Amazon Reader and iReader are two different e-reading devices. Amazon Reader is launched by Amazon, with a powerful e-book library and Amazon's ecosystem support. It provides a wide range of book selections and cloud synchronization functions. iReader is developed by China's iReader Technology and is mainly aimed at the Chinese market. It also has its own e-book library and ecosystem, but the book selection may be less compared to Amazon. In addition, Amazon Reader usually has more features and technological innovations, such as high-resolution screens, backlights, and anti-glare. iReader pays more attention to localized services and user experience.
