What is WhatsApp and how does WhatsApp work?

WhatsApp is an application used for messaging, voice calls, and video calls. The app also supports group chat with up to 256 people.

In this article, you will learn about WhatsApp in detail and how it works.

So let’s get started!

What is WhatsApp

WhatsApp is a mobile phone app that allows you to send text messages, images, video, PDF files, voice notes and audio messages to the contacts in your on-phone address book. WhatsApp Inc. developed the application for smartphones. It’s one of the most popular messaging apps available today.

WhatsApp was founded by Brian Acton and Jan Koum in 2009. The company’s headquarters are located in Mountain View, California.

The popularity of this app has grown even more after Facebook bought it in 2014 for USD $19 billion. WhatsApp is a subsidiary of Facebook Incorporated.


Email was the standard way of sending messages to other people, but with time newer methods like SMS and now WhatsApp have taken its place. Mobile apps like WhatsApp are today an integral part of every smartphone user’s life, as they allow them to communicate exactly when and how they want it.

WhatsApp has a lot of options that enable you to customize your messages to make them look good, like adding background colors and stickers. It also lets you attach emojis, emoticons and even photos with your messages. There are many other features that the app offers like the ability to create groups for sending messages.

WhatsApp can be used on devices running Android, Windows Phone, and iPhone iOS.

What is WhatsApp used for?

WhatsApp is a free messaging and calling app that uses your phone’s data or WiFi connection. It supports end-to-end encryption for all messages, which makes WhatsApp the most secure chat app.

WhatsApp uses your phone number to keep your conversations secure, so don’t forget to add it in the app.

With WhatsApp, you can send texts, photos, videos and animated GIFs to any of your contacts on WhatsApp, even if they’re not on what’s app yet.

You can also start a new chat with anyone who has WhatsApp, and choose from a selection of free instant messaging apps or chat tools.

As soon as you download the app and verify your number, WhatsApp will automatically save your contacts so they can reply directly from their phones.

WhatsApp works on iPhone, iPad, iPod touch, and Android phones.

How does WhatsApp work?

It’s pretty simple actually. You just find the app in the App Store, download it, and when you open it up you can add friends by scanning their QR codes with your camera or typing in their phone numbers.

To chat with somebody, just tap on their name and send them a message. To see your messages, just scroll down and tap “Chats”. And that’s it!

History of WhatsApp

WhatsApp was founded in 2009, by Jan Koum and Brian Acton. It was initially released as an Android app for smartphones. It gained popularity when Apple began allowing WhatsApp to be downloaded on their iPhones in 2010.

During the first 2 years, WhatsApp had grown in popularity with clients around the globe, but it wasn’t making any money because it didn’t offer traditional advertising. The “free forever” that Koum had promised when he launched was beginning to cost the company millions of dollars every year because it didn’t offer any way to try and make money.

In 2011, the company acquired a patent for its one-to-one message encryption technology, which would later become an important part of its business model. In December of the same year, WhatsApp was acquired by Facebook for a total of U$19 billion.

Since the acquisition, WhatsApp has been pushing forward without hesitation into new territories. They have introduced features that keep their clients even more attached to their apps and they have become a secure alternative to traditional messaging services with an unparalleled reputation for privacy.

On January 13, 2017, WhatsApp released new terms of service that promised their clients the right to back up their messages.

Statistics of WhatsApp

WhatsApp reached two billion monthly active users in March 2020, up from over one billion MAU in February 2016. In February 2014, Facebook bought the service for 19 billion dollars, making it one of the most popular mobile messaging applications in the world (Source – Statista)
