I've been trying to find an app that works with my self-hosted FreshRSS instance. Supposedly Readrops supports freshrss, but since it's self-hosted, I am having issues getting the self-signed SSL cert working. Readrops demands to connect with SSL, and despite adding the cert to the Android system trust list, Readrops still throws exceptions when it tries to validate the certificate. Until I can figure that out, I just use FreshRSS web interface, it's acceptable.
