See the shape of a function. Plot up to six curves together, with independent colors, visibility, and parameters. Choose standard forms for linear, quadratic, power, root, reciprocal, exponential, logarithmic, trigonometric, and absolute-value functions. Explore changes with parameter sliders and numeric controls. Switch between radians and degrees, pan and pinch to zoom, or hold to read coordinates on the selected curve. Save pages, favorite graph collections, and restore your 50 most recent pages. Export PNG images with axes, colored curves, and formula legends using the system share sheet. Wide iPad windows offer a collapsible function sidebar. Phones and narrow windows use a bottom panel. Light and dark appearance, larger text, and reduced motion are supported. Choose the interface language, system, serif or monospaced fonts, and text size (80%–200%) in Settings, or follow system preferences. Supported languages: Simplified Chinese, English (US and UK), French, German, Spanish, Portuguese (Brazilian wording), Japanese, Korean, Vietnamese, and Arabic. Arabic uses a right-to-left interface while mathematical expressions remain left-to-right. No account required. Plotting and page storage work offline. One purchase unlocks the current complete app, with no advertising, subscription, or in-app purchases. Privacy and support websites require internet access. Implicit equations, parametric and polar plots, and symbolic calculus are not included.
