About this app
Trick your friends with a ‘detector’ that you secretly control. Press the screen harder to control the readout and realistic 'geiger-counter' sound. Use it on your friends to measure their style, intelligence, and wit. Wave it around when you ‘detect' BS, bros, or sheer brilliance. Detect engrams, elronds, megafaunas, and more. It’s amazing what your phone can 'detect'! Works on old and new iPhones, even those without 3D-touch! How it works: On phones with 3D Touch (6s, 7, 8, X, XS), the readout is controlled by measuring the PRESSURE on your screen. On all other phones (iPhone 11 and newer, iPhone 6 and older), the readout is controlled by the SIZE (DIAMETER) of your fingerprint on the screen. TIP for the fingerprint-size-sensing phones: lay the length of your finger against the screen to get up to and above 100%! Edit the labels to whatever you like, or leave them blank for versatility. Can also be used as a 'musical' instrument or for sound effects. Have fun!
