I've been using Mlem via TestFlight. It's solid. My only gripe is minor. I see a large amount of duplicate posts across different Lemmy instances. For example, Beehaw's c/technology and Lemmy.world's c/tech often have the same content posted. My guess is it's the nature of federated content. It'd be very impressive if you find a solution to consolidate duplicate posts from Lemmy instances.
Mlem is Ok, but still lacks way too man QOL features. I found Memmy as well, which is a bit newer, but also seems to be way more polished already, and the dev does updates almost daily. Already has listed communities, search, a working feed that doesn’t duplicate, and blurred NSFW.
Same, I’ve switched to Memmy almost entirely. Seems like a very active and driven dev. Lots of features and very polished in like 5 days or something crazy.
It does this already. When there are multiple posts with the same link they are grouped together and you can choose which one to enter when you navigate to the comments. Still experimenting with it
Group by links and then merge comment sections while showing which instance they are coming from with the usernames would make the whole fediverse feel really cohesive.
