DEVELOPING AN APP
There are many open source app development software available. They help us to develop an app.
While developing an app we should keep some points in mind:
The idea of developing an app should be unique.
The app we are going to develop should contain all the relevant features.
The app should be user friendly.
Let us create a mobile app with the help of a freeware software, namely, App Inventor.
App Inventor
App Inventor is a free app development tool, provided by Massachusetts Institute of Technology
(MIT). With the help of App Inventor, we can create apps for smart phones. The working of App
Inventor is similar to Scratch programming language in which we drag and drop blocks for making
an app. App Inventor has two basic views:
The Design View: This view contains all the components required to design an application.
The Block Editor View: This view is the place where we combine blocks to execute an application.
Setting up App Inventor

Inventor, follow the given steps:
