MolNexus: Molecule Chemistry

MolNexus — Molecular Chemistry Learning, Offline

MolNexus is a fully offline educational reference app for exploring drug molecules, molecular structures, chemical properties, and functional groups. Designed for students, chemistry enthusiasts, and anyone curious about the building blocks of pharmaceutical compounds, MolNexus puts a curated chemistry library right on your device — no internet connection required.

WHAT YOU CAN EXPLORE

- Molecule Library — Browse a curated collection of real molecules with structured data: molecular formula, molecular weight, chemical classification, functional groups, and original educational descriptions.

- Functional Groups — Learn to identify common functional groups such as hydroxyl, carbonyl, carboxyl, ester, ether, amine, amide, halide, and aromatic rings, along with their key structural patterns and characteristics.

- Chemical Properties — Every molecule entry includes clear, structured chemical data to support focused study and quick reference.

- Search & Filter — Instantly search by molecule name, formula, chemical class, or functional group, and filter results to find exactly what you need.

- Favorites — Bookmark molecules you want to revisit for faster access during study sessions.

- Quiz Mode — Test your knowledge with quiz questions generated from the app's own bundled dataset, covering formulas, chemical classes, functional groups, and molecular weight.

- Light & Dark Themes — Switch between a clean light interface, a purpose-built dark theme, or match your system setting.

WORKS FULLY OFFLINE

MolNexus requires no internet connection, no account, and no login. All educational content is bundled directly with the app, so it works anywhere — including Airplane Mode. There are no ads, no analytics, and no tracking of any kind.

EDUCATIONAL USE ONLY

MolNexus is strictly an educational reference tool. It does not provide medical diagnosis, treatment recommendations, prescriptions, or dosage guidance. Always consult a qualified healthcare professional for medical decisions.

PRIVACY-FIRST BY DESIGN

MolNexus does not collect, transmit, sell, or share personal information. The only data stored is kept locally on your device — such as your theme preference and favorite molecules — and is never sent anywhere. Full details are available in the in-app Privacy Policy.

Whether you're a chemistry student, an educator, or simply curious about the molecules behind everyday medicines, MolNexus offers a clean, distraction-free way to learn — anytime, anywhere, completely offline.
