iOS is Apple’s mobile operating system originally known as the iPhone OS, iOS powers various Apple devices, including iPhones, iPads, iPod Touches, and Apple TV. It is renowned for its user-friendly interface, security features, and seamless integration with other Apple products and services.

iOS supports a wide range of applications, both built-in and third-party, available through the App Store. The operating system is characterised by its intuitive touchscreen controls, fluid animations, and efficient multitasking capabilities. Users interact with iOS devices using gestures such as tapping, swiping, and pinching on the touchscreen.

The iOS ecosystem is known for its closed nature, with Apple tightly controlling both the hardware and software aspects. This approach contributes to a cohesive and stable user experience but comes with restrictions on customisation and app distribution compared to other platforms such as Android.

iOS also receives regular updates, introducing new features, improvements, and security patches.
