Chemistry 3D: Molecule Lab

Snap, scan, import or type a chemistry problem and Chemistry 3D works it out step by step, with a chart and the molecule in 3D. Build molecules, explore all 118 elements and run virtual experiments. Free, no account; the chemistry works offline.

SOLVE PROBLEMS STEP BY STEP
• Type, paste or say a problem, take a photo, scan pages, or import photos, videos, PDFs and Word files. You can also share them to the app from other apps
• Text in photos and scans is read on your device
• Worksheets are split into questions: solve one, or the whole sheet at once
• 20 calculators show every step, from balancing and stoichiometry to pH, titration, equilibrium, kinetics, thermodynamics and electrochemistry
• Export a worked solution as PDF, Word, GIF or video

BUILD IN THE LAB
• Tap to place atoms; hydrogens fill in and each structure is checked as you build
• VSEPR shape with bond angles, polarity and Lewis structures
• Import SMILES, a name, a formula or a molecule file; export PNG, SVG, MOL, SDF, XYZ or PDB

EXPLORE
• Periodic table colored by group, block, state or trend, with heat maps, charts and a 3D skyline
• Element pages with a sample photo, a 3D atom, the electron configuration and everyday uses
• 644 molecules in 3D to explore and compare
• Orbitals in 3D, electron configurations and MO diagrams
• 60 reactions with balanced equations, and 8 mechanisms with curved arrows and energy diagrams
• 6 virtual experiments with live graphs: gas laws, acid–base titration, equilibrium, kinetics, solutions and galvanic cells

LEARN AND TEACH
• 24 guided lessons following AP Chemistry Units 1–9, each with a short check
• Practice by topic with mastery tracking and review
• A 232-term glossary
• Sources on lessons, molecules, reactions and terms (OpenStax, IUPAC, NIST, PubChem) and a Report an error link
• Explanations of what you see, built from the app's own numbers
• Teaching decks with pen, laser pointer and a second screen or TV

WEAR OS APP WITH TILES AND COMPLICATIONS
A Wear OS app that runs on the watch without your phone, works offline and has no ads:
• The periodic table of 118 elements with search, and element pages with atomic mass, electron configuration and electronegativity
• Molecules you turn with the crown or bezel, and 12 VSEPR shapes in 3D
• Molar mass, pH and gas law calculators
• Tiles: Element of the Day and Molecule of the Day tiles show a new element and molecule every day; tap a tile to open it
• Complications: Element of the Day and Molecule of the Day complications for your watch face, as short text, long text or a small image; tap to open the app

PROJECTS
Your work is saved on your device, with versions, a 30-day trash and .chem3d files to move projects between devices.

20 LANGUAGES
The interface and the content (elements, molecules, reactions, lessons, glossary) in 20 languages.

FREE, WITH ADS
Chemistry 3D is free and supported by ads. Some extra lessons, reactions, simulation scenarios and tools open when you choose to watch two short videos: lessons, reactions and scenarios stay open for good; tools such as Solve all or Word and video export stay on for 24 hours. In the EEA and the UK you choose how ads use your data, and you can change it any time in Settings › Privacy choices.
