library of example graphs
tested to work in all modern browsers (Chrome recommended for best performance)
standard-compliant offline mode: visit our website once with a modern browser, use it again without being online
support for up to three parameters, customizable with sliders
can move the camera to a recommended position to have a good view on the curve

touch-friendly interface: every part of the UI can be used with touch
not limited to a special mobile platform, works on iOS, Android and WindowsPhone7
special enhancements for multi-touch navigation
special love for Safari on iOS
- workaround for a bug in Safari to enhance performance on iPad in landscape
- standalone mode: MathOverflow on your homescreen, with custom icons and splash screens, working online or offline

(mostly) self-explanatory icons, some of them custom-made for our UI (and in Retina resolution)
sliders disable if the parameter isn’t used
graphs get colored automatically when saved, so they can be distinguished
clicking on the camera icon, the camera moves smoothly to the recommended position instead of jumping there
controls can be hidden to have a clear view on the curve itself
help pages are displayed inline, so you don’t have to switch between this app and the pages
