Free Instant Messaging Apps
Instant Messaging Service (IMS) or Instant Messenger (IM) is a client program for real-time chatting over the Internet. To use such services, you only need a device (smartphone, tablet or PC) and Internet connection.

In the early days of instant messaging, people used two different programs to communicate. On the one hand, there was ICQ, a program developed by the Israeli company Mirabilis. It was one of the first to allow chatting with friends, family, or strangers. ICQ was acquired by AOL in 1998. On the other hand, there was Yahoo! Messenger, which was launched in 1998. This program allowed people to communicate with each other, share photos, and make video calls.

Nowadays, instant messaging is one of the most popular means of communication. Especially with an iOS app builder and other tools, it has become way more easier to develop and deploy custom communication apps for instant and more effective communication. WhatsApp, Facebook Messenger, and WeChat are some of the most widely used programs.

Consumer apps vs Business apps

The culture of communication is changing and adjusting to the standards of time. Instant messengers have become an integral part of our lives: they are now popular tools for everyday and business communication. We text, record voice messages, and resolve issues in group chats or during video meetings.

However, with the advent of app builder tools, businesses can now design tailored messaging platforms specific to their needs. To solve the work tasks, we often require not only a separate messaging service but a full-fledged platform for remote work with advanced collaboration features that can provide reliable communication and effective team management. This is why the standard functionality of popular messengers such as WhatsApp or Facebook Messenger may not be enough for large companies. Additionally, you can also have an advanced help desk ticketing system to manage all your messages or emails in one place automatically.
