Gruselknopf

Spooky sounds from afar

One phone is hidden in the room. With a second one you trigger spooky sounds from a distance, as often as you like. Your guests won’t know where the screaming comes from.

App Store: coming soon

How it works

1. Room device

   An old phone or tablet shows a QR code. Start it until a set time and put it in its place in the room. After ten seconds the screen goes almost black.

2. Remote

   Scan the code with the app. Or without any app: open the link with the camera, share it, or type the five-letter code in the browser. Over Wi-Fi or mobile data.

3. Scare

   Pick a sound or “Random”, then press “Scare”.

Sounds

Over 20 sounds in four groups, all included in the app.

Handy details

• iPhone, iPad and Android work together: the room device can be an Android phone and the other way round.
• Apple Watch: scare straight from your wrist.
• A button in the notification on the lock screen, without opening the app.
• A silent connection test shows whether the room device is reachable, without any sound.
• No account, no ads, no tracking.

Please only scare where everyone is up for the fun.
