WhatsApp Messenger

Chat apps

Online chat apps are among the most important apps on smartphones, due to their great importance and usefulness in the process of social communication between users. They are used to communicate with friends and family anywhere in the world, and they are free and do not need registration for most of them.

Because of the large number of chat apps, it has become difficult for the user to choose an appropriate app, as all apps compete with each other to provide the best services to gain user satisfaction, and tech companies are racing to issue more social networking apps in the hope of achieving success and increasing the number of their users.

Chat Apps and SMS

Chat apps are replacing SMS messages that are less used, as telecom companies deduct an amount from your balance when you use SMS messages. While chat apps are free and require an internet connection only, users use chat apps to communicate with others in most cases. 

WhatsApp

WhatsAppis one of the most important chat apps present on the Internet, and it is the most popular app among users, with the number of its users reaching more than one billion users. This is not surprising given the great and continuous effort that is being made to develop the WhatsAppchat service. 

The beginning

The beginning of WhatsAppwas in 2009 when Jan Koum launched an initial application that replaces SMS and MMS messages. The phone number was relied upon as the only way to register to the app, without the need to enter an email or additional information, which helped in the spread of the app significantly at that time. 

Rising popularity

There are several reasons that helped the spread of WhatsAppwidely among users, such as providing the app for all phone systems and supporting a very large number of languages around the world. Also, the app does not contain any ads at all, and the fact that it received sums for investments helped in the development of the service very significantly and its resounding success.

An amazing success

Over the years, WhatsAppachieved great success, and the number of users increased very significantly, it reached one billion users in the year 2016, and it got one million new users daily, and millions of messages and photos are shared on a daily basis between users, and 100 million calls are made through the app.

Facebook's acquisition of WhatsApp

With the spread of WhatsAppamong users, it became a source of threat to the social networking giant Facebook, especially since WhatsAppis more private and easier to use, so Facebook had to make a move, which was actually done in 2014 when it purchased WhatsAppservice in a huge deal totaling $19 billion.

Messenger shortcomings

• The photo cannot be shared in the original size
  
  When you share photos in private chat or groups, WhatsAppautomatically reduces the size of the photo, and you will notice that the details of the sent photo are less clear than the photo on the phone before sending, and you cannot share high-quality photos as they are.
• Does not support live stickers in the camera
  
  WhatsAppcamera does not have the capabilities of the cameras of other chat apps such as Snapchat, Messenger, and others. You will not find the feature of live stickers that recognize the face and transform it into many fun forms that can be shared with friends, perhaps in the future, we will see this beautiful feature in the app.
• Restrict the number of group members
  
  It is one of the restrictions imposed on users on WhatsAppwith regard to groups, as the app allows only 256 members in the group, and no new member can be added when the number is complete, unlike other apps such as Telegram, which allows thousands of members to join the group.
• Does not support group calls
  
  Group call is a nice feature for friends or family, but on WhatsApp, you cannot make calls with more than one person, and we expect this feature to be added in the upcoming updates to the app.
• It does not support automatic-deleting messages
  
  WhatsAppdoes not support the automatic-deleting feature of messages, which is a message that is sent to the other party that automatically deletes itself after reading it for a period of time that you specify, and it is a popular feature on many chat apps such as Messenger, for example.
