Microsoft’s Cortana apps for Android and iOS have officially reached their defunction on March 31 2021. Microsoft’s voice assistant alternative to Google Assistant and Siri will continue to function on Windows 10.
As explained in Microsoft’s Cortana support page, the mobile app is no longer supported as of Wednesday this week. Lists and reminders will no longer be available through Cortana apps on mobile. These reminders and lists can still be accessed through Cortana on Windows 10 and Microsoft’s To Do apps, available for both Android and iOS.
The shutdown was originally announced back in July of 2020 (with evidence as early as November 2019) as the company confirmed that it would shift Cortana’s focus into an AI-powered assistant for Microsoft 356 apps.
