First let me say - SCREW YOU GOOGLE FOR SHUTTING DOWN GOOGLE READER. I WILL NEVER FORGIVE AND I WILL NEVER FORGET.
I moved over to NewsBlur for my aggregator, and I’ve been really happy with it. It’s a small team, and the dev is very responsive to issues and suggestions. Reading articles online is quick because it uses many of the same keyboard shortcuts that GReader used.
On my iPhone I rotate between Fiery Feeds, Unread, and NewsBlur’s app to read my articles on mobile.
I use Pluma on Android since it’s the only one on Android I’ve found thatvhas an option to filter out articles by keywords
I use the news-app of my Nextcloud to aggregate and manage the feeds. To actually read them I connect the news-app with Nextcloud.
On my computers, I just use thunderbird. For Android, I recently discovered feeder (available in FDroid)
