An air horn that goes off from a pocket. A cracked screen that wipes clean. A call that saves you from a meeting. Pick a prank, set a countdown, hand over the phone — then watch them jump. No internet, no account, no sign-up.
The Home screen, as it actually looks. Every tile is one tap from firing.
Four kinds of mischief. Every one of them a simulation.
Buzz! Sounds and feels like a real clipper — and reacts when the blade comes close to someone’s neck.
A charging pad that crackles and jolts the moment they touch it. Sound and vibration, nothing more.
A crackling jolt that makes everyone jump. No electricity is involved, ever.
Fake a shattered screen over a fake home screen and watch the panic. It wipes clean the moment you leave.
Blast an earsplitting horn out of nowhere. Several horns to choose between.
Sneak in a stinky sound at the worst possible moment. Countdown included.
Wail like the cops just pulled up outside. A sound effect — it calls nobody.
A high buzz nobody can ignore. It repels no actual insects.
Ring an imaginary visitor at exactly the right moment. Pick your favourite chime.
Swing the phone and it cracks like a whip. Motion-triggered, for an instant startled laugh.
Light a fuse, let it burn down, set off a booming blast out of thin air.
Honk like traffic just appeared right behind them.
An incoming-call screen on a countdown, so you can leave anything gracefully. In-app only — no real call is placed.
Pop up a text that sparks instant curiosity, with a chat thread behind it. Nothing is ever sent.
Hold a thumb down, watch the needle sweep, get a verdict. It measures nothing — and you can steer the answer.
A compatibility score with a dramatic build-up. The number is made up, and you can decide it in advance.
Pretend to scan a print for a top-secret vault. No biometric hardware is touched.
A hand-drawn skeleton cartoon, stamped NOT A REAL X-RAY on purpose. The camera never opens.
An innocent tap game that turns into a jump scare. The whole category can be hidden from Settings, so it never appears by accident.
From opening the app to someone leaving their chair.
Search the catalogue, filter by category, or go straight to your favourites and the pranks you opened last.
Choose a sound, then set a countdown — 3 to 60 seconds — so the prank fires long after you have put the phone down.
Or skip the timer and let a gesture do it: a swing, a wrist roll, a hand near the screen, or a volume key nobody notices you pressing.
The details that decide whether a prank works or falls flat.
Recorded effects on looping engines, matched to vibration patterns, so a clipper keeps buzzing and a taser keeps crackling instead of playing a clip once.
The accelerometer and proximity sensor let pranks react to a swing, a roll or an approaching hand — no tap needed, and no permission to grant.
The lie detector, love meter and fingerprint scanner can be steered ahead of time or live, with a gesture only you know about. Hidden from your victim, disclosed to the stores.
Every sound ships inside the app. Turn the network off and all 19 pranks behave exactly the same.
English, Tiếng Việt, 中文, 日本語, 한국어, Español, Português, العربية and ten more — taken from your device, or picked by hand.
Sound, vibration, animations and scary pranks each turn off on their own. A safety reminder appears on the way into every prank until you dismiss it for good.
Prank Box is an entertainment app. Every feature in it is produced with sound effects, on-screen graphics and vibration — nothing performs the real-world action it imitates. Never use it on anyone with a heart condition, epilepsy or anxiety, on anyone driving or operating machinery, or anywhere a loud siren would cause real alarm.
