I thought this app was one of the better ones of its kind. But as it turns out, that's not the case. There has been a substantial decrease in the coin exchange rate. The apps do not report correctly when one is downloaded so you don't get credit for it. Several of them still say "Not Yet Installed" and I've had them for weeks, even months in some cases. Every email sent to support is ignored. I'm done. Off to find a better one!
