Mol Geo

🔬 Mol Geo — Learn Molecular Engineering Interactively

A free educational app that helps you understand molecular engineering, molecular shapes, chemical formulas, and the VSEPR (Value Electron Pair Repulsion) theory in a visual and interactive way.

Discover how molecular shapes are determined by the number of electron regions, bonding pairs, and free pairs, and view and interact with 3D molecular models from all angles.

Whether you're a high school student, a college student majoring in chemistry or science, or a teacher looking for a modern teaching tool, Mol Geo helps you easily study and understand molecular engineering.

✦ Key Features

🔍 Recognize Chemical Formulas with Your Camera

Take a picture of a handwritten chemical formula, and the app will automatically attempt to recognize it using OCR (Optical Character Recognition) technology, without needing an internet connection.

🧪 Database of over 49 molecules

Explore a range of common chemical molecules, such as water (H₂O), methane (CH₄), ammonia (NH₃), carbon dioxide (CO₂), and more.

For each molecule, you can find:
• Number of electron regions
• Number of bonding pairs
• Number of free pairs
• Bond angles
• Electronic geometry
• Molecular shape
• Simplified information and explanations of how the shape is formed

🎨 Interactive 3D molecular models

View and interact with molecules in 3D models from all directions. Rotate the model and explore the arrangement of atoms, bonds, and the molecule's three-dimensional shape.

📐 Illustrative geometric diagrams

Easily understand molecular geometry through clear diagrams that illustrate the arrangement of electron regions, bonding pairs, free pairs, and the final shape of the molecule.

📚 Simplified Explanation in Arabic

Read an educational explanation for each molecule to understand the relationship between the number of electron regions, bonding pairs, lone pairs, electronic geometry, and the resulting molecular shape according to VSEPR theory.

🃏 Flashcards with QR Codes

Create printable flashcards on A4 paper. Each card contains a QR code that can be scanned to open the molecule directly within the app and view its 3D model.

A useful feature for teachers and students in classrooms and group review sessions.

🌍 Arabic, English, and French Support

Use the app in your preferred language, with a dedicated interface for each language.

🌙 Night and Day Modes

Choose the theme that suits you best, with support for both dark and light modes for comfortable study.

📴 Works Offline

The app is designed to work without an internet connection, including viewing molecules and using many of the device's recognition and processing functions.

🔒 Privacy First

The app does not require account creation and does not rely on collecting personal data to use its core functions. Processing takes place on your device wherever possible.


✦ For Students

• Learn molecular geometry in a visual and interactive way
• Understand the VSEPR theory of valence electron pair repulsion
• Learn about different molecular shapes
• Understand the role of bonding and free pairs
• Explore molecules using 3D models
• Learn about bond angles and electron geometry
• Use the app for review and test preparation

✦ For Teachers

• Use 3D molecular models to explain chemistry
• Visually demonstrate molecular geometry to students
• Create flashcards using QR codes
• Print the flashcards on A4 paper and use them in the classroom
• Make the lesson on molecular shapes and molecular geometry more interactive

✦ Supported Molecular Shapes

The app supports a range of basic shapes in VSEPR theory, including:

• Linear
• Crankshaft
• Planar triangular
• Triangular pyramidal
• Tetrahedra

The app also helps you connect electron geometry and molecular geometry based on the number of bonding and free pairs around the central atom.

✦ Learn Chemistry in a Different Way

Instead of just memorizing molecular shapes, explore why each molecule has a specific shape. Observe the arrangement of atoms in space and learn about the influence of free and bonding pairs on molecule shape and bond angles.

MolGeo is a suitable educational tool for studying chemistry, molecular engineering, VSEPR theory, molecular shapes, and 3D molecular models.
