App pricing is not determined by the number of screens alone. The real cost comes from the product logic, integrations, user roles, backend services and the amount of testing required.
What matters most
A simple information app may need only a few screens and can be delivered quickly. A marketplace, booking platform or delivery app requires accounts, APIs, notifications, payments, dashboards and operational workflows.
At Code24 we normally start with a discovery conversation, define the MVP, then separate must-have features from phase-two improvements. This gives a business a realistic launch budget without paying for features it does not need on day one.
