Typing this 11 days after the initial question was asked and things have changed a lot since.

I've tried two apps: voyager (used to be called wefwef) and memmy.

Voyager has one problem for me on iOS 15.7: When I tap and hold an image no menu shows up, and I have no way of directly sharing an image. I can only share the link, but I don't want to do that. So if i want to share memes directly with friends and family I can't do that. I've tried to explain the problem in github but it seems like it's not a high priority and difficult for them to reproduce. I wonder if this is rooted on voyager being a web app.

Memmy on the other hand has made great progress and for me is the winner because it allows to share the images directly like I used to in apollo. They've now fixed the swipe to close gesture being too harsh, and thus I have what I need.

Here's what happens on voyager when I tap and hold an image I want to share: https://files.catbox.moe/ypz37b.mp4

Voyager is now available as a native app in the app/play store

[email protected] is pretty good

I have tested all of the IOS apps available and I like wefwef and MLEMapp the best. Both seem intuitive to use and have the handy list of subscribed communities easily available for individual scrolling.

Liftoff, at least It was the best for me at the time when sync came out. I tried everything back then, but I should do it again

Liftoff

Thunder is pretty good

Summit is pretty raw in places but it's fast and simple. The developer is putting out updates every few days and actively taking user feedback on c/summit. I'm going to stick with it.

I'm happily using fennec browser (firefox fork) on android. The web ui is fine, don't know why everyone wants an app.

Check out the community lemmyapps (not sure how to link yet), it has them all listed. I personally like Connect.

Not sure if same on iPhone but wefwef.app is great on android. Tried jerboa, connect and liftoff, this one is a pwa and it works quite well.

Thunder has the best UX out of any of the Lemmy apps I've tried so far.
