## What is Chladni Screen?

Chladni figures were geometric figures first discovered by Robert Hooke in 1680 and was researched and published by Ernst Chladni in 1787.

These geometric figures are typically rendered on a rigid, vibrating membrane made from materials such as metal, plastic, glass, or bowl, covered with grains, like salt and sand, and changes shapes in response to different sounds that are transmitted by mediums such as speakers and actuators.

The study of such phenomena is also known as cymatics.

Chladni is able to simulate the phenomena digitally.
A further 3 programs can be displayed by pressing and holding each of the 3 mode buttons.

### 5/5 — Awesome!

*2026-05-01*

So honorable.

### 1/5 — What is the point? Waste of time and money

*2025-10-22*

What a waste of money. What was the purpose of this app??
You can’t enter a frequency and see what pattern that frequency will produce.
Don’t bother

### 2/5 — Parlor trick

*2025-09-20*

I think it just makes different 
Kaleidoscope type pictures every time you say something. If I repeat the same word the picture should come out the same or pretty similar but it would show something totally different each time. I don’t think it’s accurate. I just wasted $1.99.

### 5/5 — アップデートありがとうございます

*2025-08-12*

iPadで大画面で正方形全体の図形が見れてすごく興奮しました！！めちゃくちゃかっこいいです！丁寧なサポートありがとうございます💖💖💖買ってよかったアプリです👍✨

### 2/5 — Circles and blocks not working

*2025-02-14*

I’m using iPhone 16 pro and iOS 18.3. Just downloaded the app. Squares is lovely but circles & blocks features don’t work at all. Just a black screen.

### 5/5 — iPad version no longer allows for mic volume access

*2025-02-08*

Lost the ability to change the volume of the mic on the iPad version. Fix it Jesus!

### 4/5 — Very Fun!

*2025-01-05*

I’d actually give Chladni a 4.5 but would be an easy 5 star if we could apply color options to the patterns. Any chance of adding a color selector to the app?

### 4/5 — 非常に良いがipadmini6でボリュームゲージが枠外に

*2024-09-07*

iPhoneでは問題なく使えるがipadminiだと最下部のボリューム調整がはみ出て操作できない。
再インストールもしてみたが変わらずです．
修正お願いします。

### 4/5 — Very Cool

*2024-09-04*

I’d like to suggest that each sand grain leave a fading trace or fading memory of where it’s been, kind of like a blip on a radar screen. Also, find some way to add color. Assign color to the vibrating sections of the membrane instead of just dots where the membrane is not in motion.

### 5/5 — A true portal

*2024-04-29*

This the first gate…
