## What is Ruby Stone?

Pricing too low is one of the most common and costly mistakes small businesses and freelancers make, and it usually happens not from carelessness but from genuine uncertainty about what the real number should be. This app removes that uncertainty by giving you a fast, reliable way to calculate profit margins, markups, and break-even points from actual cost data. Enter the cost, decide what margin you need, and the app tells you the price.
