Damus iOS supports Korean. We have one Korean translator so far and the app is currently 80% translated (112 strings untranslated) in Korean. If you’re interested in joining the translations team, go here:

We also have a group chat if you want to join that. 

 Damus is doing a great job at internationalization and localization.  

 mostly thanks to @tyiu 😅 

 It’s a team effort. We’d be nowhere without the translators. 🤝 

 💯 

 thanks! I'll check for this

how about Iris??
