Hey,
I recently released an app to help when choosing what to build in the popular game League of Legends.
It should be useful for anyone who’s playing LoL. Just choose your champion, runes, masteries, items etc and the app will then calculate all the stats for that build. In that way you can easily see how switching out one item for another will affect your in-game stats, for example.

I hope you’ll like it!
