About this app
This application is an educational business simulation tool designed to help users understand how pricing, costs, and sales volume influence profitability. The experience focuses on simplifying Cost–Volume–Profit (CVP) concepts through interactive scenario modelling. Users can experiment with different business assumptions and instantly see how changes affect revenue, profit, contribution margin, and break-even points. All calculations are based solely on values entered by the user, allowing individuals to explore hypothetical situations in a structured and visual way. The app provides a simple environment where learners, students, and professionals can model business decisions without using complex spreadsheets. By adjusting variables such as price per unit, variable cost, fixed cost, and expected sales volume, users can observe how financial outcomes change in real time. Visual charts…

What you can learn from Choz Lab
Every shipping app on the App Store has gone through the same decisions you're working through right now: which screenshot goes first, what caption sits over it, which device frame to show, what color the background should be.
