13WOWK reports that police departments across the United States are reminding parents to watch out for certain apps on their child’s phone. The Sarasota County Sheriff’s Office in Florida has published a list of apps that people should watch out for their children using, including multiple social media apps, dating apps, and apps that hide content.
