Mobile app development encompasses creating software applications for mobile devices, typically iOS and Android platforms.

Native vs. Cross-platform:

• Native Apps: Built specifically for iOS (Swift) or Android (Kotlin/Java), offering the best performance but higher development costs.
• Cross-platform: Using frameworks like React Native or Flutter to write code once and deploy it on multiple platforms, reducing development time.

Key Considerations:

• UI/UX Design: Must be tailored for smaller screens and touch interfaces.
• Performance Optimization: Focus on responsiveness and efficient use of resources (battery, CPU).

With the growing use of AI, machine learning, and AR/VR, mobile apps are becoming smarter and more immersive.
