Android Messages
Messages (Android Messages) is an SMS, RCS, and instant messaging application developed by Google for its Android mobile operating system. A web interface is also available. Launched in 2014, it has supported RCS messaging since 2018, marketed as "chat features". By April 2020, the app had more than a billion installs which was most likely due to Google's wider roll out of RCS to many different countries without carrier support.
