Fan-made music videos are wildly popular among teens and Millennials on YouTube and Vine. But actually creating these DIY clips is a little difficult, especially if they’re only working with a smartphone. New app Eyegroove makes it easy by putting content in their hands, partnering with SoundCloud to offer millions of songs to pair with videos. Users can enhance their creations, called Grooves, with several special effect options, and share with friends on the “built–in social network.” Eyegroove is reportedly very popular with teens, and especially teen girls.
