About

SnackLab

Read full description

One app for the whole span of school and university math — from quadratics to Fourier series. Write an equation on the left and it is drawn immediately on the right. Tap an intersection, an extremum or an inflection point and SnackLab gives you the exact coordinates: a fraction, a root, a multiple of π — not a rounded decimal. WHAT YOU CAN GRAPH Functions Polynomial, rational, trigonometric, exponential and logarithmic curves. Piecewise definitions, asymptotes and removable discontinuities are handled properly. Calculus Derivatives, definite-integral regions, extrema and inflection points with exact coordinates. 3D Surfaces, planes and lines, the curves where they intersect, and closed regions. Rotate and pan freely. Statistics Distributions, interval estimates, data entry and charts. Differential equations Direction fields, numerical solutions, Laplace transforms. Keep several equations and switch between them. Engineering mathematics Matrices and eigenvalues, vector calculus, Fourier series, the complex plane. BUILT FOR EXPLORING Drag a slider and watch the curve respond — coefficients, parameters and domains update live. Save a graph straight to your photo library. The keyboard is laid out for mathematics, not for text: fractions, roots, exponents and Greek letters are one tap away, and the whole keyboard hides when you want the full screen for the graph. PRIVACY SnackLab collects nothing. No account, no sign-in, no analytics. Everything you type stays on your device. Available in English, Korean, Japanese, Chinese, Spanish, Portuguese, German, French, Indonesian and Vietnamese.
