GT Graph vs Materia

GT Graph transforms your device into a powerful mathematical visualization tool. Plot equations, explore calculus concepts, and bring mathematics to life with stunning interactive graphs. PLOT ANY EQUATION - Cartesian functions - Polar curves - Parametric equations - Implicit equations - Inequalities with shaded regions INTUITIVE INPUT Type equations naturally with implicit multiplication support. Write 2x instead of 2*x, or 2sin(x) instead of 2*sin(x). GT Graph understands mathematical notation the way you write it. COMPREHENSIVE FUNCTION LIBRARY - Trigonometric: sin, cos, tan, sec, csc, cot - Inverse trigonometric: asin, acos, atan - Hyperbolic: sinh, cosh, tanh - Exponential and logarithmic: exp, ln, log, log2 - Power functions: sqrt, cbrt, abs - Constants: pi, e, phi (golden ratio) MULTIPLE GRID TYPES - Standard Cartesian grid - Trigonometric grid with pi-labeled axes - Polar coordinate grid with radial lines - Logarithmic scale grid CALCULUS TOOLS - Calculate derivatives at any point - Compute definite integrals with visual shading - Find zeros (roots) of functions - Locate local minima and maxima - Generate value tables INTERACTIVE EXPLORATION - Pinch to zoom, drag to pan - Tap to show tangent lines - Crosshair cursor displays coordinates - Plot multiple equations simultaneously - Color-coded graphs for easy identification SAVE AND SHARE - Save your work as .gtgraph files - Export and share with colleagues - Equation history saves your last 25 entries - Settings persist between sessions Perfect for: - Students learning algebra, trigonometry, and calculus - Teachers creating visual demonstrations - Engineers and scientists visualizing data - Anyone curious about mathematical beauty GT Graph combines the power of professional graphing software with the elegance of modern design.

Materia brings the periodic table to life. Explore all 118 elements through a beautifully designed, interactive experience built for iPhone. Move beyond a traditional chart and discover the relationships, properties, and structure of the elements through multiple ways of exploring them. EXPLORE EVERY ELEMENT Browse the complete periodic table with accurate atomic numbers, symbols, categories, groups, periods, atomic masses, and carefully presented element information. THREE WAYS TO EXPLORE • Grid — Browse elements in a clean, visual collection. • Table — Explore the familiar periodic structure in a modern, interactive layout. • Orbit — Experience elements through an immersive spatial visualization with focus, relationships, and motion. DISCOVER CONNECTIONS Explore metals, nonmetals, noble gases, elements important to life, and meaningful compositions. Select an element to bring it into focus and discover related elements around it. DESIGNED TO FEEL ALIVE Materia uses subtle motion, depth, haptics, and responsive interactions to turn scientific information into something you can explore rather than simply read. MATERIA PRO Materia includes a useful free experience with the complete element library and core exploration tools. Materia Pro is an optional one-time purchase that unlocks the premium Orbit experience and advanced interactive visualizations. No ads. No subscription required for Materia Pro.
