I am using the free version. I was debating upgrading but the price, given what the app does, is prohibitive. My other issue is that the free version ads are a bit ridiculous. The ads click on sometimes during an active play when I am listening to a baseball game. And today, the same ad kept repeating. It played 15-17 times in a row during one break and then 8 times 5 minutes later. Very annoying.
