App the Horror

Story Line

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.

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