Mlem is just one person, from my understanding. Memmy isn’t a big group, but it is a group.
Memmy - An iOS client for Lemmy
Mlem was one person, but now it's a team. The original person left.
Mlem is also a group, but the founder left recently which has likely thrown them for a bit.
Do you have any more details on this (or know where I can find more). I'm currently trying to decide which Lemmy app to use, and would be interested in reading more about Mlem's history.
I don’t I’m afraid other than what I saw posted in the mlemapp community. There was also some recent shenanigans over that which again seems to have been resolved and they posted an update to the app recently.
Personally, I’m sticking with l memmy now, as keeping too many on the go was just a pain. The memmy community is great, responsive, and I’ve got a couple of PRs in now.
I've been keeping all the various Lemmy apps in a folder on my home screen and switching between them to get a feel for them all. So far, I haven't found any that are perfect (nor would I expect to this early on), but Memmy is definitely up there.
