MolSketchGo is a mobile tool for drawing and exploring chemical structures—for study and personal use. It is not intended for professional, safety-critical, or regulatory decisions. DRAW STRUCTURES • Tap to place atoms; drag between atoms to create bonds • Single, double, triple, wedge, and dash bonds • Long-press to move atoms; use two fingers to pan and zoom • Ring templates: benzene, cyclohexane, and cyclopentane • Skeletal mode, implicit hydrogens, and valence warnings when bonds exceed typical valence EXPLORE IN 3D • Generate a 3D view from your 2D sketch • Ball-and-stick, space-filling, and stick representations • Rotate and zoom IMPORT & EXPORT • Export PNG, SVG, SMILES, MOL, and SDF on device • InChI and IUPAC names require an internet connection via PubChem (NCBI) • Import SMILES and MOL/SDF files • Search PubChem by name, CID, or SMILES • Import PDB structures from RCSB for 3D viewing (3D viewer; not editable in 2D) MOLECULE INFO • Molecular formula, molecular weight, and DBE • Autosave drafts; dark mode and editor settings CHEMISTRY DATA DISCLAIMER Names, structures, and properties from this app or third-party sources (including PubChem) are provided for informational and educational purposes only.

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.

Verdict
The clearest difference is in-app purchases: MolViewApp at none against MolSketchGo's 2. MolViewApp also leads on ads (none vs shown) and update cadence (every 2 days vs every 2 months). MolSketchGo's advantage is iOS requirement (13.0 vs 15.0). On price and device support there is nothing between them.
