Add and align text inside a shape in Keynote on iPhone

Go to the Keynote app on your iPhone.

Open a presentation, double-tap the shape to make the keyboard appear, then type your text.

If a clipping indicator appears, which signifies there’s too much text to display in the shape, tap the shape and drag any blue dot on the shape’s border until all the text is showing.

To align the text in the shape, tap the shape, tap , tap Text, then tap any alignment button.
