With a new app parents can lock their children’s mobile phones until they answer questions in Science, Maths, and History.

With Studylock, children must answer questions each time they unlock their mobile or even try to open apps.

According to a recent study by Pew Research Center’s Internet & American Life Project:

"Smartphone adoption among American teens has increased substantially and mobile access to the internet is pervasive. One in four teens are "cell-mostly" internet users, who say they mostly go online using their phone and not using some other device such as a desktop or laptop computer."

The research says teens will open up their phones between 25-100 times a day to play games, login to Facebook, use the internet, or text friends.

With more and more teenagers becoming addicted to the internet, StudyLock gives parents control over excessive usage by implementing education into teen mobile use.

"Teens are not going to use their cellphones less. Better to make them learn every time they use their smartphones, tablets and computers."

Parents can configure the device to open off of standby with 20 question and then another 20 questions for each app they want to open.

But for parents serious about their childrens education there is more. StudyLock has a unique grading system incorporated into the app which grades children’s performance in each subject and overall. The grades are emailed to parents so they may monitor a childs performance and identify strong and weak subjects.

Premium members are afforded in-depth analytics to their child’s mobile usage and interaction with the app.
