I did also start out on feddit.de but soon switched over to Lemmy.world due to too many limits when it comes to federation (e.g. general ban on nsfw instances).

Since I can still participate in all the communities on feddit.de this does work great for me

Some small addition to the last option:

If you want to browse a community from a specific instance on your home instance you have to add the ‘home’ instance.

For example your home instance (where you did register your account) is Lemmy.ml and the community you want to interact with is on Lemmy.world you would use:

Https://Lemmy.ml/c/[email protected]

In order to be able to post, reply etc

Currently it is only available on TestFlight (but was submitted for review a few days ago so I guess it will be on app store soon)

Memmy in iPad works great for me (and has an insane speed when it comes development/new features)
