This is the biggest failure of Apple&#x27;s design on iOS and the article nails it perfectly.  It&#x27;s not <i>just</i> that you have to shake the device, it&#x27;s that you have to shake it and answer a modal and that all apps don&#x27;t treat it the same way.  You could be sitting there shaking your phone for 5 minutes wondering if you&#x27;re just shaking it wrong or if the app doesn&#x27;t offer an undo feature and there&#x27;s not really any way of knowing which is the right answer.
