Shark Whisperer - Audio RNG For Live Poker (Android Testers Needed)

Hi everyone,
I am not a live player, but I started using an RNG for my online play since solvers became a thing. Before that, I used card suits for balance, but I think an RNG is just more practical (and less exploitable).
I've seen comments and heard stuff about how live players do it: patterns on chips, looking at tournament clocks, or Doug Polk shuffling hole cards and dealing one out.
Anyway, I thought of better ways to do it, all visual-based, until I came up with the (either stupid or brilliant) idea to do this with audio. So I created this simple app. Google now requires new developers to have 12 or more closed testers test their app for 14 days straight.
So, I'd like to present my idea here, get feedback, and hopefully find enough testers so my app can finally get published.
Anyone interested? If you complete the 14 days of testing (you just have to stay enrolled), you will get a bonus code for the premium version.
If not, I'd still appreciate your feedback on the idea, because the only testing so far has been my own in a live setting (I found it works for me).
Thank you!
