ToothPixie New Apple App on App store:Open your Mouth Wider:

Have you ever been to a dentist who says do you open your mouth wider?
 You want to say something funny like I need vice grips on my mouth to open my jaw. Finally for kids or anyone that allows you to speak to the dentist instead of his hand.
Try this incredible useful tool Free Before you Buy the ToothPixie.
 Everything is a discounted price instead of buying each separately BUT don't wait to long

 Try our basic model for free.Which includes 17 free commands that you would use with your Dentist WITHOUT voice activation. Here are some of the basic FREE Commands:
 My mouth does not get any wider. That Hurts. I have to swallow.When can I get up?Can I have more pain Killer?

We found this am that ToothPixie inherently follows Apples rules regarding kids. If a user has active restrictions then the features can't be bought so release the restriction.

One purchase = right to use on all devices signed by same Apple ID
 
It's just that the way inapp purchases works, Apple requires that a single purchase against a single Apple ID should apply to all devices owned by that Apple ID
