Finding the “best” and “low cost” OBD2 scanner that seamlessly pairs with your smartphone can be tricky. Many car owners are looking for a reliable way to diagnose car issues themselves using their iPhones or Android devices. While cheap ELM327 based OBD readers are readily available, compatibility and features vary significantly. Let’s break down the options to help you choose the Best Smartphone Obd2 Scanner for your needs without breaking the bank.
For basic car code scanning on a budget, an ELM327 OBD2 reader is often sufficient. These are knockoff devices widely available online and are compatible with various OBD2 apps. However, they typically don’t come with dedicated software and iPhone users often face Bluetooth connectivity issues with these readers. For iPhone, Wi-Fi enabled ELM327 scanners are generally recommended as a workaround.
If you need more than just basic code reading, consider options like the BlueDriver Scan Tool. While more expensive, BlueDriver offers significant advantages. It provides in-depth code scanning and even suggests likely faulty parts based on the error code. BlueDriver uses its own dedicated app, known for its user-friendly interface and valuable repair reports. Although it’s not compatible with third-party apps like Torque for Android, the BlueDriver app’s features often justify the investment, potentially saving money on unnecessary repairs by pinpointing the problem accurately.
For car enthusiasts and those needing advanced data monitoring, the OBDLink MX+ is a top-tier choice. It excels in data speed and offers enhanced diagnostics, including manufacturer-specific error codes. The OBDLink MX+ app provides real-time data monitoring and, unlike some competitors, now includes previously paid enhanced features for free. While the user interface for accessing these advanced features can be a bit unconventional, the depth of diagnostic information available is impressive.
Keep in mind that OBD2 readers primarily “read” data and reset error codes; they generally don’t allow for changing vehicle parameters. When choosing a smartphone OBD2 scanner, consider your phone’s operating system, desired features, and budget. While “best” is subjective, understanding these options will help you find the most effective tool for diagnosing your car’s health right from your smartphone.
