Elementum vs Reactix

Elementum is a beautifully simple way to explore the periodic table. Discover elements, understand their properties, and see how they come together, all through a clean, intuitive interface designed for clarity and focus. Explore Elements See all 118 elements in a full periodic table, or browse them block by block: s, p, d and f. Each block has its own colour, so you always know where an element belongs. Element of the Day Start each day with a new element. Elementum shows you what it is, why it matters, and exactly where it sits in the table. Understand Every Element Tap any element to see its atomic number, atomic mass, electron configuration, block, bonding type, phase, appearance, who discovered it, and a short description in plain language. Combine Elements Pick elements and compounds, set how many of each, and Elementum predicts the reaction: a balanced chemical equation and a one-line explanation of what happens. If two substances don't react, it tells you why. You can also build and save your own compounds. Private and On Device Reactions are predicted by a language model that runs entirely on your iPhone or iPad. Download it once and Combine works offline, and your experiments never leave your device. Find Anything Fast Search by name, symbol or atomic number and jump straight to the element you need. Made for iPhone and iPad On iPad, Elementum uses a sidebar layout, so you can browse the table and read about an element side by side. Elementum was made by a student developer and is a Swift Student Challenge 2025 winner. It's built for students, teachers and anyone curious about the building blocks of everything around us. Note: reaction predictions are generated by an on-device AI model and are meant for learning. Always check important results against your textbook or teacher.

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.
