What is WhatsApp? How to use the app, tips, tricks.

 Over the last decade, there has been no shortage of instant messaging apps, as the rise of superior smartphone platforms has generated a need for more sophisticated ways to connect than old SMS text messages enabled.

Indeed, both the Apple App Store and the Google Play Store are strewn with apps that claim to be the next great thing in mobile communications. Many of services, however, failed to reach the critical mass of users required to make them useful. After all, apps designed to communicate with others are useless unless enough people use them.

While it is far from the only game in town, WhatsApp has risen to the top of the digital food chain. What began as a tiny effort to replace SMS by two former Yahoo engineers in early 2009 struck a chord, gaining a quarter-million users in its first year and expanding to 400 million by the end of 2013.

WhatsApp has been the de facto standard for cross-platform messaging worldwide since its 2014 acquisition by Facebook (now Meta), with over 5 billion installs from the Google Play Store and 2 billion active monthly users.

What is WhatsApp?

So, exactly what is WhatsApp? At its most basic, it's just a chat programme for trading messages with your friends, similar to the SMS text messaging included into almost every mobile phone.

However, the goal of WhatsApp was to replace SMS (and the limited media-capability MMS) with a new platform capable of overcoming the constraints inherent in the antiquated carrier-based messaging services. SMS was and remains to be a technology dinosaur, with 160-character restrictions and no support for anything other than pure text. MMS, its younger sibling, allows for the exchange of little amounts of data such as low-resolution photographs and sound bites, but it is effectively worthless for exchanging films and still lacks features like as read receipts and status indications.

WhatsApp was not the first app that attempted to overcome these constraints. Apple accomplished something similar with their popular iMessage platform in 2011, and Google tried multiple times with other chat apps. Nonetheless, its efforts felt rudderless and never gained traction, at least not until it recently adopted the RCS communications standard.

Nonetheless, while Apple developed a solution for its own club of iPhone, iPad, and Mac users and Google floundered, WhatsApp developed a platform-independent solution that just worked. While it is still primarily for mobile phones, it works equally well on the iPhone and Android platforms, and there are Mac and Windows versions as well as a web client that works in any current browser.

Much of WhatsApp's allure lies in its exquisite simplicity. There are no accounts to create, as with SMS/MMS and Apple's iMessage, and communications are only dependent on phone numbers. You don't need to know any nicknames or usernames to interact with your friends; all you need is a phone number. Furthermore, other than confirming your telephone number the first time you set up WhatsApp on a new device, there is nothing to log into. Your user profile consists of a name, a photo, and a 140-character "about" status. While this design necessitates the usage of a mobile phone number in order to use WhatsApp, this is kind of the purpose — and one of the likely reasons the app has grown so popular.

WhatsApp, on the other hand, extends well beyond ordinary one-on-one conversations. You can send and receive a wide range of rich media, including high-resolution images and video clips, as well as documents, audio recordings, stickers, and animated GIFs. You may also use WhatsApp to place audio and video calls to any other WhatsApp user and organise group chats with up to 1,023 of your closest friends.

How to download WhatsApp

WhatsApp is accessible for both Android and iPhone, and can be downloaded from the Google Play Store or the Apple App Store. It should be noted that WhatsApp does not provide an app optimised for Android tablets or iPad. WhatsApp requires Android 4.1 or later or iOS 12 or later, so compatibility should be straightforward.

WhatsApp Desktop apps are also available for Windows and macOS. These are available through the Microsoft Store and the Mac App Store and have comparable minimal system requirements: Windows 10.1 or later is required for Windows PCs, while macOS 10.11 (El Capitan) or later is required for Macs.

As of this writing, the Mac App Store version of WhatsApp Desktop is essentially a wrapper for WhatsApp Web. WhatsApp has a native Mac software that is presently accessible as a public beta and can be downloaded directly from its website; once it is ready for final release, it will certainly make its way to the Mac software Store.

How to get started with WhatsApp

Despite the fact that WhatsApp is available for iPhone, Android, macOS, and Windows, you'll need to start using your smartphone. Remember that WhatsApp does not have typical user accounts; you join up with your cell phone number, which is authenticated by sending an SMS message to your phone. This also implies that you must have an active cellular plan; WhatsApp cannot be installed on a mobile device that simply has Wi-Fi.

