How to check if a chrome app is installed in a different chrome app?

I am wondering how I could check if a app is installed in chrome from a different chrome app. For example I have made app1 and app2 now I want to know if the user has app1 installed when he/she opens app2. Is this possible by some chrome api or is this not possible?

If I can not check if the user installed app1 then is their a work around of some sort?

I do have access to the chrome webstore if that matters.

What I want to do is provide some loyalty perks to those who install my other apps.

Since you wrote both apps, it's pretty simple by using External Messaging:

In app1 background script:

var app2id = "abcdefghijklmnoabcdefhijklmnoab2";
chrome.runtime.onMessageExternal.addListener(
  // This should fire even if the app is not running, as long as it is
  //   included in the event page (background script)
  function(request, sender, sendResponse) {
    if(sender.id == app2id && request.areYouThere) sendResponse(true);
  }
);

Somewhere in app2:

var app1id = "abcdefghijklmnoabcdefhijklmnoab1";
chrome.runtime.sendMessage(app1id, {areYouThere: true},
  function(response) {
    if(response) {
      // Installed and responded
    } else {
      // Could not connect; not installed
    }
  }
);
