What it is

Open-source true random number generator for iOS — TrueEntropy uses your phone's camera to generate true random numbers derived from thermal noise. The camera in your smartphone is so advanced that it can detect even the smallest variations produced by fundamental particle physics. We capture thermal variations in every pixel of your phone's camera to create a powerful random number generator. [iOS, iPad, Open Source]
