Hands-on chemistry — build real compounds as you learn
Build your own 186 compounds with drag-and-drop chemistry, watch atoms spin in a live animation, and hear the story behind every element. All 118 elements, fully offline.
Our app
Digital Lab
A Periodic Table App for Curious Minds. Explore all 118 elements with rich visuals, pronunciations, and discovery history — entirely offline, on macOS, Windows, or Linux.
All 118 elements, offline
Every element bundled locally with images, audio, and discovery history — no internet connection required.
Eight ways to explore
Switch between atom symbols, uses, name origins, discoverers, samples, atom structures, discovery countries, and videos.
Interactive chemistry lab
Drag elements together to form real compounds and see how bonding actually works.
Build your own atom
Add protons, neutrons, and electrons by hand and watch stability and isotopes update live.
Narrated lessons
Step-by-step audio lessons walk through each element's structure and story.
Meet the discoverers
See who discovered each element and when, brought to life with character art and short bios.
