Thought I'd share my data of the growth on the Google Play Store. Screenshot on the left is from yesterday (18/06/19) and screenshot on the right is from 10/09/18. Download figures difficult to determine as they are heavily rounded, but still an increase from 500K to 1M. Perhaps more indicative are the ratings figures, increasing approximatly three fold; 5K to 15K. Looks good for the $50 club.
