Hey guys!
I'm a Catholic dev, and I realized that there wasn't an open-source Breviary app.
To fix this, I quickly threw together
OpenBreviary, an open-source way to access iBreviary's web client.
I also started up an Fdroid repo for this program at
https://github.com/2br-2b/Fdroid-repo/. If any of y'all have apps I can add, let me know! If there's enough interest, we could also create a Catholic Fdroid repo, as I may add a few other apps I end up programming there.
