This app is a digital replica of the Galton Board, a device designed to demonstrate the central limit theorem. 

Just put your phone upright, you can watch how the balls fall, hit pegs, take different paths, and eventually fall into different bins at the bottom. 

In the end, you will find the bins in the middle hold more balls than those on the sides. ## Key features - Digital Galton Board simulation - Demonstrates central limit theorem - Visualizes ball distribution - Interactive physics simulation - Educational tool for statistics ## Recent user reviews (4 of 4) All indexed reviews: https://appshunter.io/ios/app/galton-board-bean-machine/id1444632751/reviews.md ### 4/5 — It’s not Pachinko! *2021-10-04* This is a digital rendition of a device that lets one visualize the mathematical concept of a “Bell Curve.” There are some reviews for this app giving low marks, complaining about it not being fun or having scores, that it’s just balls falling down - well, a Galton Board isn’t meant to be a game, it is “just” balls falling, but in an elegant way that can be used for education. Maybe they thought it was a Pachinko game, which looks a bit similar? I like it (but I’m a weirdo that actually went in search of a Galton Board app). It would be great if the makers added a setting for it to act as if the board was perfectly upright, as it seems very sensitive to how you hold your phone. Also, perhaps adding a slightly faster speed (if you want to show how the randomness ends up in the same ordered bell curve almost every time). Despite my geeky review, it is also fun just to watch, the cascading balls bouncing off pegs is rather mesmerizing! ### 1/5 — So boring you might go into coma *2021-03-16* Watching a VIDEO of falling marbles is the OPPOSITE of entertaining game play on my iPad! ### 3/5 — Kinda cool *2020-04-07* A slow meditation... I found this kind of cool... relaxing... **Developer response:** Thanks for liking it ### 1/5 — Huh?! *2019-12-25* I opened the ap. The beads fell. I turned it upside down and poured them back. There is no ‘next’ no ‘re do’ no ‘score’ no levels of difficulty or any type of instruction button. It just pours beads back and forth. Have you the developer, actually attempted to play this? What is the point of the game? Am I missing something? Where is the “idea of normal distribution?” You have a center drop of beads that can’t be changed. Objects that they fall on, that are unmovable. Target slots that are fixed. The beads fall predictably, depending on the tilt of the device you are using What is the goal? This just looks like somebody who wanted an ap, (to get money from ads), but was to lazy to go through the work of actually developing one. You have changed your description, but the results are the same Comment after developers response. No ap makes me “feel bad.” **Developer response:** Hi Dave, Thanks for your review, I appreciate that. Well you got me. When I re-think about it, you're right, I totally missing the point in this app. It makes you feel bad, sorry about that man. I will reconsider the whole idea of this app. Thanks again for your honest. Niner ## Frequently asked questions about Galton Board ### What is Galton Board used for? Galton Board is used to visually demonstrate the central limit theorem and the principles of probability and statistics. It shows how random distributions tend to form a bell curve. ### How does Galton Board work? In the app, balls are dropped from the top and bounce off pegs, taking different paths. They eventually collect in bins at the bottom, illustrating how more balls accumulate in the central bins. ### Is Galton Board suitable for children? Yes, Galton Board has an age rating of 4+, making it suitable for younger learners to explore basic probability concepts in an engaging way. ### What devices support Galton Board? Galton Board is available for iPhone and iPod devices, offering a convenient way to learn on the go. ### How often is Galton Board updated? The app was last updated on December 1, 2019, with version 2.0.0. While updates may not be frequent, the core functionality remains stable for educational purposes. ### Does Galton Board have ads? No, Galton Board does not contain advertisements, providing an uninterrupted learning experience for users. ### Can I track my progress with Galton Board? The app focuses on demonstrating statistical principles rather than tracking individual user progress. It's designed for exploration and understanding of concepts. ### What is the learning methodology of Galton Board? Galton Board employs a visual and interactive learning methodology. Users learn by observing the simulation and understanding the resulting distribution patterns. ## Version history (last 5 releases) ### 2.0.0 — 2019-12-01 fix bugs ### 1.4.1 — 2019-09-10 fix bug ### 1.4 — 2019-04-08 fix bug ### 1.31 — 2019-02-24 fix bug ### v1.3 — 2019-01-07 fix bug ## Apps similar to Galton Board | App | Rating | Price | Category | | --- | --- | --- | --- | | [舒尔特方格-高效训练注意力和记忆力](https://appshunter.io/ios/app/id1541145568) | 4.6 (5) | Free | Education | | [Schulte Grid - Printable](https://appshunter.io/ios/app/schulte-grid-printable/id6547865783) | — | Free | Education | | [Magic Focus+](https://appshunter.io/ios/app/magic-focus-plus/id6444272284) | — | Free | Education | | [Schulte Table - Speed Read](https://appshunter.io/ios/app/schulte-table-speed-read/id1552536201) | — | Free | Education | | [Relay Flip:One Stroke of Color](https://appshunter.io/ios/app/relay-flipone-stroke-of-color/id1520989239) | — | Free | Education | | [纸・慧谷](https://appshunter.io/ios/app/id1570751030) | — | Free | Education | ## More apps by 乃君 黄 - [number conga](https://appshunter.io/ios/app/number-conga/id1448033540) - [Arrow Cube](https://appshunter.io/ios/app/arrow-cube/id1449451469) - [Simple Clock - Study With Me](https://appshunter.io/ios/app/simple-clock-study-with-me/id1462926848) - [Notify Here - A Location Alarm](https://appshunter.io/ios/app/notify-here-a-location-alarm/id1467489277) - [gravity detector](https://appshunter.io/ios/app/gravity-detector/id1480160202) All apps by 乃君 黄: https://appshunter.io/developer/1337343608 ## Related topics [galton board app](https://appshunter.io/ios/topics/galton-board-app) · [galton board](https://appshunter.io/ios/topics/galton-board) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
