1. Platform:
   • App Development focuses on creating software for specific platforms like iOS, Android, or Windows. Apps are installed directly on mobile devices and can be accessed offline.
   • Web Development involves creating websites or web applications that run on browsers and can be accessed across multiple platforms like desktops, tablets, or smartphones.
2. Languages and Frameworks:
   • App Development often uses programming languages specific to mobile platforms such as Swift (iOS), Java (Android), or Kotlin.
   • Web Development utilizes web technologies like HTML, CSS, and JavaScript with frameworks like React.js or Angular for front-end, and Node.js, Ruby, or PHP for the back-end.
3. Development Time:
   • App Development generally takes longer as you may need to create separate versions for iOS and Android or use cross-platform tools to simplify the process.
   • Web Development can be quicker, especially for single-page applications or websites that don’t require extensive functionality.
4. Cost:
   • App Development tends to be more expensive due to the need for platform-specific skills, extended development time, and app store distribution costs.
   • Web Development is usually more cost-effective since it doesn’t require platform-specific versions and doesn’t incur app store fees.
5. User Interface (UI):
   • App Development focuses on platform-specific UI, offering a highly polished and responsive experience tailored to the operating system.
   • Web Development focuses on designing responsive websites that can work seamlessly on any device, though web-based UIs may lack the fluidity of native apps.
6. Accessibility:
   • App Development allows for offline access to the app once it is downloaded, providing more flexible use.
   • Web Development requires an internet connection to access the application, although some progressive web apps (PWAs) can work offline.
7. Distribution:
   • App Development involves distribution through app stores like Google Play or the Apple App Store, which adds steps such as reviews, approval, and possible fees.
   • Web Development is accessed via URLs, making it easier to distribute to a wider audience without app store gatekeeping.
8. Updates:
   • App Development requires users to download updates from app stores, which may take longer to roll out.
   • Web Development allows for instant updates without requiring any action from the user, as the web application is hosted on a server.

3. Cross-Platform App Development to Develop Applications Faster
   • Developers with expertise in cross-platform development frameworks like Flutter or React Native can build apps for both iOS and Android simultaneously. This skill reduces development time and cost, while also ensuring consistency across platforms. It allows businesses to launch their apps to a broader audience faster and with fewer resources.
4. Back-End Computing Skills to Solve System Issues
   • Having strong back-end computing skills is critical for mobile app developers, especially when creating complex apps that require server-side logic, databases, and cloud integration. Understanding back-end frameworks, API integration, and server management helps developers troubleshoot and solve system issues efficiently. It ensures seamless communication between the app and the server, leading to a more responsive and reliable product.
5. Knowledge of App Security to Secure Portable Applications
   • As mobile apps handle sensitive user data, security is a key concern. Developers must have an in-depth understanding of app security best practices, including encryption, secure data storage, and protection against common vulnerabilities like SQL injection, XSS, and data breaches. Securing user authentication and data transmission with SSL/TLS is vital for building trust and ensuring the long-term success of the app.
