Countdown is a 2019 American supernatural horror film directed and written by Justin Dec, and starring Elizabeth Lail, Jordan Calloway, Talitha Bateman, Tichina Arnold, P.J.

[7][4][8] 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.

After avoiding getting into a car with her drunk boyfriend Evan, Courtney receives a notification stating she has broken the "user agreement".

When Quinn researches the app, she finds that similar deaths have supposedly occurred involving other users, but the public generally considers them to be fake.

After being attacked by a demonic figure in the parking lot of the cell phone store, Quinn meets a young man named Matt, whose Countdown states he will die in 18 hours.

Jordan receives a notification of her countdown changing to the original lifespan and is then terrorized by a demonic form of her and Quinn's deceased mother.

Sometime later, while visiting her and Jordan's mother's grave, Quinn receives word of Sullivan's arrest after more nurses have come forward, but discovers that an app called Countdown 2.0 has downloaded itself onto her phone, much to the sisters' horror.

[10] In April 2019, it was announced that Talitha Bateman, Peter Facinelli, Jordan Calloway, Tom Segura, P. J. Byrne, Anne Winters and Tichina Arnold had also joined the cast.

[citation needed] In the United States and Canada, Countdown was released alongside Black and Blue and The Current War, and was projected to gross around $5 million from 2,675 theaters in its opening weekend.

The website's consensus reads: "Countdown may offer a few fleeting jolts for horror fans with barren queues, but it lacks enough wit or creativity to leave a lasting impression.

"[6] The Verge's Charles Bramesco wrote, "The same horror devotees satisfied by the prepackaged premise and grace in execution of Happy Death Day will get everything from Countdown that's there to be gotten.

"[17] Kimber Myers of the Los Angeles Times was more positive, writing: "This isn't a subtle, moody film filled with a sense of unease; instead, jump scares are around every corner.

"[18] The Deseret News' Josh Terry wrote, "If you're looking for a few good scares that push the PG-13 boundary without breaking it, Countdown has fun with its clever premise.
