Reactix brings the chemistry lab to your pocket. Instead of just reading about reactions, perform them. Add chemicals step-by-step, observe real-time changes in color and temperature, and zoom into a molecular-level view to see exactly how atoms interact during a reaction. WHAT YOU CAN DO - Run guided experiments across categories like Neutralization, Single Displacement, Decomposition, and Combination - Follow clear step-by-step instructions for every experiment, from adding water to observing the final reaction - Switch to Microscopic Observation mode to see molecular behavior during the reaction, with plain-language explanations of what's happening and why - Get a full Lab Report after each experiment — including the balanced equation, reaction type, key observations, temperature change, and an accuracy score - Track every experiment you've completed in your Lab Journal, with dates and scores - Explore detailed chemical info cards — molar mass, pH, hazard level, and real-world uses for every substance - Use Quanta, the built-in calculator, for molarity, moles, dilutions, and unit conversions - no need for a separate app WHO IT'S FOR Whether you're a school student learning the basics, a college student who needs quick calculations, or just curious about how chemical reactions actually work - Reactix makes chemistry visual, hands-on, and easy to understand. WHY REACTIX Most learning apps only show text and diagrams. Reactix lets you perform experiments safely, at your own pace, and see the science happen - down to the molecular level - with no lab equipment or supervision required. Start experimenting. Start understanding chemistry the way it's meant to be learned.
