iDevice has a lot of accessibility options. Unlike a few other operating systems, iOS and OS X have a very specific focus on creating truly accessible devices and software. Naturally, the accessibility features of iOS (and OS X) are almost always very useful and practical.

One of the more common features required by a lot of people dealing with visual problems is “zoom.” You can zoom in/out of apps on the iPhone/iPad very easily with a three-finger double-tap.

Once you've enabled the zoom accessibility feature, you can now toggle zoom on/off on apps and other screens on the iPhone/iPad. Here's how to use it:

  • Double tap with three fingers anywhere on the screen to zoom in/out.
  • Drag three fingers to adjust to move around different parts of the screen.
  • Use one or two fingers to scroll in the particular part of the screen.
  • That’s it.

The Zoom feature works everywhere. It can be used to magnify icons on the homescreens, or used within apps to make text/images larger. The Zoom feature exclusively works with the triple-finger tap by default but you can actually change that.

For instance, if you want to enable Zoom with a HomeButton triple-click shortcut, all you do is:

  • Go to Settings → General → Accessibility
  • Tap on Accessibility Shortcut

You're done. You can now enable Zoom just by triple-clicking the home button.

One of the other things that you might want is Larger Text. If you're only looking to enlarge the font-size, here's what you should do.
