Microsoft officially released Cortana for Android and iOS. The Windows voice assistant now can be downloaded in top competing mobile platforms, but currently works only in selected countries.

Cortana for Windows is the alternative to Siri and Google Now, but following to its new strategy Microsoft opened its applications and services for all platforms.

So far, Cortana is available for Android and iOS through beta testing among a closed group of users, but today the application made its official debut on Google Play and App Store.

Of course, users will get quite a worthy alternative to its Google Now and Siri as these services are deeply integrated each in its platform, but Microsoft promises some useful extras.
