Can't try it
Requires a https connection, and I don't want to set up a reverse proxy just for this app. I was trying to replace another app that doesn't have an issue here, but isn't that well maintained.
App Works Great
Overall, a great app does exactly what you wanted to do. For those of you that are having a hard time logging in, you have to use an API password and not your normal one.
Fails to Login
Unable to sync with my server. I confirmed multiple times that my FreshRSS instance is accessible at the provided url and that I can sign in with my username and password. It fails to connect in this app, works fine on my server’s web page.
