Hello, my daughter has her learner's permit and just started driver's education. My state prohibits all cell phone use while driving for anyone under age 18 (and texting for all drivers). They do allow you to use navigation. Is there an app that will send all calls to voicemails and hold all notifications while navigation is in use? I definitely don't want text messages popping up on her screen while she's driving. I normally would just tell her to turn the phone off and put it in her purse, but navigation is actually useful. I'm sure I'm not the first parent to look for such an app. Anyone have any recommendations?
