Norwegian is now on iOS!
Oh. That's cool. I started Esperanto, but dropped it because it was not in the app. Guess I'll take it when I finish with Swedish :-)
Soon... hopefully... I expect it in a few days! (I have no idea how long the other courses took from iOS to Android, but still...)
Ukrainian is currently receiving a higher number of reports per 100 users than Norwegian or Esperanto. I highly doubt the Duo team just forgot about Ukrainian.
