Almost ten years ago, Apple unveiled the new iMessage app at WWDC 2011; the app would replace SMS texting on iPhone with something much better. iMessage works over cellular and Wi-Fi, adding a richer instant messaging experience over an internet connection. The app also provided end-to-end encryption, the kind of strong privacy protection other chat apps lacked. Apple brought the app to iPhone, iPad, and Watch in the following years, but it never developed iMessage versions for competing platforms.
