Wilhelm Drop
Make dropping your phone a laughing matter.
A drop-detection utility for iPhone. When your phone falls, Wilhelm Drop plays the Wilhelm Scream — the most famous scream in cinema history.
ABOUT THE APP
Wilhelm Drop uses your iPhone's built-in accelerometer to detect freefall in real time. The moment it senses a drop, it fires your chosen sound instantly — before your phone even hits the ground.
Built for film people, audio geeks, prop masters, sound designers, and anyone who has ever watched their phone tumble in slow motion toward a hard floor.
THE WILHELM SCREAM
The Wilhelm Scream is a stock sound effect that has appeared in over 400 films and television shows since 1951 — from Star Wars to Lord of the Rings to Indiana Jones. Recorded for the 1951 western Distant Drums, it became Hollywood's most-used inside joke, passed between sound designers like a secret handshake for seven decades. Now it lives on your phone.
FEATURES
Drop Detection
Real-time freefall detection using your phone's accelerometer.
Adjustable sensitivity lets you tune the trigger to your environment — from a cautious fumble to a full-contact smackdown.
Landing Sounds
Choose separate sounds for soft and hard landings with adjustable sensitivity, delivered with perfect comedic timing.
Custom Sounds
Import any audio file from your device or record your own. Wilhelm Drop automatically trims leading silence and finds the nearest zero-crossing so your sound fires instantly with no lag and no click artifacts.
Volume Control
Set your own playback volume independently of your phone's ringer. Option to override system volume so the scream fires at full force regardless of your phone settings — even on silent.
Sensitivity Control
Dial in exactly how weightless the device must feel to count as freefall, and how long that weightlessness must persist before the scream fires. Eliminates false positives from quick tosses or
sudden movements.
Works When Locked
Optional background mode keeps Wilhelm Drop listening even when your screen is off — so you're covered whether the phone is in your hand, on a table, or sliding off the edge of your desk.
Privacy First
No ads. No tracking. No account required. Wilhelm Drop collects zero data. Motion sensing and audio processing happen entirely on
your device and never leave it.
