Great app!

Dont know what the scam is about but it helps you know when you will get that Magical Chest, or perhaps even a Giant or silver chests. Its a tracker, and doesnt require you to put in anything. Just take note of what you get and find the pattern. Simple as cake. Cant wait for my next magical chest, still a bit far away! But as a free to play user it helps to know without spending cash!
