MightyText (also known as 'free PC SMS') is a tool that lets you synch your Android device to your computer so you can send and receive text messages from the comfort of your own desktop.
Although keep in mind that all those text messages aren’t free (in spite of the app's name), as they'll cost the same as sending any text message using your phone's service provider.
In order for the app to work you'll need to install a special client on the device which you want to use it on. This client can be found as a Chrome extension, a Mozilla Firefox add-on, or a Safari plugin.
MightyText is a very interesting tool which lets you send text messages in an easier, more comfortable way. You won’t only be able to send SMS messages using your computer, but your tablet as well.
