Magpie vs Gemology Notes

Magpie is a free molecular visualisation and scientific post-processing app for iPhone and iPad, designed for computational chemistry research, teaching and learning. KEY FEATURES • Open and inspect computational chemistry outputs, molecular coordinates, trajectories and volumetric data. • Explore interactive 3D structures, vibrational modes, reaction paths, spectra and potential-energy surfaces. • Export molecular structures and surfaces as GLB or USDZ 3D models, and trajectories, molecular vibrations and model rotation as USDZ 3D animations. • Edit atoms, bonds and geometries, then optimise structures with UFF or MMFF94s. • Generate quantum-chemistry input files, including ab initio molecular dynamics workflows, plus XYZ, MOL2, CIF and PDB files. • Load XYZ and DCD trajectories and visualise molecular orbitals, ESP and signed CUBE scalar fields. • Organise files locally, import from other apps, or connect to an authorised SSH/SFTP server for remote browsing, terminal work and optional Multiwfn-assisted analysis. • Visualise molecular orbitals and electrostatic potential (ESP)-coloured molecular surfaces from supported wavefunction files with one tap, with Multiwfn installed on your remote server.

Systematic Gemology Notes An offline reference app dedicated to gemology learning, covering the fundamental properties, crystal structures, and systematic classification of common gemstones. KEY FEATURES • Gemstone Browser — Reference material organized by crystal system and gemstone species • 3D Crystal Models — Interactive displays of each gemstone's crystal structure; rotate and zoom to examine every angle • Detailed Notes — Systematic knowledge covering physical properties, optical characteristics, and key identification points • Fully Offline — No internet connection required; study anywhere, anytime Ideal for gemology students, professional gemologists and appraisers, jewelers, and collectors.
