Textalyzer is your answer if you have ever wished you hadn't sent "that" text the evening before!
Textalyzer utilizes 4 engaging and challenging games to analyze your state of mind. App users create their Forbidden List and use Textalyzer as a guardian of their texting behavior. If you can succeed in winning the games then you should be clear-headed enough to send out a coherent text.
You can also leave reminders to stop yourself from sending out text messages so you won't regret your actions later.
