Just randomly bought and played around with this, and as a sound designer / (visual) artist, plus someone who’s fascinated with physics, including quantum mechanics, which this absolutely relates to in terms of fields of probability, this is great. A couple features I’d really love to see in addition to the mic input suggested in another comment, would be to feed Audio Unit app sound into it, or at least be able to choose from some other basic waveforms (i.e.: pure sine, triangle, saw, and square waves - ideally with pulse width modification as a bonus). That could really elevate the reusability of the app. Also being a software/web developer as a day job, I could see expanding this in plenty of other fun ways, like color gradients/themes for the digital “sand” particles here, and so on. Anyway, great work so far and hats off - hope this continues to be developed!

I was about to spend a lot more for a physical Chladni plate and came across this app. It is nearly perfect. I have only 2 asks that I think would make it even better:1) an option to switch to sliders for the M and N values (and maybe manually enter them),2) an option to “normalize” the spread of the sand because drawing is fine, but the assymetric spreads really triggers something in me.

UPDATE: I love the new changes. More like using a real signal generator. BUT I really miss the graph at the bottom to adjust the tone. It was a way to explore frequency that you can’t in reality. Learned a lot from that mode. Is it possible to add it back in as a secondary option? And I miss the “clamped vs unclamped” option as well. But I’m just being picky, this is a really great app. I can’t believe someone took the time to create this. This is the best Chladni Plate simulator in the App Store. Really, it’s the ONLY ONE. There’s a difference between a Chladni and Cymatics. Cymatics mainly uses water & light whereas Chladni Plates uses sand on a plate. If this developer could make a Cymatics app like this, I’d be over the moon! Either way, big props to the developer of this app!

It doesn’t seem to react to sound input, I think it’d be a big improvement, or I’m missing how to turn it on
