GCRC is right. It is free but how many students or parents know about phoneguard or know how important it is not to text and drive. This will take awhile to get the word out just like wearing your seatbelt was. Don't think i every saw a concert on wearing your seatbelt. lol
I think as more and more people are aware of this distracton while driving and the solution is phoneguard OPMG will get more apps being bought and revenue will rise.
