Math Notes in iOS 26 have gained an extra dimension this year — literally. Yes, we can now create charts and graphs in three dimensions. (That was quite a good joke… anyway, moving on!)

You can now create 3D graphs in the Notes app simply by handwriting the equation you want to plot. Using the Markup tool, I’ll write:

z = x³ / y²

As soon as I finish writing, a pop-up appears because the iPhone has recognised this as an equation. And look — I’ve got the option to Insert 3D Graph.

When I do that, the graph appears in my note. I can move it around, resize it, and, best of all, explore the data in 3D by swiping my finger across it.

If I tap on the graph, a floating toolbar appears. The first option shows which equation is currently plotted (or multiple equations, if I’ve added more than one). The second lets me change the axes — repositioning where each axis begins and ends. I can even re-centre the graph if I need to.

And just like every other Math Note, I can model the data by tapping on any number in the original handwritten equation. Using the slider, I can move the value up or down — and the 3D graph updates instantly in real time.

This makes it possible to explore equations visually and interactively in a way that’s never been possible in Notes before.

It’s just one of the many new features in iOS 26 — some more useful, some more fun (like plotting 3D graphs!). Check out my channel down below to see everything else that’s new. I’ll see you next time.
