Mlem does have search. Tap the middle of the top bar, where it says “Subscribed” or “All”. Then tap “Communities…”

I’m surprised people can’t discover this, considering it’s the same workflow as Apollo.

Thank you for the point about the length of development. I essentially started Mlem a year a half ago as my very first iOS project to take my mind off the pain from a major surgery I had the the time, then it sat abandoned until I revived it just a little over month ago. So the total dev time on Mlem is only around a month and a half. It’s still a little baby 😊
