Google recently put Chrome OS into Windows 8 as a Metro app. Now, an announcement on the Chromium blog tells us that they are bringing Chrome apps to iOS and Android.

Today we’re expanding their reach to mobile platforms with an early developer preview of a toolchain based on Apache Cordova, an open-source mobile development framework for building native mobile apps using HTML, CSS and JavaScript. 

The toolchain wraps your Chrome App with a native application shell and enables you to distribute your app via Google Play and the Apple App Store. We provide a simple developer workflow for packaging a Chrome App natively for mobile platforms. You can run your Chrome App on a device or emulator using the command-line or an IDE. Alternatively, you can use the Chrome Apps Developer Tool to run your app on an Android device without the need to install an IDE or the mobile platform’s SDK. 

In simple words, you can write an app for Chrome using HTML, CSS and Javascript, and with a tiny bit of extra work, make them work on Android and iOS platforms as well.

Exciting times for Chrome app developers!
