Bests & Worsts Reviews from Amazon

I picked this app for 2 reasons. My Granddaughter loves to play Angry birds. The App was free so - why not. I was playing it to see how it worked. Next thing, I could up-grade for a price. Then I could get more points for a price. I could just see my Granddaughter buying every upgrade that came along - and I would be broke. If there is a program for angry birds that does not ask for more money at each turn I'll look into it. for now, I have deleted this program from my Kindle Fire.
