According to the Daily Mail, there is a smartphone app that is very dangerous for your kids.

A district attorney in Alabama by the name of Pamela Casey has posted a video warning parents about a calculator app that allows children to hide photos and videos from their parents.

This app looks similar to a regular calculator and can be used as such. But the app has a dangerous side that allows your kids to input a secret pass code that will unlock images and photos that your children want to hide from you.

Tech experts are saying the app is one of many types that allow kids to keep secret photos and videos. So do you know what is really on your kids' phone?
