SMS Sender is an app (or website) that allows users to send short messages (SMS) to other mobile phones. It provides an easy and convenient way to stay in touch with friends, family, and colleagues. With an SMS Sender app or website, users can send text messages, images, videos, and audio files. They can also schedule messages to be sent at a later time. Some SMS Sender apps also come with advanced features such as group messaging, auto-responders, and delivery reports.
Discontinued It seems that the application is no longer maintained: it is no longer on Google Play Store and the site http://desksms.appspot.com/ does not work. The APK can be downloaded from http://www.clockworkmod.com/ and the source code can be found at https://github.com/ClockworkMod/DeskSMS
