Microsoft has officially released its Cortana voice assistant tool for iPhone and Android.
The service had been available on both platforms in beta form, but the finished version can now be downloaded from the App Store and Google Play respectively.
The service offers a basic set of features across iOS and Android, allowing users to ask questions as they would with Apple's Siri, while also tracking reminders and calendar queries.
Cortana works across desktop and mobile, so if you have a Windows 10 machine you can easily start tasks on one device and finish it on the other.
The ‘Hey Cortana’ function found on Windows Phone will work on Android, with users able to wake the app by shouting the instruction at their home screen.
However, because of Apple’s more stringent controls, this aspect will not work on iPhone and is unlikely to ever be included.
Microsoft is releasing Cortana for iPhone and Android in the US. and China first. There’s no word yet on when the global rollout will begin.
