DrPhos' Chemistry Pro brings a practical collection of general chemistry calculators together in one focused app.
Balance chemical equations and solve stoichiometry problems. Calculate kinetics and half-lives, solution concentrations, pH and buffers, molar mass, significant figures, quadratic equations, ionic compounds, and chemical names.
Included tools:
• Reaction Solver with balancing and stoichiometry
• Kinetics and half-life calculations
• Solution concentration calculations
• pH calculations, including buffers
• Molar mass and elemental analysis
• Scientific calculations and significant figures
• Quadratic equations
• Ionic compound building and chemical naming
Every tool is included with purchase. No account or internet connection is required, and the app works offline.
Clear inputs, validation messages, adjustable precision, formatted chemistry notation, and draft persistence help make calculations easier to enter and review.
DrPhos' Chemistry Pro is designed for chemistry education and study. It is not a substitute for professional laboratory, medical, or safety guidance. Follow your instructor's conventions and verify critical work independently.
This has helped me in my chemistry classes a lot! Definitely worth it and I highly recommend for students.
Great app!

Perfect for intro chem students!
This update improves the Science Calculator by preserving full internal precision across chained and follow-up calculations. Significant-figure settings now affect only the Normal and Scientific Notation displays, so rounded intermediate values cannot change later results.
