E2:If this is somehow the first post you found in your journey, this master list of apps and how to download them will help more than this post:https://lemmy.world/post/907413 Also the test flight links in the post worked.
There are no lemmy-related apps in the iPhone store. All the websites for the apps lead to placeholder websites or websites that don’t work.
E: Thank you all for your help. The websites only work when accessed via phone. Still no test flight codes yet. I’m not going to delete this because I know others are probably going to have the same struggle and question.
For wefwef specifically, it’s a PWA, so open this on Safari and follow instructions there: https://wefwef.app/settings/install
For other apps, they’re mostly still in beta and you need a TestFlight invite link. Search for the posts here and they’ll probably have the link
Memmy should be on the Appstore in a few hours!
