Miniflux. I'm incredibly happy with how simple and usable it is. I mostly use it as a PWA on my phone.
If you subscribe to some feeds that post 100+ times a day (like a major news outlet) and others that post only once every couple months or so (like many personal blogs), you'll never catch the latter because those posts are always drowned in a sea of the former. Reddit deals with this problem by weighting posts from each subreddit you subscribe to so that your frontpage contains content from as many of your subs as possible.
All I want for Christmas is for this idea to get some traction. Hoping to make the time to hack on this myself Q1 of next year.
Personally, I "solve" this problem with existing settings by excluding NPR/NYT/New Yorker from my global unread feed. They belong to a category (/news) that I can choose to visit if I want to. I find myself not visiting it that often, personally.
That being said, I have thought of implementing something like this. Maybe something that "aggregates" posts into 24 hour buckets, so they'll still show up in your global feed, but won't occupy 80% of the screen space any more.
Curious to hear your thoughts on these ideas.
Miniflux is designed to work well on a small screen with touch input. So the fact that, unlike some other options, it doesn't have a native app is not too much of a limitation.
