Android and Apple are two of the largest and most popular operating systems for mobile devices. Android is developed by Google and is open-source, meaning that other manufacturers can use it to develop their own products. Apple's iOS is exclusive to Apple devices and is known for its closed system, strict app store policies, and user-friendly design. Both have their own unique features, design, and user interface. The choice between the two often comes down to personal preference and the type of device someone is looking to use.
