Question about Twitter API rate limiting - GET users/show

I am interested in to get the number of followers of a user using the twitter API in my Android application.

I am reading with great interest the official twitter API documentation, however there is something that is not clear to me.

As I have understood, if I am only interested in the number of followers, just the number, I must use GET users/show in the API. This call to the server has a rate of 900 profile/15 minutes.

However, I read that this limitation is for each user TOKEN I have.

My question is:

If my application is installed on, for example, 1,000 mobiles, my app will be able to make only 900 queries to the server for 15 minutes from the 1,000 mobiles? or each mobile, which each has a different user, will be able to make 900 queries for 15 minutes.

I hope I have explained myself correctly.

Thanks and best regards.
