Math Surface vs Periodic Table Buddy

3D surfaces, 2D curves, the complex plane, probability — all in one app. Type a formula and watch it come alive. Perfect for study, exploration, or just enjoying the beauty of math. Description: MathSurface turns equations into shapes you can hold, spin, and slice. It's a math playground for iPhone and iPad — designed for students, curious minds, and anyone who learns better by seeing. ■ Features • 3D surface plots: visualize z = f(x, y) with smooth rotation and pinch-to-zoom • 2D function plots: explicit y = f(x) or implicit 0 = F(x, y) curves • Complex plane: loci such as |z − α| = r, arithmetic operations, powers, and n-th roots of unity • Probability distributions: binomial and normal, controlled by live sliders • Surface of revolution: spin any 2D curve around the x- or y-axis (rendered with SceneKit) • Cross sections: slice any 3D surface with a plane and see the resulting curve • Compare mode: overlay two functions in the same plot • Preset gallery: paraboloid, monkey saddle, Mexican hat, lemniscate, and many more • Favorites: save your own custom expressions for instant recall ■ Who it's for • High school and university students studying calculus, analysis, or probability • Teachers looking for live visual aids • Anyone curious about how a formula actually looks • People who just enjoy beautiful math A custom Liquid Glass–style formula keyboard makes entering sin, cos, √, π, and friends quick and natural. The dark neon UI keeps the math front and center.

Periodic Table Buddy is a chemistry learning app built around the periodic table, element facts, memory practice, quizzes, and visual explanations. Explore all 118 elements in an interactive table, then open rich element details with properties, common uses, chemistry facts, isotope notes, electron shell visuals, and reference links. Search by element name, symbol, or atomic number, and filter by category when you want to focus on a specific family of elements. The app is designed for students, teachers, tutors, and curious learners who want chemistry to feel easier to remember. Key features: Interactive periodic table with all 118 elements Element detail pages with properties, facts, uses, images, and reference links Flashcards for element recall practice Quizzes for testing chemistry knowledge Mnemonics and comic strips for remembering groups and periods Element comparison tools Browse mode for quick lookup Virtual lab simulations for simple reaction learning Local progress tracking without accounts, ads, analytics, subscriptions, or in-app purchases Periodic Table Buddy is educational software. Lab simulations and reaction notes are intended for learning and should not be used as real laboratory safety instructions. What's New: Initial release.
