Microsoft to end support for dedicated Cortana app on iOS and Android by 31 Jan 2020
Unlike Siri on iOS or Google Assistant for Android, Microsoft’s virtual assistant Cortana isn’t integrated into either operating system and functioned as a separate app. On Android, you could invoke Cortana faster by using Microsoft’s launcher, but Cortana is being pulled from that app as well.
The app will find a new home in the new Office365 app from Microsoft, and its functions, such as syncing to-do lists, will be taken over by dedicated apps.
On the whole, this really isn’t that much of a loss given that Cortana really isn’t that popular.
