Growing number of apps let parents control children's smartphones

Children at younger ages are frequently using smartphones or tablets, and that has led to some problems for parents trying to limit technology use. Since 2011, children smartphone and tablet use has tripled, according to Common Sense Media, and that number is expected to only accelerate further.

The DinnerTime Parental Control app, designed for both Apple iPhones and Google Android devices, will let parents pause activity - giving children the chance to finish schoolwork, exercise, finish chores, or other activities. There also is a feature so parents are able to purchase app usage details, giving them a better look at how much time kids are using certain apps on their devices.

However, critics say parents should speak with their children about appropriate and inappropriate use of their devices - but that won't slow down the market for apps that provide parents with a better ability to limit technology use.
