Lesson 2: Types of Mobile Apps

Mobile applications are grouped into different types based on how they are built and how they run on devices.

1. Native Mobile Apps

Built for one platform only
Android → Java / Kotlin
iOS → Swift

2. Web Apps

Run in a browser
No installation needed
Limited device access

3. Cross-Platform Apps (Flutter)

One codebase
Runs on Android & iOS
Fast development

Flutter Example Code


import 'package:flutter/material.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Types of Mobile Apps'),
        ),
        body: Center(
          child: Text('Flutter is Cross-Platform'),
        ),
      ),
    );
  }
}
