An Amazon Prime Video app has just been released in the Microsoft Store for Windows 10 computers. You may think it’s unnecessary to have a dedicated app, since you can access all the same content through a browser, but the app comes with the unique ability to download videos for offline viewing. Like Amazon’s mobile apps, you can select from video quality settings of Good, Better, and Best when downloading content. One hour of video at the highest setting, which maxes out at 1080p, will use around 2.4 GB of storage space. The app is free, but you’ll need a Prime membership to access movies and shows.
