Mobile App Architecture Basics: Screens, Logic, and Data
Mobile app architecture describes how an app’s parts share responsibilities. A screen presents information, app rules determine what actions mean, and data components provide or retain information. Architecture explains how those parts work together.

A booking might appear on a calendar and in an upcoming-appointments list. Both views refer to the same reservation. Separating its information from either screen helps explain how the app can present a consistent status.
Organization is a different question from hosting
A backend describes services outside the device. Architecture also concerns how code inside the app is organized, even when the information stays local. Android’s architecture guidance distinguishes UI and data layers.
Responsibilities shape how changes spread
Architecture concerns how an app's parts fit together. Displaying a total, calculating it, and retrieving its source records are related responsibilities with different reasons to change. Their organisation affects how easy it is to understand the effect of an update.
A small app does not need every pattern used by a large system. The useful question is whether responsibilities and information flow are clear for the current product. That connects architecture to ordinary maintenance decisions, rather than treating it only as a diagram of folders.
