While today’s teens may still do this, modern technology has given them dozens of other ways to meet and contact potential partners, from social media and chat apps, to online communities and dating websites. Although Tinder does not allow users under age 18, there are plenty of other apps your teen may use to connect with strangers online, including using a fake birthdate to bypass the system.

In 2016, Influence Central reported that the average age kids get a smartphone is 10 years old. This age continues to drop as more parents are purchasing internet-connected mobile devices for their children: Common Sense Media found that 42 percent of American children ages 8 and younger now have their own tablet.

Companies have been quick to cash in on this growing younger demographic by creating kid-focused apps like Facebook Messenger Kids – a chat tool for kids to communicate with parent-approved contacts – and video creation and sharing app Musical.ly. With the increasing number of programs geared toward children, it’s up to parents to monitor usage and set boundaries to avoid endangering their kids.
