Pay no attention to those who obviously don’t have the intellect to understand or appreciate this product. Even if you have never solved the time independent Schrodinger equation for a central potential in three dimensions you can still enjoy this software. In essence, what it shows is the places where you would most likely find an electron in “orbit” around a hydrogen nucleus for the different energies the system can possess. Although this problem was mathematically solved early last century, methods of visualizing the complex mathematical functions as elegantly as simply as this are relatively new. Van Gogh’s Starry Night was painted a long time ago that doesn’t mean it isn’t beautiful or isn’t important today. Ten dollars is inexpensive if you know what it takes to put something like this together. I would have paid double that. If you have done the math you will love this software. If you haven’t but you do have an open curious mind you can still appreciate it's beauty and maybe use it to inspire you to learn more about the fascinating subject of Quantum Mechanics.

I am they chemistry instructor and this app is immensely helpful for teaching about orbitals! PLEASE update it - it no longer works with iOS 11!

But it's not like there are any other applications that give hydrogen orbitals

Pretty cool, but it crashes every time on my iPod Touch.
