iOS is a mobile operating system created by Apple that originally launched on the iPhone in 2007. It has since expanded to support iPod touch, iPad, and Apple TV devices. The operating system is updated annually and has added many new features over time, such as app store functionality, Siri voice assistant, iCloud services, and more. Applications available on iOS include native apps designed specifically for the platform, hybrid apps that are web-based but wrapped in a native container, and web apps that run within a mobile browser. Popular app categories include games, social media, productivity, entertainment, and more.

5. ● Native Apps
Native apps are installed through an application store (such as
Google Play or Apple's App Store).They are developed
specifically for one platform,and can take full advantage of all
the device features — they can use the camera,the GPS,the
accelerometer,the compass,the list of contacts,and so on

6. ● Hybrid Apps
Hybrid applications are web applications (or web pages) in the
native browser, such as UIWebView in iOS and WebView in
Android (not Safari or Chrome). Hybrid apps are developed
using HTML, CSS and Javascript, and then wrapped in a native
application using platforms like Cordova. This allows you to use
any web-native framework you want, and there are plenty of
these.

7. ● Web Apps
If you’ve ever seen the ‘mobile version’ of a site, that’s what
we’re talking about. An “app” like this loads within a mobile
browser, like Safari or Chrome, like every other website. Your
audience doesn’t have to install a web app. They don’t need to
have available space on their devices.Web apps are sometimes
designed to look and behave like apps and are in general ideal
when the purpose is simply to make content or functionality
available on mobile
