What is the Difference Between Web App & Mobile App?

The key difference between web apps and mobile apps is their functionality and accessibility. A web app is executed in a web browser and needs an internet connection, whereas a mobile app is an individual application meant for a specific mobile device and can be used online as well as offline.

Web applications are accessed through URLs, while mobile applications must be downloaded from application stores. The main difference is that mobile applications provide deeper integration with device functionality, like camera, GPS, and push, while web applications are more platform-agnostic and can be viewed on multiple devices.

What Is a Web Application?

A web application is a computer program which is hosted on a web server instead of running on a local device. The users communicate with web applications by using a web browser to interact with the same over the internet.

Web apps are specifically tailored to perform dedicated tasks such as data management, sending email, or even advanced operations, but without needing software to download and install. Examples of web applications are online banking sites, social networking websites, and collaborative platforms such as Google Docs.

How Does a Web Application Work?

Web applications use client-server architecture. The client is the web browser of the user, and the server is where the web application is hosted and executes requests. When a user makes a request, like clicking a link or filling out a form, the client sends it to the server, which processes the information and returns the correct response, usually in the form of HTML, CSS, and JavaScript.

Web applications also depend on backend databases to store and dynamically retrieve data. One of the fundamental features of web apps is that they need to be connected to the internet to operate, and updates are maintained server-side, meaning users see the latest version at all times.
