About the app
RaceMeasure LLC · Android
I'm Denis, the developer of CarDiag AI at RaceMeasure LLC. CarDiag turns a check-engine fault code into something you can investigate: available vehicle data, likely causes and a step-by-step diagnostic plan using OpenAI. It reads available fault codes through a compatible OBD adapter, and demo mode lets you explore the app without a car or adapter. Compatibility varies by vehicle, ECU and adapter. There is no coding, adaptation or service-procedure support. Basic diagnosis and demo mode are free; Pro features and AI usage are separately paid. No purchase is needed for this test.
What to test
Help us prepare for public Google Play release with a genuine 14-day Android closed test. No car or adapter is required for the demo/interface tasks. Please remain opted in for at least 14 days and use the app during that period. We want honest criticism and reproducible bugs, not positive ratings. This is an unpaid volunteer test; no store review is required. Install using the SAME Google account on every page: 1. Join https://groups.google.com/g/cardiag-testers-dev/about 2. Become a tester: https://play.google.com/apps/testing/com.racemeasure.cardiag 3. Install: https://play.google.com/store/apps/details?id=com.racemeasure.cardiag If Play says URL not found, check the email under the avatar in the group, opt-in page AND Play Store. The Store can switch accounts automatically. Access is limited to selected countries; report your country and the failing step if it is unavailable. Use the free demo/basic features only. Keep feedback and questions here on Beta Family. Do not share email addresses, VINs, precise locations, login or payment details. Optional screenshots should hide personal information. Beta Family currently accepts up to 20 free reports during a five-day window. Please submit your first honest report during that window; do not wait 14 days to report an installation issue. The 14-day request refers to continued Google Play opt-in and real app use, which is separate from this report deadline. We will not describe an initial report as a completed 14-day test.
