Citatum vs Math Surface

Your research deserves one clear home. Citatum turns scattered profiles into a focused view of your papers, citations, and progress across iPhone, iPad, and Mac. SEE WHAT IS MOVING Follow source-specific citations, h-index, i10-index, publications, and other available metrics. Citatum keeps every source separate, so each number keeps its meaning. BUILT FOR THE WORK • Browse, search, sort, and save papers in one library • See key metrics in Home Screen and Lock Screen widgets • Review snapshots and understand what changed • Receive alerts only for the sources and metrics you choose • Create polished Academic Cards and shareable research snapshots • Export JSON, Markdown, CSV, or BibTeX • Reach saved data with Siri, Shortcuts, and Spotlight No provider passwords. Add a public researcher profile and Citatum builds a record you can revisit offline. Supported data can stay in sync across your Apple devices through iCloud.

Provider availability and refresh timing depend on each public service. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

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.
