Power Apps allows you to build different types of apps based on business needs.
The main types are:
1) Canvas Apps
Canvas apps give you full control over the UI. You design the screens by dragging and placing controls. You can create mobile friendly apps with rich user experience.
2) Model-Driven Apps
These apps are built on Dataverse and focus on data and business processes rather than design.
The app layout is automatically generated based on the data model.
3) Portal Apps (Power Pages)
These apps are used to create external-facing websites. Here users outside the organization can interact with data securely.
Commonly used for customer portals, partner portals, and public forms
