IPad

The iPad, iPhone and iPod Touch form Apple's range of mobile devices. They all use Apple's iOS operating system and share a common user interface.

Apps become unresponsive

 * Close the unresponsive app fully by pressing the Home button once to return you to the main screen, then twice more to bring up the list of active apps at the bottom of the screen. Press on the icon of the errant app and hold until the icons begin shaking on-screen. A delete icon (white circle with a minus symbol against a red background) will appear on top of all running app icons. To fully close the application touch the delete symbol.
 * If closing an individual app doesn't work turn the iPad off and back on again. Hold the power button on the top-right edge until "slide to power off" appears on-screen, then power it off.

Device becomes slow, unresponsive

 * Turn the iPad off and back on again. Hold the power button on the top-right edge until "slide to power off" appears on-screen, then power it off. Cycling the power off and then back on every few days generally keeps iPads, iPods and iPhones running at their best.
