It seems that many popular mobile apps nowadays have their own design language. I like uniformity between my apps so I greatly respect when an app developer takes the care to design their app to follow their OS Human Interface Guidelines. For example, apps like Apollo (and wefwef/Voyager for Lemmy) rose to popularity partly due to looking and feeling like native iOS app
The best was defintely Apollo. Memmy seems to be trying to push the native iOS UI forward, but it’s early days for that app.
