Updating an App
App developers, including Apple itself, frequently release updates to the apps they sell (or give away). When you purchase an app, you are typically provided with free updates to the app. I say typically because some developers do release trial versions of their apps in addition to full versions; often times both the free trial versions and the full versions get updates, but not always. You might find yourself forced to purchase a full version for a specific update or feature, so just know that updates sometimes are only available after you purchase a full version of an app.
I already showed you how the App Store app displays a badge on the Update button to indicate the number of apps that have an update available. But what if you’re not running the App Store app? Well, in that instance, you need to keep an eye on the App Store app icon (see Figure 7.12). Even when the App Store app isn’t open, you still find that the updates badge pops up in the upper-right corner of the App Store app icon to alert you to updates.
Figure 7.12. The App Store app icon alerts you to updates.
If an update is indicated, tap the App Store app to open it and then tap the Updates button on the bottom toolbar (refer to Figure 7.5). You can also tap the Updates button any time you want to force the App Store app to check for updates.
When updates are available, they are listed as shown in Figure 7.13.

Tap the Update button to the right of any app to immediately begin updating that app, or tap the Update All button near the top-right corner and update them all at once. Keep in mind that updating a large number of apps at once can often take more than a few minutes. You’ll also be happy to know you can continue to work on your iPad—browse the internet, or maybe check email—while the updates install in the background.
