Finding the Right App: Compatibility Challenges
While the Kobra OBD2 Scanner boasts compatibility with a wide range of apps, the reality proved more challenging. Many popular OBD2 apps are designed to work exclusively with their own branded scanners. After testing several apps, “Car Scanner ELM OBD-2” on the iOS App Store was the only one that successfully connected to the Kobra scanner via WiFi. Most other apps primarily support Bluetooth connections.
