About this app

DrPhos' Chemistry Pro brings ten focused educational chemistry tools together in one private, offline app.

Balance reactions, work through stoichiometry, calculate pH and buffers, solve kinetics and solution-concentration problems, find molar mass and elemental composition, and convert between compound names and formulas. General calculator tools for scientific arithmetic, significant figures, and quadratic equations are included as well.

Included tools:

• Reaction Solver with equation balancing and stoichiometry
• Kinetics Calculator for zero-, first-, and second-order reactions
• Solution Concentrations for molarity, percent composition, and dilution
• pH Calculator for strong and weak solutions, conjugates, and buffers
• Molar Mass Calculator with elemental composition
• Science Calculator with significant-figure formatting
• Significant Figures analyzer
• Quadratic Solver
• Ionic Compound Builder
• Compound Naming for reviewed ionic and binary molecular compounds

Designed for learning:

• Clear equations, units, validation, and scientifically meaningful errors
• Chemistry-friendly numeric and formula entry
• Accessible controls, scalable text, native haptics, and responsive phone and tablet layouts
• All tools included with the paid app—no subscriptions or in-app purchases
• No account, advertising, analytics, tracking, or data collection
• Fully functional offline with no internet permission

DrPhos' Chemistry Pro is an educational tool. It is not a substitute for professional laboratory, engineering, medical, or safety guidance.

What’s new

Calculator follow-up and chained operations now preserve full internal precision. Significant-figure settings affect displayed formatting without changing later calculation results.
