Microsoft Edge uses WebKit engine on iOS and Blink engine on Android

Microsoft today officially announced Microsoft Edge web browser for Android and iOS. While consumers will be able to enjoy the same features across different platforms, developers will have some more work to do. On Windows 10, the Edge browser is based on EdgeHTML rendering engine. For Android and iOS, Microsoft is not porting their rendering engine to the respective mobile platforms. Instead, they will make use of WebKit engine, as provided by iOS in the WKWebView control and Blink rendering engine, as provided by the Android OS in the Android WebView control.

Depending on the native rendering engines has many advantages. Microsoft Edge for iOS and Android will match the version of Safari and Chrome that is currently available for iOS and Android. But developers can identify Edge on Android and iOS by using the below user agents.
