True Random Numbers
Read full descriptionHide full description
Most random number generators calculate the numbers with pseudo random number generators. But this app leverages your device's motion sensors, swipes, or camera input, to generate authentically random numbers and shuffles. It also doesn't have a modulo bias, a common problem with random number generators.
