Web App
Definition
A software application that runs in a web browser. Unlike simple websites, web apps let users complete tasks like managing accounts, creating content, or processing data.
What is a Web App?
A web app is software that runs in your browser, accessed via URL rather than downloaded from an app store. While websites primarily display information, web apps let users do things – manage finances, edit documents, run businesses.
Google Docs, Trello, Canva, and Xero are all web apps. They're as powerful as traditional desktop software but accessible from any device with a browser.
