Totally agree, atleast we can download apk somewhere outside of Play Store.

Fortunately, my primary phone is on Android 13 so don't worry, but asking here hoped that if anyone have alternative or I just simply using Miniflux web interface accessed with WebView v95-powered browser.

(Damn, I love my old phone since they have small & comfy size not like phone nowadays)

The website you mentioned is not working on my mobile firefox, I use https://armortrims.com/
