    Mobile apps are a key part of our daily lives, from games to communication tools. In this chapter,
                     you will explore how they work and how institutions like MIT contribute to creating these essential
                     tools. Let’s dive into the world of app development.

                               WHAT ARE APPS?

                     Apps are software  programs  for smartphones, tablets  or
                     computers  that  perform tasks  like  learning, gaming, chatting
                     or watching videos.  The app  is  a modern  term derived  from
                     the word application. Many apps are free, while some need to
                     be  purchased. They’re designed  to  meet  various  needs,  such
                     as  gaming,  online  classes,  music,  communication  and video
                     streaming.

                     You can download apps from stores like the Google Play Store
                     (for Android) or App Store (for iPhone).

                               FEATURES OF MOBILE APPS

                     Mobile apps have many features that make them fun, helpful and easy to use. Here are some of
                     the main features of mobile apps:

                       Easy  to  use: Apps  are simple  and user-friendly,  allowing even children to learn  quickly by
                       tapping icons.
                       Safe and secure: Verified apps protect your data and let you control settings like notifications

                       and privacy.
                       Notifications: Apps can send alerts or reminders, like when you get a message or when it’s
                       time to study. These help you stay updated.

                       Touch-friendly: Most apps are designed for touch, allowing you to tap, swipe or pinch the
                       screen without needing a mouse or keyboard.

                               TYPES OF MOBILE APPS

                     Mobile apps are divided into three types: Native Apps, Web Apps and Hybrid Apps. Let’s learn
                     about them in detail.

                     NATIVE APPS

                     A native app is software built for a specific operating system, like iOS or Android. Downloaded
                     from app stores, it runs smoothly by interacting directly with
                     the device’s hardware and can often work without the Internet.
                     For example, Instagram, Amazon, WhatsApp, etc.

                                                                                     Creating Apps with MIT App Inventor  93
