TauerRush is a pocket mineralogy lab for anyone who sees chemistry in stones and beauty in formulas. With a clean dark interface, the app turns minerals, elements, crystal structures, and reactions into a clear and enjoyable learning experience. Explore a collection of 43 minerals across 9 families, from quartz and calcite to native gold, silver, and diamond. Each mineral has a detailed card with its chemical formula, Mohs hardness, crystal system, density, colors, formation conditions, practical uses, and surprising facts that make every sample feel more alive. The interactive periodic table includes all 118 chemical elements and helps connect each mineral to its real composition. Use pinch zoom, open individual element cards, and see how atoms become the building blocks of minerals found in nature. The Field Guide section offers 18 lessons on the basics of mineralogy, crystallography, and geochemistry, along with 12 step-by-step explanations of real scientific tasks. Learn how calcite reacts with hydrochloric acid, how pyrite oxidizes, how halite dissolves into ions, and how chemical equations can be balanced in a simple, understandable way. Quiz Lab helps test and strengthen your knowledge through 5 themed decks and 38 questions in different formats, including multiple choice, true or false, hardness ordering, formula matching, and reaction balancing. Best results are saved, so you can return, improve, and track your progress over time.
