Good tracker if you know how to use it.

Lots of the bad reviews are because people think it auto tracks where you are in the chest rotation you are. This is not the case.

I suggest maybe putting in a tutorial if this gets updated.

Also it would be awesome if it were to explain the amount of hours needed until you reach your next chest.

Other than that, a really good clash royale companion.
