iMessage

iMessage is an instant messaging service developed by Apple Inc. and launched in 2011. iMessage functions exclusively on Apple platforms: macOS, iOS, iPadOS, and watchOS. Core features of iMessage, available on all supported platforms, include sending text messages, images, videos, and documents; getting delivery and read statuses; and end-to-end encryption so only the sender and recipient - no one else, including Apple itself - can read the messages. The service also allows sending location data and stickers. On iOS and iPadOS, third-party developers can extend iMessage capabilities with custom extensions, an example being quick sharing of recently played songs. Launched on iOS in 2011, iMessage arrived on macOS in 2012. In 2020, Apple announced an entirely redesigned version of the macOS Messages app which adds some of the features previously unavailable on the Mac, including location sharing and message effects.
