Curvely icon

Type an equation. Watch it draw.

This is the iPhone app, live. Try it.

Everything you need to read a curve

Several equations at once

Stack as many expressions as you like and give each its own colour, so relationships between curves are obvious.

Pan and zoom

Drag the plane and scroll to scale. The axes and gridlines relabel themselves as you go.

Native on iOS and macOS

A real SwiftUI app on Apple platforms, not a wrapped web page — built from the same maths as the web version.

Runs in the browser

Nothing to install and no account to make. Open the page and start plotting.

Readable in the dark

Light and dark themes that follow your system, with contrast tuned for long sessions.

Free and open source

No ads, no purchases, no tracking. The source is on GitHub.

Plot something

The web version runs straight in the browser — nothing to download.

Install it anywhere.

Curvely runs on every platform. On Windows, Linux and Android it installs straight from the browser — no store, no download, no runtime. It gets a real window, its own icon, and keeps working offline.
