IOS is a mobile operating system developed by Apple that runs on Apple devices like the iPhone, iPad, and iPod Touch. It was originally called iPhone OS but was renamed with the introduction of the iPad. Unlike Android, IOS is not licensed to other hardware manufacturers. Android is an open source operating system based on the Linux kernel that was developed by Android Inc, which was later acquired by Google. It powers many smartphones and tablets from manufacturers like Samsung, LG, and Sony. The interfaces of IOS and Android differ, with IOS focusing on simplicity and fluidity while Android allows for more customization.

5. INTERFACE
Android
The interface of Android is fully customizable. It enables you to use
widgets on the home screen, change the backgrounds but it entirely
depends on the OS and UI you are using. The Nexus 4 Has Android 4.3
Jellybean with the Stock Android UI whereas the Samsung Galaxy S IV
also has Android 4.3 Jellybean with the Touch Wiz UI which differs in the
looks of the lock screen and the looks of the interface. The Multitasking
feature make it a good interface to use. However, the latest Android OS,
4.3 Jellybean is only used in the 0.4% of the Android Market Share.

no home screen. It will directly direct you to the app screen where the
apps are displayed. This reduces the customization, you can still
change the background but makes your work faster, easier & fluid.
IOS 7 made a drastic change to the entire iOS by introducing Control
Center, Multi tasking, New Notification center and many more things.
