Any reddit app which allows only some subreddits to browse and no other noise?

I am sorry that this not the right subreddit to ask this question but I am couldn't found any relevant subreddit.

I don't want r/all or popular or any subreddit suggestions or even site search.

I just want to browse say 4 subreddits which are of my interest. Is there any app which can do this or offer such feature?

I am using Boost but I don't see this feature in the app. I was hoping that the community knows any other App.
