WhatsApp Messenger is one of the best, if not the best, messenger in the world. First of all, this efficient messenger app is completely for free (for the first year and then it is 0.99$ a year).
As regards its different capacities, you can send regular text messages, which also include a well-developed variety of emoticons. This includes all kinds of gestures, faces and even animals, or cars (and one of the most recent update includes ethnically conscious emoticons). Secondly, voice-messages, in which you record yourself speaking and send the message in a matter of second; and you can record many minutes without having to send it become a burden on you.
And ultimately, the phone-call feature is the one that has revolutionized the entire world. The data-packaging system is so efficient that you do not really need a very efficient connection in order to make a phone-call. Interestingly enough the sound quality is unbelievable.
One other pretty interesting feature is the possibility to make chat-groups, which is something pretty trendy nowadays in order to keep in contact with people from work or college.
Another silly, though very interesting thing to mention is the fact that WhatsApp uses internet connection (through 3G or Wi Fi) in order to function. Hence, any type of communication will cost nothing to the users.
In order to use the software people do not have the need to make any “User” as their phone number will simply be enough. And they will not be needing to add their “buddies” on the platform (as it is required in many others such as Facebook). The app will refresh its list based on you phone book, so you just need to add any contact on your phone the way you have always done.
In terms of sharing, well, you can share your location, videos and other kinds of files as well. And even, of course, if the other person is not online, they will eventually open or turn on their phone, open the app and see whatever it is you sent them.
WhatsApp has been one of the major apps that has really changed the way in which we chat, and talk on our mobile devices. It has decreased costs exponentially and facilitated communication around the world.
