Are there age restrictions for your apps?

Yes. For WIllpwr⁺ SE, which deals with sexual excess, we've restricted customers to those over 17 unless their parents approve of the purchase.  We know that most middle schoolers have seen porn before they graduate and that many teens will form strong porn habits or develop other sexual excesses before age 17, but there's really no way to sell or market our apps to teens without parental approval.

For Willpwr⁺ EE, dealing with emotional eating, we recommend kids 13 and older could use the app quite effectively.
