An instant messaging application is a web, mobile, or desktop application that allows users to communicate with each other in real time. IM apps typically include features for sending messages and files, scheduling messages to be sent at a later time, and creating private groups.

Instant messaging apps are very similar to group chat apps, conference calling apps, and video conferencing apps. Some popular instant messaging applications include Facebook Messenger, WhatsApp, WeChat, Viber, and Skype.

An instant messaging app's growth strategies are similar to those of a dating app, but with two notable differences. First, the pool of potential users is much larger for an IM app because the audience includes anyone who owns a smartphone. Second, instant messaging apps can grow their user base by offering unlimited use for free, or by offering free credits or coins that can be used to pay for in-app purchases.

Instant messaging apps can face legal and reputational risks associated with the distribution of copyright content, the distribution of sensitive personal information, and the distribution of harmful code. It is recommended that instant messaging apps take strong measures to reduce the distribution of copyrighted material (including by leveraging APIs from popular content providers like SoundCloud) and that they provide mechanisms for users to report harassment or abusive content.
