Boo Cue

Know when the scares are coming.

Boo Cue listens to the horror film playing in the room, works out exactly where you are in it, and warns you a few seconds before each jump scare — with a vibration, a dimmed line of text, or an optional accessory that glows.

You still watch the film. You just stop being ambushed by it.

For whom

People who like horror and dislike being startled. People watching with someone who does. Anyone who has ever spent a film braced for the next bang instead of paying attention to it.

How it works, briefly

Pick the film. Put the phone face down. Boo Cue hears the soundtrack, matches it against a fingerprint of that exact film, and counts down to each cataloged scare. It keeps up if you pause, rewind, or skip.

Everything that matters happens on the phone. The audio is matched on-device and is never recorded or uploaded.

The accessory

An optional small device that glows amber as a scare approaches and red at the moment it lands — so you can look away from the phone entirely, or so someone else in the room gets the warning without a lit screen.

The device is not for sale yet. When it is, it will be listed on eBay and linked here and in the footer.
