MolSketchGo vs Spectromaster

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. Always verify results before research, teaching, publication, or any safety-related use. Japality Limited does not guarantee accuracy or completeness.

Spectromaster reads a spectrum from a photograph of a plot, or from an instrument's own data file, and helps you work out what your sample might be. Every measurement and every interpretation happens on the device in your hand. WHAT IT READS • ¹H and ¹³C NMR, from a photograph of a printed or on-screen plot • COSY, HSQC and HMBC correlation maps • JCAMP-DX (.jdx, .dx) and Bruker folders, at full instrument resolution • UV-Vis absorption and emission, IR, Raman and mass spectra • Boiling point, melting point, density, logP and optical rotation A vial collects every measurement of one solution — its ¹H spectrum, its IR bands, its melting point — and the app ranks reference compounds against all of them together. A compound consistent with three measurements is a far better hypothesis than one consistent with any single one. A ranked candidate list is a shortlist to check against your own data, not an identification. The reference library built into the app is small — 586 compounds. Type a SMILES string or draw a structure and get an estimated spectrum, drawn over the one you measured so you can compare them by eye. Estimates are labelled as estimates and never enter matching or scoring. No account, no login, no server, no analytics. All the reference data is compiled into the app. The only thing that can cross the network is your own records: switch on iCloud sync and your vials and their photos move between your own devices through your private iCloud database. It is off until you ask for it, we cannot read it, and the app is complete without it. FREE, AND PRO The free version keeps three solutions at a time. Pro removes the limit, and searches a shift table you supply — your group's own measurements — beside the shipped library. Reading, analysis, interpretation, refusals, export, backup and iCloud sync are identical in both versions and always will be. For laboratory interpretation by a trained operator. Not for diagnostic, forensic, safety, regulatory or GxP use. SUBSCRIPTION Spectromaster Pro — $2.99 per month, renewing automatically until cancelled. Your Apple Account is charged at confirmation and again each month unless you cancel at least 24 hours before the period ends. Manage or cancel in Settings › your name › Subscriptions.
