Occasionally effective horror story about a haunted phone app that tells victims exactly when they'll die. A plucky nurse (Elizabeth Lail) becomes the chief opponent of the demon (Dirk Rogers) behind it all, defending her younger sister (Talitha Bateman) with the help of a quirky priest (P.J. Byrne) whose methods are occult rather than Catholic. Though writer-director Justin Dec's film is quite clearly aimed with precision at teens, the amount of vulgar talk included in the dialogue precludes its endorsement for them.

Watch out for: An occult theme, some gore, brief physical violence, a few profanities, frequent crude language.

Rated: A-III, adults; MPAA: PG-13
