## What is TrueEntropy?

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 - even if your phone is resting on a desktop, it is able to pick up a sufficient quantity of thermal variations to generate random numbers at a rate of 18Mb per minute.

- Generate binary files for local use via AirDrop
- Send entropy to a destination machine via cryptographic relays
- Continuous generation mode to constantly reseed target machines

## Key features

- Generate true random numbers from thermal noise
- Utilizes smartphone camera sensor
- High volume entropy generation
- Output binary files locally

Спасибо 👌🏻

### 3/5 — Review

*2020-05-11*

I still don’t know what application this app has but I’m interested in quantum field generators, nonetheless. It could have applications that I could apply it to yet unrealized, so I may just keep it.

### 5/5 — Great tool

Solid tool for capturing unique

## Frequently asked questions about TrueEntropy

### How does TrueEntropy generate random numbers?

TrueEntropy uses your phone's camera to capture thermal noise variations in each pixel. These variations, stemming from fundamental particle physics, are then processed to create true random numbers at a high rate.

### What is the output rate of TrueEntropy?

The app can generate random numbers at a rate of 18 megabytes per minute, even when the phone is stationary. This continuous generation ensures a constant supply of entropy for your needs.

### Can I use TrueEntropy offline?

Yes, TrueEntropy can generate binary files for local use, which can be transferred via AirDrop. This allows for offline generation and use of random number data.

### Does TrueEntropy have ads?

No, TrueEntropy is ad-free. The app is completely free to use and does not display any advertisements, ensuring an uninterrupted user experience.

### What devices is TrueEntropy compatible with?

TrueEntropy is available for iPhone, iPad, and iPod devices. It requires iOS 11.0 or later to function correctly.

### How often is TrueEntropy updated?

The latest version of TrueEntropy is 1.0.3, which was released on April 19, 2021. While updates may not be frequent, the app is stable and functional.

### What is the age rating for TrueEntropy?

TrueEntropy has an age rating of 4+. This indicates it is suitable for users of all ages and does not contain any mature content.

### How does TrueEntropy compare to software-based random number generators?

TrueEntropy generates true random numbers derived from physical processes (thermal noise), which are considered more unpredictable than pseudo-random numbers generated by algorithms alone.

## Version history (last 2 releases)

### 1.0.3 — 2021-04-19