As a result, getting WhatsApp up and running is a breeze. You merely need to open the app and follow the instructions, entering your cell phone number when required. This is your WhatsApp "address" as well as your account ID. An SMS message will be sent to your phone to confirm that you are the rightful owner of the phone number in dispute.

If you're using an Android phone, WhatsApp will usually pick up this SMS message immediately and continue with the registration procedure. To register WhatsApp on an iPhone, you must manually enter the six-digit number, or tap on the autofill code above your keyboard, similar to how SMS two-factor verification works in other apps.

After you've registered your phone number, WhatsApp will walk you through a few more prompts to seek permission to access things like your contacts and images, and you'll be good to go. If you enable WhatsApp access to your contact list, which is fully optional, the app will display a list of people you know who have also registered their phone numbers to use Whatsapp. 

How to get WhatsApp on your computer

As previously said, you can install WhatsApp on your Mac or Windows PC, however this is not a stand-alone software. It is instead a companion app to WhatsApp on your iPhone or Android phone.

To use WhatsApp on a Mac or Windows PC, you must first connect your computer to WhatsApp via your phone. The first time you start WhatsApp Desktop, you'll be given instructions, as well as a QR code to scan from WhatsApp on your phone.

WhatsApp Desktop used to rely on syncing with the mobile version, which meant you couldn't send or receive messages unless your iPhone or Android phone was connected to the internet. Fortunately, WhatsApp for Windows received a substantial update last year, allowing the desktop client to communicate directly with the WhatsApp service independent of your smartphone. A new WhatsApp for Mac version with identical capabilities is presently in public beta.

You'll still need your smartphone to set up WhatsApp Desktop when using these newer full-featured versions, but once that's done, you can exchange messages with other WhatsApp users from your Mac or Windows PC, even if your phone's battery is dead or you're out of range.

WhatsApp Web, which allows you to connect to WhatsApp from any current web browser, is also still available. It's not as feature-rich as the new Windows desktop app, but it's a great alternative when you need to connect to WhatsApp from a PC at work or school where you can't install the standalone programme.

Is WhatsApp encrypted?

Throughout the service, WhatsApp employs end-to-end encryption. Whether you're simply texting, sending photographs and videos, or making a voice or video call, it'll be just you and the recipient(s). End-to-end encryption makes it impossible for anyone — including WhatsApp — to eavesdrop on your chats and conversations.

End-to-end encryption in a given conversation can be confirmed by selecting the contact name at the top of the chat and selecting Encryption. You'll be provided a QR code as well as a 60-digit number that is specific to your talk. When the other person opens the same screen on their end, this should mirror what they see.

You can also enable end-to-end encryption for the backups of your WhatsApp profile and user data, ensuring that your data remains secure and private, even when storing your device backups in iCloud or Google Drive.

Is WhatsApp safe?

WhatsApp is a safe and secure messaging medium, thanks to end-to-end encryption and confirmed phone numbers – at least for individuals you know.

WhatsApp, like any other messaging application, is not without its detractors. Because WhatsApp is so popular, there are a lot of spammers and scammers lurking about, so you should always be cautious about who you start a discussion with — and never give out sensitive information until you're certain you know who you're talking to.

Fortunately, WhatsApp has a variety of features to assist you in maintaining your privacy and dealing with unwelcome communications. You can limit the accessibility of your profile information, such as your photo and online status, to only your contacts, or no one at all, if you like.

You can also report undesired contacts if they harass you in addition to blocking them. Because everything on WhatsApp is end-to-end encrypted, reporting a user sends the latest five messages sent to you by that person so WhatsApp employees can see what's going on.

Is WhatsApp free?

WhatsApp used to operate on a subscription model, charging a small fee per year to use the service — around the equivalent of $1 per year in whatever nation a user resided in. WhatsApp, on the other hand, boldly proclaimed in 2016 that it will be free for all, and it has remained that way ever since.

WhatsApp has accomplished this without imposing advertising or other annoyances on its users, and because it is end-to-end encrypted, you are not paying for it with your privacy through data mining of your chats. While parent firm Meta is likely to have large enough pockets to fund WhatsApp, the service does make money through WhatsApp Business, a service for businesses to communicate with their customers that charges fees based on the amount of talks.
