This article explains all the options for adding Android apps to Windows 11. It includes three methods, two of which offer an app store similar to the one on an Android device.

It may sound confusing, but in the Microsoft Store there is an app called Amazon Appstore. This gives you access to Amazon's app library in Windows 11.

Open the Amazon Appstore download page and select the Download from Store app.

If you see this prompt, select Open Microsoft Store.
