Chladni Screen is a £1.99 pocket plate simulator

A small iOS and Mac app that draws Chladni figures from live audio input, with the mixed reviews you would expect at that price.

Narumi Inada's Chladni Screen simulates Chladni figures on screen and drives them from real-time audio, so singing or playing into the device changes the pattern. It runs on iPhone, iPad, Mac and Apple Vision, and is currently at version 2.2, dated 8 August 2025, with a colour-invert mode added recently. It costs £1.99.

The store listing frames the history correctly, crediting Robert Hooke's 1680 observation and Ernst Chladni's later work in 1787. That is a better provenance note than most cymatics apps manage.

Expectations should be modest. It holds a 3.8 average from ten ratings, and the reviews split between people who like the square-plate mode and people who find it thin or hit technical problems. For two pounds it is a reasonable way to get a responsive plate on a phone when you cannot carry a real one.
