One of the many strengths of the Google Play Store is that you can download apps and manage purchases right from your web browser.
When you go to download an app from Google Play on the web, clicking Install will reveal all your Android devices that can run that app. Unfortunately, by default the names can be rather wonky, like “SM-G930A” or other technical descriptions.
To give your phone or tablet a more human name, head to the Play Store and go to Settings. You’ll see a list similar to this.
