Once you've found an app you'd like to have on your iOS device, the next step is to purchase it, if it's not a free app, and install it on your device. Whether an app costs money or whether it's free, the process for acquiring the app is the same. You can purchase and install either directly from your device, or from iTunes on your computer. Let's take a look at both ways starting with the iPhone. You can open up the App Store. And I'll just use the Near Me category for this, and here I'll tap the Hersheypark app. So again, on the details page, you can read about the app, see some screenshots, and read some reviews.
Also note at the bottom of the details page, you can see how large the app is, which is handy for seeing how much space it will take up on your device. Now, as of September 2013, any apps that are over 100 megabytes in size can't be downloaded without a Wi-Fi connection. This is up from the previous limit of 50 megabytes over a cellular connection. So, if you’re on an iPhone and your only current connection to the Internet is your cellular network and you try to download an app over 100MB. You’ll get a message saying that it’s not allowed and to connect to a Wi-Fi network, or to download the app through iTunes.
iPod Touch users won't see this message because Wi-Fi is the only way to get the iPod Touch online anyway. Speaking of the iPod Touch, be aware that some apps, especially those that take advantage of the iPhone's GPS capabilities, might not work with or be designed for the iPod Touch. Be sure to read the details of apps carefully to make sure they'll work with the Touch. If you have doubts contact the developer before spending money on an app you might not be able to use. But if you know the app will work, and it's under 100 megabytes if you're using an iPhone, scroll back up to the top, and the button here is either going to have a price in it if the app cost money, or it will say free as it does in this case.
Tap the button once, which turns it into an Install button. And that basically acts to confirm that you really meant to tap the button. So, tap Install. Next you'll be prompted to either enter your Apple ID and password, or just your password if you've already entered your Apple ID on your device. I'm just cancel that for a moment. And I'll show you where that setting is. You can go to Settings, iTunes and App Store and here at the top is where you enter your Apple ID. Now regardless of whether it's a free or a paid app, you have to enter your account info. First, this prevents unauthorized installations of apps on your device, and second it lets iTunes keep track of your purchases which, among other things, lets your re download and install them later in case you delete them, or if you lose your device and need to reinstall your apps on a new one.
If you have an iOS device with a fingerprint scanner, like the iPhone 5s, you can just use your fingerprint to make your purchase, instead of having to type in your password. But in this case, I do have to type in my password. And once you verify your info, your app should start downloading. If you leave the App Store, you'll see the icon for your new app appear on your device. And depending on the size of the app, and the speed of your Internet connection, it could take anywhere from a few seconds to several minutes for your download to complete. But once that Progress Dial disappears from the Apps Icon the program has been installed and you can run it immediately by tapping it. So, app purchases made from your iPhone, iPad, or iPod Touch are immediately installed.
Now, let's look at the purchasing and installation process from iTunes on your computer. All right, so here in iTunes, I'm in the App Store. And I found an app I'd like to install on my iPhone. This is an app called Star Chart, which is an app that shows you what constellations, stars, and planets you're looking at when you hold your device up to the night sky. This is also a free app. So here in iTunes, I just click where it says Free. And enter my password, it prompts it to do so. So I can see it's currently downloading. And once the download is complete, I'll find the app in the App section here in my iTunes library. This is where I'll find all the applications I've downloaded in iTunes.
But the Star Chart app hasn't yet been installed on my iPhone. To install it I'm going to select my iPhone which is currently connected to my computer. And then under Apps I'll find it listed here. Notice it's listed under iPhone iPod Touch and iPad Apps. So this is compatible with all three devices. Apps found under iPhone and iPod Touch apps will run on the iPad but they haven't been optimized for it in this case. So, it's here in the App Section where you can browse through all your apps here in this column, and then to the right, I have an exact representation of the current layout of my iPhone apps. To install the Start Chart app, I'll just click Install. Notice this has, Will Install, it hasn't yet installed it yet.
I have to first click Apply. Now, before I click Apply, I do want to point out that you can rearrange icons and screens here on iTunes if you want to. For instance, if I wanted that Start Chart app to appear here on the first page, I can simply double-click here on page two, that pops it out into the open, and I can just drag that over here to page one. Like so. You can also rearrange the order of the pages simply by dragging them side to side. Once you've clicked Install next to all the apps you want to install and you've arranged them as you like, click Apply. During the synch process any apps you installed directly from the App Store on your iPhone, iPad, or iPod Touch will be copied over into iTunes so you'll have them backed up there.
Now, if you ever want to uninstall an app, and you most likely will at some point because you're sure to run into some stinkers eventually, just find the screen the app is on, roll your mouse over the app, and then click its x button. When you next sync your device, that app will be removed, although it will remain in iTunes in case you ever do want to install it again by dragging it back in. The only apps you can't uninstall are the ones that come built into your device. So even if you never use say, the Stocks app, you're stuck with it. What you might want to do is drag all of your least used apps to the last screen of your phone, so they're not taking up space where you can place the apps you actually use.
So, I'll click Apply, it's telling me it's going to be removing that app from my phone, I say that's fine, And it's done. So back here on my iPhone, I can see the Star Chart app is exactly where I placed it here in iTunes. And if I go back to that last screen, you can see that Red Laser app has been deleted. Now you can also rearrange and uninstall apps from your device itself. To rearrange your apps, touch and hold down on any icon until they go into this sort of wiggly mode. This is your cue to just start dragging icons anywhere you like. You could even drag from one screen to the other. Remember that the bottom of the screen is for storing your four most used apps.
These icons stay visible no matter what screen you're on, so if you check your email all the time, for example, you'll want to make sure that mail stays in there. Maybe I use Twitter more than I use the Music app, so I'll just move the Music app, onto this screen, and move Twitter into my Dock. To delete an app, simply tap its x button. Again, I get this message telling me that deleting the app will delete all of its data. I'll tap Delete. And when you're done organizing and deleting your apps, just press the Home button, to leave that mode. Remember you can always re-install the app again from iTunes or through the App Store on your device.
Again, here on the iPhone I can go to the App Store, to the Updates tab, and here tap Purchase. This gives me a list of all the apps I've ever downloaded, and I can also use this just to see the apps that currently aren't installed on my phone. So if I previously deleted an app I can re-download it here. Just bear in mind that when you delete an app you'll most likely lose app specific preference settings. And again you can only delete the apps you downloaded and installed. The apps that come with iOS 7 can't be removed. Okay, so that's how you download and manage apps from the App Store.
