Compatibility and Adapter Recommendations
Car Scanner supports vehicles using the OBD2 standard, generally those manufactured after 2000 (and some as early as 1996). It requires a compatible ELM327 OBD2 adapter with Wi-Fi or Bluetooth 4.0 (Bluetooth LE) connectivity. Recommended adapter brands include Kiwi 3, Viecar, V-Gate, Carista, LELink, and Veepeak.
Important Note on Adapters: Avoid cheap, generic ELM327 adapters, particularly those marked as v2.1. These often have connectivity issues, bugs, and can potentially cause instability in your car’s engine. Invest in a reliable adapter from a reputable brand for optimal performance.
Pricing and In-App Purchases
Car Scanner is available for free download on the App Store. However, to unlock all features, a one-time purchase or a subscription is required. The free version offers limited functionality, allowing you to test basic features before committing to a purchase.

Its customizable interface, extensive feature set, and broad vehicle compatibility make it a valuable tool for monitoring, diagnosing, and understanding your vehicle’s performance.
