Use your phone's camera as a high volume thermal entropy generator - creates genuine random numbers at a rate of over 18 Mb/min.
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, high volume entropy random number generator. No need to move your phone! Leave your phone stationary, and TrueEntropy will pick up a sufficient quantity of thermal variations to generate random numbers at a rate of 18Mb per minute.

iOS 12.0 and Swift 5.0 are required.
App depencies have to be installed using CocoaPods, which is a dependency manager for Cocoa projects. To install it, run:
$ gem install cocoapodsThen, run the following command:
$ pod installThen open TrueEntropy.xcworkspace file.
You can edit particular predefined constants (like camera resolution, range of acceptable sample mean etc) in Constants.swift.
