Does what it says

First things first: it doesnt track your chests FOR you, instead it allows you a quick and easy way to track your chests yourself.

You start by getting a few chests, and keeping an eye on when a Gold, Giant, or Magical chest appears. Based on the number of silver chests before or after one of the more rare chests, you can determine where you are in the chest award rotation.

Once youve figured that out, you simply move your tracker down as you gain more chests, and thus keep track of where you are in the rotation and when you can expect to get the rarer chests.

Another cool feature is the detailed information concerning chest contents, based on type and arena level.

Not a necessary app, but some may find it useful. Im using it because it doesnt take much time and does offer useful information.
