I’m stretching the definition of “app” here but Lemmy appears to be a progressive web app, so if you click “add to home screen” in iOS then the icon for Lemmy will open up a captive web browser that behaves like any other app.
It’s not as fast as an actual app, but it feels very similar to using one. Most apps are just react-native these days anyway.
I’m enjoying Mlem atm. It’s still missing some major features but as long as it’s not Reddit I’m happy to wait :)
