The recent arrests of 25 men in Florida for allegedly trying to have sex with children has prompted a sheriff there to issue another ‘app warning’ for parents.

  • Calculator% – Calculator% is only one of SEVERAL secret apps used to hide photos, videos, files and browser history.
  • Grindr – Grindr is 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 smart phone’s GPS location.
