is Czech available for Duo Android app?

I learn Polish on my phone. As soon as Czech was added to the list of languages, I wanted to add it to my languages on my phone but I don't see it on the list there. Is it available for Android yet?

It used to be that the courses started beta on the web only, and when the number of user reports per 100 users dropped below 7.0/100 per day for 21 days in a row, they would come out on the mobile apps shortly after that. And when that statistic remained below 3.0/100 for 21 days in a row, beta would end. That's what it used to be. These days, I don't have much of a clue. The statistics for this course that were displayed to me at least temporarily show us below 7.0/100 since about September 9. But not all days are ever shown. The chart that is visible to me only retained the data back to September 14 and shows only 10 days between that date and September 27. Yeah, many days are missing. The highest of the 10 values is 3.25/100. The number of active users is still so small that the scatter is massive.


No, it will probably come to mobile around the time it graduates from beta, but some courses have come before that.


The courses are usually released on the web first, and once they are more stable, they are released on the apps. (Notable exceptions being Japanese and Korean, which went to the apps first.)
