In-Depth Information
It's sometimes difficult to get a sense of what an app offers by looking
solely at screenshots, so be sure to tap the link that takes you to a
developer's Web site for more information. Often companies will include video
of how the app operates.
If you decide your life isn't complete without the app, tap the button that
displays the price. The button changes to read “Buy App”; if the app is
free, you'll see “Install App” (
Figure 2.2
). Tap it again to purchase, or tap
anywhere outside the button to switch back to the price.

the Buy App button.
After you enter your iTunes Store account password, the app downloads
and is installed in the first open space on the Home screen (

).

note
If you're connected to the Internet using 3G, large apps—over 20 MB—
won't be downloaded. Connect to a Wi-Fi network or use iTunes on
your computer and try the purchase again.
The iTunes Store knows which apps you've purchased on other
devices. Those appear with an Install button; no need to re-buy them.
