The coverage on iOS devices may be comparatively less than that on Android devices due to certain factors related to software restrictions and market considerations.iOS, the operating system used by Apple devices, has a more closed ecosystem and stringent app development guidelines. These restrictions may limit the functionality and scope of third-party apps like ThinkCar ThinkDiag. Consequently, the coverage of ThinkDiag features and capabilities may be affected on iOS.The Android platform, being more open-source and customizable, provides developers with greater flexibility in designing and implementing various features. ThinkCar's development team can leverage this flexibility to create a richer user experience and enhance the functionality of ThinkDiag. This focus on Android development is influenced by the larger user base of Android devices in the market.The decision to prioritize Android user experience is primarily driven by the market landscape. Android devices have a higher market share and user base compared to iOS devices. By focusing more on Android development, ThinkCar can cater to a larger audience and meet the needs of the majority of their customers.ThinkCar is committed to providing the best possible experience for all users, regardless of their platform.
