Android and iOS are two of the most popular tablet operating systems. iOS is exclusive to Apple devices, while Android is used by many different tablet manufacturers. One of the main differences between the two is that iOS is known for its simplicity and user-friendly interface, while Android is known for its customizability and flexibility. iOS also has a more limited app selection than Android, but its apps tend to be of higher quality. Android tablets also tend to be more affordable than their iOS counterparts.
