In Google play it says installed next to an app. How do I know which device it's installed on?

It looks like you have a good answer already, but here's a link to the Google Play help page in case you need it later:

Go to Play using a browser, then in the sidebar on the left of the screen, click the “Apps” bar.

Once you are on the Apps screen, click “My Apps” to go to the “My Android Apps” page. At the top of this page you should see an “All Apps” drop-down menu. Click on “All Apps” and you should see a list of your registered devices. Just click on the device you want to check, and you should see all the apps installed on it.
