Carly — OBD2 car scanner

An OBD2 car scanner that puts professional diagnostics in your pocket, Carly connects to your vehicle's OBD2 port to deliver real-time engine data, fault code readings, and repair guidance — saving car owners thousands annually in unnecessary mechanic visits.

Whether you're troubleshooting a check engine light, monitoring your car's health, or planning maintenance, you gain instant access to the systems that matter most. Read and clear fault codes from your engine, transmission, ABS, and airbag systems. Monitor live engine data to understand exactly what your car is telling you. Follow step-by-step repair guides to fix issues yourself, or use service reset tools to complete maintenance independently — all from your smartphone.

Carly works with virtually every major vehicle brand including Audi, BMW, Ford, and hundreds of others. The app adapts to your car's specific model, year, and technology, so you always get accurate, relevant diagnostics tailored to your vehicle. Start with free features like car history checks and basic diagnostics, then unlock premium capabilities with an annual subscription to unlock advanced repair guides, battery health monitoring, hidden feature customization, and mileage fraud detection.

The Free Car History Check feature lets you investigate any vehicle without an OBD adapter — perfect for used car buyers and sellers. Enter a license plate to uncover detailed ownership timelines, accident reports, maintenance records, safety recalls, insurance history, and true mileage to detect odometer tampering. Know exactly what you're buying or selling before making a decision.

Getting started is straightforward. Check which features your car supports, order the Carly Universal Scanner (backed by lifetime warranty and premium support), connect it to your OBD2 port, and log in. The scanner is engineered for compatibility across most vehicles and designed to work seamlessly with the app's advanced diagnostics.

Choose a subscription for your specific car brand or unlock access across all brands with an annual plan. Manage your subscription anytime — renewals can be canceled up to 24 hours before your billing date.
