Very cool. Would like a line-in (if possible) option and add-fre verison. Maybe br able to change colors beyond selections - But I am complaining too much. This is Very Cool and it is almost exactly what I was looking for for at least a temporary solution for my Hi-Fi setup. It looks very cool and it looks like a component. Great job!

You can try modifying a hands-free kit to be able to use it as a line-in input.

Easy, accurate and fun...simple to set up, with variable sensitivity. I was contemplating buying a stand-alone audio frequency display for my home audio rig, and I tried several other apps, but I really like this one; now I don't need to buy more equipment!⚡🎶🎸😎👍 (I never give 5⭐, not even to myself, so please don't take it personally! Consider 4⭐ as batting 1000...good app!)

Great app, very responsive to sound. Got a couple of suggestions and would make it perfect, hence minus 2 stars. Firstly, there should be a paid version to get rid of that stupid add at the bottom. 2nd, there should be a HD version as it's not crystal sharp, and thirdly, be able to choose your own colours, these 3 would be great in a paid version if you could do it, then you'll get top marks!
