Not sure what EasyFF is and I googled it as well. Maybe include a description of what the app is useful for?
I like
-Snapchat
you can use it to send pictures/short vids that self destruct after a certain time without giving away your number
-Kik
"text message" people without giving away your number. Can send pics and shorts vids with it too I believe.
-Instagram
social media site used for posting pictures/short videos with colorful filters. *no nudity*
-Vine
social media site used for posting short vids
Love love love this thread! Really hope we can see some more input
