Elemio

Elemio is a beautifully crafted, interactive periodic table for macOS and iOS. Tap any of the 118 elements to explore its animated 3D atomic structure — electron shells orbiting a glowing nucleus that you can rotate and zoom. Each element page shows atomic data, electron configuration, common uses, and discovery history. Filter by category or period, and search by symbol, name or number. Switch instantly between English, Chinese, Japanese, Spanish and French — independent of your system language. An Element-of-the-Day widget brings a new element to your desktop daily. One-time purchase. No subscriptions, no ads, no tracking — Elemio collects no data and works fully offline.
