Google Developer Console app releases section - what is the "Internal Test" track used for?

Question

google play developer console has a near channel called "internal test". it is the last one in the list and i took a image of it below. how does it compare with alpha channel ? im not understanding its usecase ? seems your allowed 100 users.

I tried looking for documentation but i only see that it makes the app available faster. is that the prime benefit ?

Answer 1

That is correct, the Internal test track primary advantage is that APKs published to this track are available to testers within seconds, instead of up to several hours for Alpha or Beta.

Also, Internal testers can access app versions that are not otherwise available to other tracks users due to various restrictions such as device exclusions.

Finally, Internal testers do not have to pay to acquire the test version of the app, if the app is paid.

The internal test track is designed for internal testing use cases.
