I like the minimal design of the app, that you can use it for free even for basic features. The best way for me to watch youtube videos for language learning with dual subtitles… on iOS! But to be honest it’s still quite buggy and a lot can be done to improve user experience. So I really hope I can provide more direct feedback to Shin the developer and give my support. If the app improves enough, I will 100% suggest it to all my learning community. Forum seems dead no one replied to my questions :( Is there an email to reach you? Thanks !
