Java Android app or a
Swift/Objective-C iOS app.

Xamarin.Forms is a framework that
runs on top of Xamarin.Platform
allowing a single XAML or C# UI to
be written to target several
platforms at once.

Pros
• Create UI for all platform.
• Use basic components that are available on all platform.(Button,
TextField)
• No need to learn all native UI framework.
• Fast cross platform development process.
• Simplified Maintenance.

11. Xamarin.Forms Cons
Cons
• App file size is larger.
• No recommended for UI with lots of intensive graphics.
• It's sometimes slower than accessing the native controls directly

12. Xamarin.Forms
It is best for:
• Data entry apps.
• Prototype and proofs-of-concepts.
• Apps that require little platform-specific functionality.
• Apps where code sharing is more important than custom UI.
