Molecule Geometry 3D vs MolViewApp

Molecule Geometry turns VSEPR practice into an interactive study tool. Rotate built-in molecules in 3D, or build your own from geometry templates by changing the central atom, ligands, and bond order with instant visual feedback. Study mode adds Quiz, Compare, and Guided Solver so you can practice instead of only browsing. Measure bond angles, show or hide dipoles, lone pairs, and bond types, inspect Lewis structures and resonance forms, and tap atoms to see the element name and formal charge. Save custom builds to your library, search by formula or name, and switch the interface language when you study. Great for class review, homework, and building intuition for geometry, polarity, hybridization, and electron-domain arrangement.

MolViewApp is an iPad molecular structure viewer built on Mol*. Load PDB files locally or by PDB ID and explore proteins with cartoon, surface, stick, and ball-and-stick representations. Features: - Load multiple structures; per-structure visibility from the Objects panel - Surface electrostatic potential map (screened-Coulomb / APBS-style) - Superposition and sequence-independent structural alignment - Secondary structure (DSSP) coloring - Morphing between conformations - Command-line interface and built-in manual All computation runs on-device. No account, no data collection, no tracking.
