I’m a heavy Hacker News user and a non-native English speaker. To be honest, I often find it struggling to browse through threads and even harder to participate because English isn't my first language.
So I wrote an app called Haiker. It can automatically translate HN stories and comments. When I want to reply, I can type in my native language and translate it into English with one tap. This has helped me become much more active in discussions and discover a lot of valuable content.
I believe many other non-native hackers have the same need.
That said, it’s not exclusively for non-native speakers. It’s a beautiful HN client in its own right. Feel free to give it a try!
