## What is SnackLab?

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.

- Pinch with two fingers to zoom (zoom buttons removed)
- Parameter sliders appear right under the function that uses them

[Bug fixes]
- Fixed ODE graphs near singular points and in the phase plane
- Fixed cursor position when typing fractions and exponents
- Other minor fixes

### 1.1.8 — 2026-10-18

- Fixed solution curves breaking up where they rise steeply
