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

Unintentionally I found https://www.f-droid.org/packages/com.github.tmo1.sms_ie

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)
