Discord is a free app that combines the text chat aspects of Internet Relay Chat and the voice chat aspects of Skype and Teamspeak. You can chat with other users and speak to other users through it. Now, we bet you’re probably thinking if Skype and IRC exist, why was Discord created?
the game was single-handedly responsible for over 1 million people downloading Discord to play along with their friends. Because of this, the app reached the number 6th spot on the US App Store.
