Because apps change often, this is only a partial list of popular apps among students. Not all of these apps are used in negative ways, but parents should be aware of apps their kids are using and how they are used.
"Almost all of the 7th and 8th grade students [at my school] use this app. But because of people using their anonymousity [sic] for evil, rumors have been spread, secrets have been told, and lives have been ruined. I am begging you, please either take off the anonymous option or take down this app altogether. Please. All this has done is create drama, enemies, and rumors -- some even towards me. I am sick of being a target, I am sick of being humiliated, and most of all I am sick of anonymously being told terrible things about myself."
