Learn English – Does ‘pinch’ have an opposite

antonymstechnology

Recently, I've found myself talking about the use of pinching to zoom out on mobile devices, and I've been struggling with an opposite for the word 'pinch'. In lieu of a better word, I've been saying 'unpinch'. I'm wondering if there's a more appropriate word to use to describe the motion of spreading the fingers from a pinch position.

In their own iOS Developer Library, Apple calls it pinching in and pinching out:

The pinch-in and pinch-out zoom gestures are standard gestures that iOS application users expect to use when zooming in and out.

Since Apple is the company that brought pinching to such widescale usage as it has been in recent years (and, as far as I am aware, though I have no sources to back this up, also the company that extended the meaning of pinch to include this thitherto unnamed touch-screen gesture), I’d say their terminology is more or less as definitive as you’re going to get in this particular context.
