Mighty Text is an app that allows you to send and receive sms messages from your tablet! It syncs to your Android phone to accomplish this. Theme dev "djdarkknight" has decided to theme this as a standalone themed app. It was not possible to theme this in his theme chooser theme thanks to some hardcore small lines, so he decided to provide it separately. Everything has been blacked out in true darkknight style! This is pretty easy to install. You will need to grab the phone version from playstore and install that on your phone. Grab the themed apk from the source link below, uninstall the playstore version, install the themed version from the sdcard with package installer, sign into gmail and enjoy!
