I believe they may be out of slots for TestFlight but it sounds like they hope to release a version for everyone soon.

Here you go. Be aware that it’s in development still and is sorta rough (eg does not have a search feature, etc). https://github.com/gkasdorf/memmy/discussions/13

Here’s the TestFlight invite!

You’ll have TestFlight since you’re testing Mlem but download it if you don’t.

This is the TestFlight link for memmy.
