This is the iPhone app, live. Try it.
Stack as many expressions as you like and give each its own colour, so relationships between curves are obvious.
Drag the plane and scroll to scale. The axes and gridlines relabel themselves as you go.
A real SwiftUI app on Apple platforms, not a wrapped web page — built from the same maths as the web version.
Nothing to install and no account to make. Open the page and start plotting.
Light and dark themes that follow your system, with contrast tuned for long sessions.
No ads, no purchases, no tracking. The source is on GitHub.
The web version runs straight in the browser — nothing to download.
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.
Open the web app in Edge or Chrome, then Install Curvely from the address bar. It lands in the Start Menu like any other app.
Open & install →Open the web app in Chrome, then Add to Home screen. Full screen, no browser chrome, works offline.
Open & install →Same as Windows — install the web app from Chrome or Chromium and it runs in its own window.
