Requires iOS 4.2 or higher
KDCalc is for gamers who want to know how many kills they need to go up in kill/death ratio. The user inputs his total kills, total deaths, the k/d ratio he wishes to reach, his average k/d ratio, and average kills a game. KDCalc then uses these figures to calculate the games needed to reach the goal k/d ratio, kills needed to reach goal and kills without any deaths needed to reach ratio.
This is ONLY FOR IOS 4.2 AND HIGHER, reason- no decimal numpad keyboard in previous ios'
