It is developed by the Open Handset Alliance led by Google.The Android operating system for smartphones was released in 2008.

Android是Google公司一個基於Linux核心的軟體平台和作業系統，目前為了iOS最強勁的競爭對手之一。Android的特點是開放原始碼，它的SDK是開放給任何開發商，所有開發商都可以隨意更改界面。例如HTC的HTC Sense、Samsung的TouchWiz等等.
iOS
iOS (formerly iPhone OS prior to June 2010) is Apple Inc.'s mobile operating system.Originally developed for the iPhone, it has since been extended to support other Apple devices such as the iPod Touch, iPad, and Apple TV. Unlike Windows CE (Mobile andPhone) and Android, Apple does not license iOS for installation on non-Apple hardware.
iOS is derived from Mac OS X, with which it shares the Darwin foundation, and is therefore a Unix operating system.
In iOS, there are four abstraction layers: the Core OS layer, the Core Services layer, the Media layer, and the Cocoa Touch layer.
iPhone、iPod Touch 和 iPad 是使用名為原名為iPhoneOS的iOS的智慧型手機作業系統，其核心與Mac OS X的核心同樣都源自於Apple Darwin。
Windows CE和Windows Mobile作業系統中間件廣泛分佈在亞洲。這2個變種改善的作業系統，是基於Windows Mobile 6 Professional（用於觸控螢幕設備）和Windows Mobile 6 Standard分別於2007年2月推出。Windows Mobile享有很大的知名度，因為進入了門檻較低的第3方國家的開發者編寫新的應用程式平台。
