ELM327 is a very popular OBD-II (On-Board Diagnostics) interface chip that allows you to connect your car's computer to a smartphone, tablet, or computer. Because it's a widely adopted standard, many apps support ELM327 adapters. The best app for you will depend on your operating system (Android or iOS) and what features you need. Here are some of the most popular and highly-rated apps that support ELM327:
For Android:
1,Torque Pro (Paid) / Torque Lite (Free): This is arguably the most popular ELM327 app for Android. It offers extensive features for real-time data monitoring, fault code reading and clearing, performance metrics, and a customizable dashboard.
2, Car Scanner ELM OBD2: Highly rated, this app offers a wide range of features including live data, fault codes, freeze frame data, and even some advanced coding functions for specific car brands. It's available on both Android and iOS.
3.EOBD Facile: A good option for reading and clearing fault codes and displaying real-time sensor data. It supports all ELM327 Wi-Fi and Bluetooth adapters.
4. HobDrive: Known for its advanced tracking features, including fuel economy statistics, and compatibility with both OBD2 and some non-OBD2 vehicles.
5.inCarDoc: Offers OBD2 fault code scanning, real-time parameter monitoring, and a detailed logbook.
6. AndrOBD: A free and open-source option for OBD2 diagnostics.
For iOS:
1.Car Scanner ELM OBD2: Also a top choice for iOS, offering similar comprehensive features as its Android counterpart.
2.EOBD Facile: As mentioned above, it's also available and popular on iOS.
3.OBD Fusion: A powerful app for monitoring vehicle sensors, reading and clearing fault codes, and exporting data.
4. DashCommand: Allows users to view, record, and troubleshoot a vast amount of data.
5. inCarDoc: Also available for iOS with similar features to the Android version.
6.GaragePro: This app offers comprehensive OBD coverage, including reading fault codes from all ECUs (Engine, Airbag, ABS, BCM, etc.), and special functions like injector coding and DPF regeneration.
Important Considerations:
1.Adapter Type (Bluetooth vs. Wi-Fi):
Android: Generally supports both classic Bluetooth (1.x, 2.x, 3.x), Bluetooth LE(4.0+), and Wi-Fi ELM327 adapters. Classic Bluetooth is often recommended for speed and reliability.
iOS: Primarily supports Bluetooth LE (4.0+) and Wi-Fi ELM327 adapters. Classic Bluetooth adapters are generally NOT compatible with iOS due to Apple's operating system limitations, unless they are MFi (Made for iPhone/iPad) certified adapters (which are rare and more expensive).
2."Fake" ELM327 Adapters: Be cautious of very cheap ELM327 adapters, especially those marketed as "v2.1." Many of these are poor clones and may have limited functionality or bugs. It's often recommended to invest in a slightly more reputable brand like OBDLink, Veepeak, or Vgate for better performance and reliability.
3.Car Compatibility: While ELM327 adapters work with any car that supports the OBD-II standard (most vehicles built after 1996 in the USA, 2001 for gasoline cars in the EU, and
2003 for diesel cars in the EU), the level of detail and specific functions available can vary depending on your car's ECU. Some apps also offer enhanced features for specific car manufacturers.
Before purchasing a paid app, it's a good idea to try a free version or a trial to ensure compatibility with your specific ELM327 adapter and vehicle.
