Alchemy-Pro Downloads & RevenueAlchemy-Pro: Chemistry Lab · App Store

Alchemy Pro turns your iPhone or iPad into a pocket chemistry lab: calculators that show their working, 3D structures you can rotate, spectra, and a virtual bench for experiments.

BUILT FOR
• Students checking homework and practising for exams
• Teachers who want a visual aid for the classroom
• Chemists and researchers who need quick data at the bench

CALCULATORS WITH WORKED SOLUTIONS
• Molecular mass with a breakdown per element — handles nested brackets such as Ca(OH)2 and K3[Fe(CN)6], and hydrates such as CuSO4·5H2O
• Mole calculator, equation balancer and stoichiometry
• Molarity, dilution, serial dilution and buffer recipes
• Acid–base titration curves and chemical equilibrium (ICE tables)
• Every answer shows the steps, so a wrong result becomes a chance to learn

3D STRUCTURES
• Molecules: load a compound from PubChem, a built-in VSEPR model or a file
• Lewis structures and VSEPR shapes for molecules and ions
• Crystals: 24 built-in structures with atoms per unit cell, coordination number, packing fraction, density, Miller planes and simulated powder XRD — plus 500,000+ measured structures from the Crystallography Open Database, or your own .cif file
• Proteins, DNA and RNA from the RCSB PDB, coloured by chain, secondary structure or N-to-C rainbow

SPECTROSCOPY AND XRD
• Mass-spec isotope patterns from any formula
• ¹H and ¹³C NMR and IR for 19 laboratory solvents
• Open real JCAMP-DX spectrum files
• Compare a measured XRD scan: peak finding, figure of merit, Scherrer crystallite size and refined lattice constants

VIRTUAL LAB
• Mix solutions, run flame tests, indicator and gas tests, build electrochemical cells
• Reaction-rate and burette-titration experiments
• Qualitative analysis for Groups I–V: add reagents, centrifuge, decant and follow the separation schemes
• A "name the mystery salt" game, a lab notebook for your observations, and your own custom reagents
• A PPE check (goggles, lab coat, gloves) before the bench unlocks

STUDY AND LAB REPORTS
• Practice quizzes generated from the app's own solvers
• 29 cited references, ready to copy into a lab report
• GHS safety classification and drug-likeness (Lipinski, Veber) on compound pages

HONEST ABOUT THE SCIENCE
Every result notes which numbers come from a model and which come from experiment, so students are never misled.

WORKS OFFLINE
Every structure you open is saved to your device, together with your search history. Export or import it as JSON.

LANGUAGES
The app interface is available in English and Thai.

DATA SOURCES
PubChem (NCBI), Crystallography Open Database, RCSB Protein Data Bank.
