The Elements by Theodore Gray is the gold standard for what educational software on a tablet should actually be. Instead of gamifying the periodic table with cartoon quizzes or point systems, it relies on incredible high-resolution photography, 3D interactive rotatable objects, and genuinely sharp science writing.
Every element opens with a living 3D visual sample — a chunk of native copper, a sparkling diamond, or a glowing tube of neon. Tapping deeper reveals a rich mini-essay explaining where the element comes from, how humanity figured out how to use it, and a collection of real-world objects made from it. It treats chemistry like a tangible mystery of the universe rather than a grid of numbers to memorize.
It costs more than a typical throwaway app store download, but it behaves like a permanent digital coffee table book. For any kid asking what the world is made of, this is one of the best tools you can put on an iPad.
