Update: This app suddenly started playing audio after each word, even though the setting is set to off. Super annoying, this pauses the music i listen to while practising every time. The app and desktop app are good. 1 star off because there are syncing problems between the two (scores in desktop don't show up on mobile and vice versa sometimes) and also on the mobile app, the keyboard disappears sometimes when i submit the word. I have to manually access the keyboard again which is annoying.
