## Galton Board App Description
Unlock the power of probabilities and explore the beauty of mathematics in motion with the Galton Board App. This innovative application transforms your mobile device into a dynamic, interactive probability demonstrator that brings centuries-old mathematical concepts to life. The app utilizes your iPhone's and iPad's gyroscope capabilities, creating an immersive experience where the beads appear as if they are rolling around inside your device.

The Galton Board was invented by Sir Francis Galton in 1873 to illustrate the binomial distribution. Through our app, we've recreated this educational tool to demonstrate how, with a large number of beads and rows of hexagons, it approximates the normal distribution - a concept known as the Central Limit Theorem.

Key Features:

•	An interactive Galton Board that displays the principles of probabilities and the binomial distribution.

•	Detailed explanations of related mathematical concepts, including probability theories, independent identically distributed (IID) random variables, regression to the mean, the law of large numbers, the random walk, the Gambler's Fallacy, and more.

•	A "Stock Market Data" version, simulating the probabilities of a range of historical monthly market returns, and demonstrating their correlation with the binomial distribution.

•	The 'Historical Monthly Return Beads' featured with the Stock Market Data, where beads fall through the board based on monthly historical returns for a choice of 20 index portfolios.

•	Pause or slow-motion options to study the bead movement and distribution patterns in detail.

The Galton Board App is ideal for statistics, math, and stock market enthusiasts. It is not just an app, it's an immersive, hands-on approach to understanding probabilities, the binomial distribution, and the stock market behavior. Presented by Index Fund Advisors, this app is your go-to educational tool. Download now and embark on a fascinating journey into the world of probabilities and the "law of unreason" as referred to by Sir Francis Galton himself!

## Galton Board App Reviews in United States

### ***** "Great product for stats student and fans"
Love this product. The first time I saw a Galton Board was the the Science Museum in Flushing, NY. My mind was blown. 

I am so glad that a proper digital version was created. It would be awesome if Index Fund Advisors, Inc. could bring the physical product back.
-- EJ's App, 2024-05-14

### ***** "Super helpful for my class!"
This app was great for helping me understand the concept of bell curves for a class I’m taking this semester! I’m glad it’s out there for students like me :)
-- emmitt687, 2024-05-08

### ***** "This app helped me understand bell curves"
Caden Fuentes! 

Using this app I was better able to understand what a bell curve was and how to read a bell curve! I showed this app to a few of my friends who are in economics and they were just as impressed as I was on how awesome this app was! It helped me learn and studying for a test that had a few bell curves on it! Over all great app!
-- Beast mode3737, 2024-05-03

### ***** "Cool!"
Math in motion? Yes, please!
-- Prtuyo, 2024-05-02

### ***** "Great app!!"
Professor used this to demonstrate content in class and it helped me understand it so much better!
-- I can't think of a nick name?, 2024-04-30

### ***** "Review"
An amazing review love this app I use it daily!
-- Ethan H.5688, 2024-04-24

### ***** "Awesome App"
This app is awesome and super easy to use!!
-- White bronc, 2024-04-23

### ***** "Amazing and beautifully designed"
This app has many levels. To fully ‘get it’ one has to know quant finance, some distributions theory ( Binomial and Gaussian) and Efficient Markets. 
The golden bead is what Active investors should simulate and see where they land. That will convert them to index investing. As an aside by tilting your mobile device you can skew the distribution. Fun! 
The team that must have coded it also did a great job. A must have for quants or even Dads showing their kids that math 🧮 can be fun!
-- OakTree2024, 2024-04-22

### ***** "Super helpful!"
Omg! This app is amazing! Really helpful! Using this app I was able to better understand the use of a bell curve!
-- adisonnlee, 2024-04-09

### ***** "PSYCHOLOGY EXTRA CREDIT"
thus app is literally soooo amazing!! It helped me understand the statistical side of my psychology class and it deserves way more downloads and reviews!! Will definitely be recommending it to others!!
-- Melanie Wills, 2024-03-30

### ***** "Great App!!"
This app is actually really helpful! Great app!!
-- JWills2023, 2024-03-26

### ***** "Amazing!"
This app helped my daughter understand the theorem and helped her with her homework.
-- Karenbrooks96, 2024-03-25

### ***** "Historical investment insights"
This app is cool from the standpoint of understanding how the market works. It provides an overview of how the stock market works and that rates change over time with the ups and downs of the market. Overtime most investments will fall in the range within the Bell curve and determine the rate of return. Again a very cool app.
-- Steve - CO, 2024-03-21

### ***** "Super interesting"
It’s fascinating to be able to view data in this way and the app is super convenient. Really helpful in my stem classes.
-- CanyonH, 2024-03-21

### ***** "Really awesome app!"
Love this app so much!
-- Mason Bellieu, 2024-03-21

### ***** "Galton Board-Bell Curve"
This is such a great app! This app is extremely useful and helps me understand Pascal’s triangle! I totally recommend getting!!
-- Stan Whittle, 2024-03-21

### ***** "Galton Board App"
This app is amazing and it’s very intricately made!
-- Luke V.., 2024-03-20

### ***** "Very helpful to better understand!"
Using this app, I was able to better understand the use of the bell curve. This helped me to study for my exams to make sure i can fully grasp this idea. The app is very easy and simple to use. It is clear and direct to make sure you fully understand. I like how the math equations for why this statistic works is added on the side too incase that interests you as well, or if you just want to know why! Overall, definitely an app I would recommend whether it be for educational use or just for fun.
-- mil_monkey, 2024-03-20
