App development, short for application development, is the process of creating software applications for mobile devices, tablets, computers, or even web browsers. There are two main categories:

Mobile App Development: This focuses on building apps specifically for smartphones and tablets. These apps are designed to take advantage of the unique features of these devices, such as touchscreens, GPS, and cameras. Here are some common approaches to mobile app development:

• Native Apps: These apps are built specifically for a particular operating system, like iOS (Apple) or Android (Google). They typically offer the best performance and user experience, but require more development effort to create separate versions for different platforms.
• Hybrid Apps: These apps use a combination of web technologies (HTML, CSS, JavaScript) and native code. They can be more efficient to develop for multiple platform, but may have limitations in functionality compared to native apps.
• Web Apps: These are essentially mobile websites that are designed to look and feel like native apps. They can be accessed through a web browser on any device, but may not have all the features of native apps
