iMessage is an instant messaging service developed by Apple and launched on October 12, 2011. iMessage functions exclusively on Apple platforms – including iOS, iPadOS, macOS, watchOS, and visionOS. iMessage uses the Messages app client.
Core features of iMessage include sending text messages, images, videos, and documents; getting delivery and read statuses (read receipts); and end-to-end encryption so only the sender and recipient 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.
iMessage was introduced with iOS 5 in 2011, and was added to Macs with OS X Mountain Lion in 2012. In 2020, Apple introduced a redesigned version of the Messages app with macOS Big Sur which added some of the features previously unavailable on the Mac, including location sharing and message effects.
