I have just released this “saucy” app:
https://play.google.com/store/apps/details?id=com.fulltilt.fingerstripper
It has interstitials by VSERV.
It also has in-app purchasing.
I know the in-app purchasing “shop” is rather clunky, but if the downloads
start to look good I will go to the trouble of making it all look more professional.
I’m very happy to hear peoples comments on the app itself and/or my marketing
and/or my monetization strategy.
