Plot
At a party, teenager Courtney is convinced by her friends to download Countdown, an app that seemingly predicts how long a user has left to live. Courtney is startled to see it says she only has 3 hours left to live. After avoiding getting into a car with her drunk boyfriend Evan, Courtney receives a notification stating she has broken the "user agreement". Returning home, she is attacked by an unseen entity and killed as her timer reaches zero. At the same time, Evan crashes his car and a tree branch impales the seat where Courtney would have been sitting.
Quinn Harris, a nurse who works at the hospital where Evan is admitted, dismisses his claims of a supernatural app, but subsequently downloads it only for it to claim that she has only two days left to live. Evan skips his surgery and is informed he has violated the user agreement. He tries escaping the hospital, but is confronted by an apparition of Courtney in a stairwell before being killed by the entity.
