Detecto — the Real Fake Geiger Counter

By Bryan Wu

This app is only available on the App Store for iOS devices.


Trick your friends with this amazing ‘detector’ with a secret that you control.

The harder you press the on-screen button, the higher the detector's readout and more frenzied the 'geiger-counter' sound.

Use it on your friends to ‘check' their engrams, intelligence, sexiness, or foolishness. Use it to ‘detect’ nearby pizza. Use it on trees and show how your iPhone can ‘detect' wood.

How it works:

If you have the 6s it uses 3D Touch and you’ll get super-detailed control over the readout, but guess what: It even works on the iPhone 4s, 5, 5s, 6, and SE!

“But wait, my phone doesn’t have 3D Touch, how did you do this?!”

The answer: super-secret coding techniques and the discrete movement of your thumb (roll the length of your finger against the screen to max out the readout on these older phones).

TIP for older phones: lay the length of your finger against the screen to get up to and above 100%!

Have fun!
