How to identify installed apps where I participate as beta tester On my Moto G (peregrine) with Android 4.4.4 I installed some apps where I joined beta tester programs long time ago (via log-in from a googlegroup etc.), and also just some weeks ago where no more group joining was necessary.

As I lost overview of the apps where I am beta tester:

How can I identify all apps where I a take part in beta testing?

(looking on my device intensively, also in GooglePlay settings and a general internet search were without success for my to find this out)
Maybe I finally found a (cumbersome?) way to find out whetre I have an app as a beta tester:

Have ideally a desktop PC with a browser and go to https://play.google.com and be sure to have logged in there with your google account.

There you can list all apps (in a kind of gallery) that are connected to your account, and even what apps are installed right now to any of your android devices that uses your google account.

Hover over one app there and you have a link for each app that leads to the indiviual item on play.google.com for each app.

For example:
https://play.google.com/store/apps/details?id=com.generalmagic.magicearth

Since summer 2015 you can take part in app beta testing (when supported by the developer) by visiting a special link for each app, like
https://play.google.com/apps/testing/com.generalmagic.magicearth

So you just need to take the first link for the "official" app,
and replace the part of the URL

/store/apps/details?id=


with

/apps/testing/


Then you can have at least three cases:


You are not allowed to take part in beta testing for this app.
You can become a beta tester for this app, when invited or it is a public beta test.
or you can see that you are already a beta tester for this app.


Anybody knows a more simple way?
