Memmy has been my go-to client for the last few weeks. It feels the most like Apollo, which is what I was going for when searching for a mobile client. There was some buzz a while ago about the Lemon app, but that developer seems to have just vanished with no word on any progress. I’m not locking myself into any app for now, I still want to see who can deliver the best quality this early on, but Memmy has been winning so far.
