Kokoi is a stock average calculator that shows your real cost basis after every buy and sell, so you always know where a position really stands.

Most investors only know their average price after the first few buys. After you average down, sell part of a position or pay trading fees, the number in your head is usually wrong. Kokoi keeps it accurate for you.
