app. No subscription.
See what your car is reporting
Read diagnostic trouble codes, view available sensor readings, and check emissions readiness information from your iPhone or iPad.
Follow a guided Health Check
Step-by-step prompts walk you through capturing data from your vehicle. Bring trouble codes and sensor readings together for a more useful picture of what your car is doing.
Get a clearer explanation
Purchase a MechaOBD Diagnostic Report to turn a completed Health Check into an AI-assisted analysis that helps you understand:
• Likely causes of the issues found
• The vehicle data supporting each finding
• Suggested tests, repairs, or further investigation
• A summary of your vehicle’s reported condition
Each purchase covers one diagnostic report. You can revisit your saved report without purchasing it again.
Save and share your findings
Keep past reports in the app and export a detailed PDF to review later or share with a mechanic. Bring the findings and their supporting evidence into your next conversation about repairs.
Explore before you connect
Try Demo Mode with a prerecorded vehicle session to explore the Health Check and report experience without connecting an adapter.
What you’ll need
A compatible Bluetooth Low Energy OBD-II adapter is required for vehicle diagnostics and is sold separately. Available data and functions vary by vehicle and adapter. Generating a diagnostic report requires an internet connection.
MechaOBD is a diagnostic aid. Its reports identify possible causes and suggested next steps; they do not replace inspection or diagnosis by a qualified automotive professional.

Bug fixes
• Adapter names in the Bluetooth device list no longer switch to a string of numbers while you're choosing one. The recognizable name now stays put, including after you connect.
Usability improvements
• The first time you open this version, a short notice explains that MechaOBD needs a Bluetooth OBD-II adapter, with a link to adapters we've tested.
• Recommended Adapters is now in Settings under About, so you can find a compatible adapter anytime.
