Authorities are warning parents about 15 apps that could be on your child’s phone or tablet and the dangers that come with them.

The Sarasota County, Florida Sheriff’s Office recently busted 25 people in an operation to protect children from online predators and human trafficking. Police say each suspect engaged in conversations on social media and mobile apps. Police say one of the suspects rode a three-wheel bicycle to a home while in possession of cocaine and another brought with him two firearms and several narcotics.

“Unfortunately, the internet allows for easy and anonymous access to children by strangers who are hiding behind a computer screen,” said Sarasota County Sheriff Tom Knight.

The apps include:

MEETME, a dating social media app that allows users to connect with people based on geographic proximity. The app’s users are encouraged to meet in person.

WHATSAPP, a messaging app that allows users to send texts, photos, voicemails, and make calls and video chats.

BUMBLE, a dating app. Kids have been known to use Bumble to create fake accounts and falsify their age.

LIVE.ME, a live-streaming video app that uses geolocation to share videos so users can find out a broadcaster’s exact location. Users can earn coins as a way to pay minors for photos.

ASK.FM is known for cyber bullying. The app encourages users to allow anonymous people to ask them questions.

GRINDR, a dating app geared towards gay, bi and transgender people. The app gives users options to chat, share photos and meet up based on a smartphone’s GPS.
