Complicated but very useful. – LegendSmith - for League of Legends Review

I think this app is definitely a "must have" for serious league players because it gives you accurate statistics and allows for knowledge of your stats before the game even starts. It allows you to calculate your dps and burst well with the exception of items such as sated devourer and champion abilities such as shyvana's q passive cooldown. There is also a glitch with tenacity calculation that says that you have 8000%tenacity with mercs alone.(I wish Rito) overall I like this app because it gives you so much. It may be a bit overwhelming at times but it is really great to have for planning out builds.
