Some applications almost need no introduction to the general public, considering that they are so famous that it is impossible that we have not heard of them. However, it is still true that, on certain occasions, some users may not know all the functions of some programs. This is the case with WhatsApp. The most popular messenger in the world, which today we will analyze in detail.

As we were saying, WhatsApp is a free cross-platform instant messaging application for mobiles, which will allow us to keep in touch with our close people or any other person whose phone number we have in any way we need. And thanks to it, you will be able to make regular chats, voice calls, and even video calls, two of its latest features added.

To add a contact to WhatsApp, this does not happen with all messengers; you only need their phone number, and the other person has the application installed on their smartphone. As soon as you have added them to your address book, you will find that the icon appears, indicating that you can communicate with them through this service, and you will immediately see them among your messenger contacts.

What is important to remember about WhatsApp is that it is compatible with most mobile operating systems, such as Android, iOS, or Windows Phone, and allows communication between them. If you have an Android device and your best friend has an iPhone, and you want to communicate with him, it will be entirely possible to do so, something that did not happen with the first mobile messengers in history.

Then, if you can communicate regardless of your operating system, it is also fair to note that WhatsApp chats allow sending text messages and almost any content we want to share. You can send your contacts' images from the Gallery , photographs you have taken at the moment or old ones, documents, other contacts, and even links to websites . The file transfer capability of this utility is undoubtedly one of its highlights.

On the other hand, WhatsApp also has an associated platform that we can use from our computer, called WhatsApp Web, thanks to which our PC can read all conversations, answer them, send or receive files, etc. Yes, you have to keep in mind that unlike what happens with other similar applications such as Telegram, you will have to have the phone synchronized all the time.

Also, although we usually communicate privately with most of our contacts, WhatsApp offers the same functions in their groups, groups of up to dozens of people that we can create when it is essential. In these groups, you can designate one or more administrators who will have the power to add new users or remove any of the original ones if they consider it necessary.

Finally, several WhatsApp privacy options are the responsibility of the application's customers and that you can modify from your Settings, so we recommend you analyze your preferences. This way, you can decide whether to enable specific features such as information about your last connection, who sees your profile data, read confirmations, etc.

As for the WhatsApp user interface, we have to say that it has precisely the elements that we could consider fundamental for its operation, no more and no less, and that is certainly something to praise. The leading organization of the application consists of three tabs, although the main one is the first one, where you will see all the active chats you have, and moving between its menus is very easy.

The main positive points of WhatsApp have to do with the possibility of communicating with anyone else who has the application installed on their terminal, no matter what, and also the fact of being able to do so by text, call, or video call, being able to send all kinds of files. About other similar apps, its main advantage is that most people use them, so you will always have more contacts available than in the others.

As for the worst thing about WhatsApp, if it were possible to mention some aspects, we think we could stop at some unavailable features to users when they should be. Indeed, if we compare its features with those of Telegram, there is no doubt that this other messenger is more complete, although being less popular, it remains in the background.

In short, WhatsApp is the best choice you can make right now if you want to keep in touch with your friends the way you prefer, in an easy, fast, and free form, with no other need than having a phone number and a mobile or WiFi connection at your disposal.
