Study Notes

App Development

Apps are software programs primarily designed for handheld devices like smartphones and tablets.
Apps help users perform personal and professional tasks efficiently.
The word "app" is derived from "application."
Millions of apps are available for mobile devices, most free to download from app stores.
Popular app stores include Google Play Store, Apple App Store, and Microsoft Store.
Desktop apps run on computers or laptops, are specific to operating systems (e.g., Windows), and examples include Paint, Notepad, and Word.
Mobile apps (also known as mobile apps) are designed for smartphones and tablets and are installed and run directly on the device; examples include Snapchat, WhatsApp, and Facebook Messenger.
Web apps are web applications similar to native apps but require an internet connection to operate.
Some instances of web apps include OLX, Flipkart, and Pinterest.
A hybrid app combines native and web app features; it requires installation before use and can run on various platforms. Examples of hybrid apps are Instagram, Gmail, and X.
