Vger.app - progressive webapp. Installs and runs as a real native thing. Give it a go. I chose that one as a stopgap thing before Sync arrives and it is hard to stop using it now. Just now I found Infinity (https://codeberg.org/Bazsalanszky/Infinity-For-Lemmy/releases). Absolutely brilliant android native app. What to choooooose? I dont know.
You have to download TestFlight which is apples beta testing app. I recommend Memmy for an app that’s on the App Store. Looks and feels a lot like Apollo did
I don’t like memmy, the interface feels very non native to iOS. Mlem feels much more like Apollo imo, and just much more like a good iOS app in general. Also Mlem was recently taken out of beta and is now in the App Store!
