Bests & Worsts Reviews from Amazon

This may be a great app but what a rip of money when they don't do a new release for kindle app but leave it here for you to buy it! After download and paying my $3.15, it then says update to new version through Google Play Store. Features don't work properly and eats your battery. Really disappointed. I would have known had I read the comments. Please take this down or update for Kindle buyers. That's not ok to take our money, when we can't use it like everyone else can.
