No, someone else noted that the screenshots on F-Droid also included Droidify, idk why, but they are completely different apps.
The README also says that neostore is a "direct adaption of foxy-droid" so maybe it is a fork of foxy droid?
I've used both droidify and neostore, but I stuck with neostore as it felt more "finished".
Ah thanks, didn't know this.
