Use any pronouns you prefer to refer to me, unless you’re gonna be weird about it.
Droidify is a client of F-Droid, I wouldn’t say either is better, it’s preference.
I imagine they just want to recommend something already on F-Droid, and, I also imagine the IronFox people will start releasing on F-Droid directly soon vs having a added repo. But, adding the repo is not hard.
I would just type “photo editor” into F-Droid and browse, nothing on F-Droid will have ads. If you don’t have F-Droid installed follow this.
