Confused with rate limits on apps


Hello Im coding an app using rest api v1.1 making user oauth and grant access to the app to analyze their tweets.Generating personal infographic data.
I still havent understand rate limits,are this limits individuals per user or global per app?


The user-based limits when using a user-based access token are unique to the application-user combination for you. There is also a second pool that is your app-only auth rate limit pool which is intrinsic only to your application.


So, just to clarify, if I want to use app-only auth to access one user’s public Twitter list (using GET list/statuses) on an iOS app with 200 unique users, only 180 of them could make the above request in a 15 minute time period (the rate limit page says 180 requests per 15 minute window)? Thanks.
