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 still use gReader. It's hard to find but I still keep a copy of the pro version apk (version 4.3.1_pro_beta) for Android. It just works really well and has the best UI that works the way I like it on both my phone and tablet. The latest version (which is not the one I have) was last updated April 2021. The developer was 'noinnion'.

Reeder app for Apple devices. Been using since v2 and it’s on 5. I appreciate an app that has a reasonable price for killer features, actually gives significant updates for new versions, and doesn’t have a subscription model. https://reederapp.com/

I use Flym (Android). It's not being developed anymore unfortunately but on the other hand it was left in a very good state and it's perfectly usable with lots of good features. I especially like the built-in feed search, it's very good and 9 out of 10 times it will find the feed you want and you can add it directly. Beats the hell out of poking around websites trying to find if they have a feed and where it might be.

I'm using FreshRSS along with the Readrops Android app.

Currently using Feeder(android). Layout is simple and customizable. You can also save articles on it

On my computers, I just use thunderbird. For Android, I recently discovered feeder (available in FDroid)

Tried Newsblur and Feedly. Found both ugly. Now I use the news app in my Nextcloud instance. F-Droid and the Play Store have a good app that synchronises with Nextcloud News.

Nextcloud News on desktop and android

I quickly switched to feedly after the Google reader sunset, but I mostly access feedly via Reeder on Apple products. The feedly website works well when needed though.

Pretty shocked that I'm not seeing feedbin here.

It's not free but there's a free trial. Very high quality experience.
