Recently my iPod displayed a message telling me that I had purchased an app on my computer and that I could turn on automatic app downloads on my iOS device. Here are the steps to do so:
- Go to Home screen -> Settings -> Store (you may have to scroll down)
- Wait for the “Automatic Downloads” listing to display (you may have to login with your Apple ID if you haven’t already)
- Toggle the “Apps” option to “ON”
Now you should be all set!
