Big Hunter is a free to play game from KAKAROD INTERACTIVE that has in-app purchases at $1.99 per item.

You're a might hunter for your tribe and your goal is to feed your tribe by killing mammoths with nothing but a spear. Each day you'll be greeted with unique challenges. And you have limited spears to kill your prey, so you'll need to find the mammoth's weak spot or string together combos to defeat him.
