Infinity for Lemmy is on F-Droid through IzzyOnDroid's repository now!
My favorite Reddit client Infinity has a Lemmy version now, it's still heavily WIP (pre-release) but works like a charm already. A few hours ago IzzyOnDroid added it to his F-Droid repository so while it's not in the official one yet, which isn't that easy with a pre-releases app and only updates weekly, you can install and update it thought your favorite F-Droid client now! If you use F-Droid you should have Izzy's repo anyway, otherwise you did something wrong! ;)
This should be enough but if you have issues adding his repo I recommend to get Aurora Droid, it's a beautiful F-Droid client and has a list of useful third party repos you can enable with a single click!
This is highly misleading. It is, in fact, not in the F-droid repository. It's in the IzzyOnDroid repo which is a fully separate identity that happens to be a repository which speaks the F-droid API.
It has none of the stringent quality gates that F-droid so great and even allows unfree software IIRC.
It certainly reads that way to me and is easily misunderstood. I'd just stay factual and say "Infinity for Lemmy is available in the IzzyOnDroid F-Droid repository now!".
I mean, I would say I use Firefox in F-Droid too because well that's what I do but people seem to agree with you so I will change the title. Sorry for the confusion but make sure to add Izzys repo, it's a must have! ;)
