Amazon today launched an Alexa app for Windows 10 PCs on the Microsoft Store. The voice application allows PC owners to speak to Alexa to set reminders, timers, alarms; create lists and to-dos; track their calendar appointments; get news, weather and other information; play music; listen to podcasts and audiobooks; control the smart home, and more.

The app is another way that Alexa is being unhitched from Echo speakers and other devices that generally stay in the home. Similar to the Alexa app for mobile devices, the Windows 10 app means you can use Alexa when you’re traveling for access to content and information, as well as to do things like lock your doors or check your security cameras, for example.
