Manage different devices on one place I would like to manage different Android devices on one place. It means I would like to see information about these devices on a single account. Mainly I would like to get a list of installed applications, latest geographical position.
There are a few ways to do what you're looking for.

One option is to use a parental control app that lets you see the location, browsing history, apps downloads, sms activities, etc.
One such app is called qustodio. You can find many similar ones online.

This method will require you to have the Google account password for the device in question. (This method is only ideal if all devices are using the same Google account)


open play.Google.Com in your browser in desktop view and after signing in, go to the menu>apps, and you'll see a drop down list. In the list select the device for which you want to see installed apps. Scroll through the list to see the apps that were installed
to see the location of the device, you can use Google's find my device option. After logging in you'll see the location of the phone. (Note: sometimes the phone will get a notification that the device was located using this option)
