Where are apps used?

An app is a piece of software. It can run on the internet, on your computer, or on your phone or other electronic device. The apps are useful for making a task easy, suppose if I want to search for technology updates there is an app for it, so I just need to go to that app and I will get all the relevant info.

The apps can be used to make detailed task easy or can play games, make documents, listen songs in just simple steps.
