Differences between mobile app and online on computer
So I wanted to learn Japanese but it's not ready (I am using Duolingo from my computer) . Yesterday though , I found out from a friend's phone , that the mobile app of Duolingo actually has Japanese courses...how come?
Normally, new courses are released in Beta test phase on the website and only after most of the problems have been ironed out are they released on the apps. However, with Japanese from English they seem to have reversed that process. Possibly because there are less problems to overcome on the app but I don't really know the reason.
