The five screens and why five

A first Quiny app has five screens: the shop front, the product page, the basket, the checkout and the account. Services get the equivalents: a home, a service page, a calendar, a confirmation and an account.

Why five

Five is what a shop needs to take an order and what Apple expects an app to do. Every screen after the fifth is a change you ask for, priced like any other.

Adding a screen later

Ask for it. "Add a page for our opening hours and directions." Quiny estimates it like a new screen, builds it, and adds it to the tab bar or wherever it belongs.
