But with so many OBD2 scanner apps available, finding the best free option for iPhone can be challenging. This article reviews Car Scanner ELM OBD2, a popular choice for iOS users, highlighting its features and limitations.

Car Scanner ELM OBD2 offers a wide array of features for both basic and advanced users. Let’s delve into what makes this app stand out:
Customizable Dashboard and Data Logging:
The app allows you to create personalized dashboards displaying real-time data from various sensors, including speed, RPM, coolant temperature, and fuel consumption. This customizability lets you monitor the parameters most important to you. You can also log data for later analysis, helping track performance trends and identify potential problems.
Extensive Diagnostic Capabilities:
Car Scanner ELM OBD2 reads and resets Diagnostic Trouble Codes (DTCs), commonly known as “check engine” light codes. The app includes a comprehensive database of DTC descriptions, enabling you to understand the issue and potentially fix it yourself. Moreover, access to Mode 06 data provides detailed ECU self-monitoring test results, offering further insights into your car’s health.
Performance Monitoring and Emission Testing Readiness:
Beyond diagnostics, Car Scanner ELM OBD2 helps measure acceleration times (0-60 mph, 0-100 km/h, etc.) and track fuel consumption statistics. It also checks your car’s readiness for emission tests, ensuring you’re prepared for inspection. All sensors can be viewed on a single screen for a comprehensive overview of your vehicle’s status.
Vehicle Specific Features:
The app includes specific connection profiles for various car manufacturers like Toyota, Mitsubishi, GM, Ford, and Volkswagen, unlocking additional features tailored to these vehicles. For VAG group cars (Volkswagen, Audi, Skoda, Seat), it even offers encoding functionalities for adjusting hidden parameters.
Hardware Requirements and Compatibility:
Car Scanner ELM OBD2 requires a compatible Wi-Fi or Bluetooth 4.0 (Bluetooth LE) OBD2 ELM327 adapter. Recommended brands include Kiwi 3, Viecar, and Veepeak. The app works with most vehicles built after 2000 that adhere to the OBD2 standard (some models as early as 1996 may be compatible).
Free vs. Paid Features:
While Car Scanner ELM OBD2 offers a range of free features, unlocking its full potential requires a one-time purchase or a subscription. The free version provides basic diagnostics and data viewing, making it a great starting point. However, features like custom dashboards, advanced diagnostics, and vehicle-specific functionalities are often restricted to the paid version.
