Is there an app that screams when you slap your phone?

Yes — and it's exactly as ridiculous as it sounds. Here's what these apps do, what separates a good one from a boring one, and how to get the loudest scream.

Short answer: yes. Spank Phone for iPhone reacts every time you slap the back of your phone with a sound and a cartoon facial expression. The harder you hit, the louder it gets, and if you keep slapping, things escalate.

What a slap-reaction app actually does

The idea is simple: you hold your phone in one hand and slap it on the back with the other. The app notices the slap and answers right away — a yelp, a scream, a dramatic face on screen and a buzz in your hand. A good slap app doesn't just react to "a slap happened"; it reacts to how you slapped, so a light pat and a full swing feel completely different.

How to get the loudest reaction

  1. Turn the volume up with the side buttons and check that Silent mode isn't on.
  2. Grip the phone firmly in one hand, screen facing you, fingers clear of the back.
  3. Slap with a flat, open palm in the middle of the back — a clean slap beats a clumsy one.
  4. Build up. Start gentle and increase the force: the reaction gets bigger as you go.
  5. Keep the rhythm going to chain slaps into combos.

And please: slap the phone over something soft, like a sofa or a bed. Our safety guide explains why.
