MathFinder vs Math Surface

Now with Augmented Reality tools and overlays! This mobile app designed for children ages 8-16 allows you to discover math and science in real world places. You are immersed in a story line where you are an extraterrestrial investigating real world sites, gaining ranks and credits to advance on your mission. Watch videos by community members and STEM experts where you learn about how math and science appear in the world around you from the veins of a leaf to the design of a soccer field. Make your own observation and pose your own questions. Experience these locations virtually or use the app's geolocation features to engage in a scavenger hunt. This app was created by the nonprofit talkSTEM in partnership with Southern Methodist University's Guild Hall.

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.
