There are many Android File Libraries and user review sites. I found it one of the other File Library Web Sites that originally reference the Google Play store Beta download for the app but also had a mirror for many Apps including that one. It was after the company had released and then closed the public Beta, after they had enough testers. I got it in between the time they had just taken down the main page on the Google Store front and just before the secondary site took down the mirror.
