3D Molecule & Atoms Chemistry vs C++

Stop guessing what a molecule looks like from a flat diagram. See atoms, bonds, and shapes clearly in 3D so chemistry makes more sense, whether you are studying for class, teaching, or just curious. 3D Molecule & Atoms Chemistry helps students, teachers, and curious learners explore molecules, atoms, and the periodic table in a way you can actually see. Open the 3D Molecule Lab and rotate any model with a drag, zoom with a pinch, and double-tap to reset the view. Switch between Ball & Stick, Space-Filling, and Wireframe to focus on structure the way you want. Tap Explode to spread bonds into an easy-to-read view, then tap again to bring them back. Open Info for the molecule name and formula, atom and bond counts, category, a plain-English explainer, and a quick note on where you might encounter it. Search the catalog by name or formula, then jump into entries like water, carbon dioxide, methane, benzene, glucose, caffeine, aspirin, and more. Study chemistry from more than one angle in the same app. Browse all 118 elements in the periodic table, filter the grid by groups like noble gas or transition, and tap any element to open its atom in the 3D Lab. Read lessons on atoms and elements, chemical bonds, states of matter, periodic trends, functional groups, acids and bases, stoichiometry, and common reactions, then use the inline Open the molecule buttons to see the exact model being discussed. Test yourself with quiz decks, get a one-line hint that does not reveal the answer, read the explanation after each question, and jump from a question straight to View this molecule in 3D. Keep chemistry close at hand without extra setup. The Molecule of the Day widget can sit on your Home Screen, Lock Screen, or StandBy view, and a quick control can open today’s pick in the lab. You can also find molecules and elements from search and open them straight into 3D. The app works offline for its built-in chemistry content, asks for no permissions, and the plain-English explainers and quiz hints stay on your device when that feature is available. It fits real study and teaching moments. Review functional groups on the bus, then tap View this molecule in 3D to rotate the question’s model. Open caffeine from search when you want to see what it actually looks like. Put benzene on screen while teaching and rotate it live as you explain aromaticity. Read about hybridization in Lessons, tap methane, and use Explode to make the shape easier to understand. Build a small daily habit with the Molecule of the Day widget. Pro adds more to explore: a larger molecule catalog, more lesson chapters, more quiz decks, reaction animations with play, pause, and restart controls, and extra atoms in Molecule Builder for creating and saving your own structures. Free users can still try one Pro molecule each day, and selected locked content can be opened once by watching an ad. Restore Purchases is available in Settings. If chemistry feels abstract on paper, start seeing it in 3D today. Terms of Use (EULA) - http://www.apple.com/legal/itunes/appstore/dev/stdeula
