Would this program have to come out of beta to be available on iOS and Android?
Yes, currently that is what they are doing for incubated courses. :) This may change, however.
I just checked and although it's on Android it is not available on iOS even trying what Marcin said worked for Android.
It's available on Android !
.. but at first you have to choose this course from the web. Then when you log to Mobile it will change your course to English for Polish
