App the Horror

Original title: 귀신 부르는 앱: 영

“The ones who shold never be sean... are now visible.”

Directed by Hyung Seul-woo

When the app is launched, a ghost appears. Developed by four young adults, the app becomes the centerpiece of a livestream where they venture into a supposedly haunted mountain to prove its authenticity—only to meet a grim fate.
