A lot or a little?
Parents need to know that Don't Text Me is a free app that's meant to curb the growing problem of texting while driving. It's aimed at teens and easily-distracted adults, but works equally well for students who bring their phones to class. However, while admirable, the app doesn't actually prevent texts from coming through. Instead, it's serves as a broadcast service, letting friends and colleagues know that you'd simply prefer not to received texts. If they choose to ignore your request, you'll still hear the chime and be tempted to read the message.
