Q: I'm not planning to pair my iPhone or iPad with the new AppleWatch, but yet an AppleWatch app has appeared on my device. Can I delete the icon since it's just taking up screen space?
A: Periodically, the Apple device's Settings app will notify you that there is a system software update available, and most of us dutifully install it onto our phones or tablets. The latest iOS 8.2 update placed a new AppleWatch app on our devices.
The short answer to removal ability is 'no', unless you 'jailbreak' your iDevice by using hardware and software exploits to get around Apple's restrictions--something that most of us non-geeks won't be attempting. Therefore, this might be a good time to look at some app management methods instead.
If you press and hold your finger down on any app, you'll note that all of the icons will start jiggling so that you are in a mode where you can move those icons around on the screen or even over to the new screen to your right or left. This lets you arrange the icons in any organizational manner that makes sense to you.
There is a dock (see screenshot #1) on the bottom of your device where you can place a small number of apps that you use frequently, so that you can access those icons quickly, no matter which screen you happen to be on.
Notice that some icons have a little 'x' in the upper left hand corner while others do not (screenshot #2 shows that Apple's Facetime videoconferencing app does not have the 'x' but the Twitter app does). Icons which have an 'x' represent apps that you've chosen to download from the AppStore, and you can delete them by simply tapping the 'x'.
The icons which don't display an 'x' are Apple iOS system or 'core' apps which have special programming permissions, and these apps aren't available to switch in and out of the AppStore. Instead, this operating software is 'hardwired' into your device ecosystem, such as your phone/voicemail, camera, email, calendar, address book, and messaging/texting functions. Utilities like a calculator, clock, and compass fall into the core app category, as well as Apple's own software such as iTunes, weather, stocks, maps, music/podcast players, iBooks/Newsstand viewers, and internet web browser (Safari). Recent additions to Apple's core app lineup include Passbook (for those of you who are starting to use 'tap and pay'), Health (monitoring), and now AppleWatch.
With so many core apps floating around on our screens, we are bound to find some of them not useful, but since we can't delete them, a workaround may be to 'bury them' inside a folder to your farthest screen (you can tell which screen you are on by the dot position of your screen row (screenshot #3).
In order to create a folder containing two or more app icons, you hold your finger down on any app to enter that 'jiggly' mode, and then move/place the icon for an app that you'd like to hide directly over a second icon that you'd also like to hide in the same folder.
A white border will appear and when you release your finger, a 'folder' will have been created, and the two icons you've maneuvered are now consolidated into that folder. Once you've created the folder, you can now start moving other jiggling icons into that folder.
You can change the name of that folder from whatever Apple suggested, by tapping the 'x' next to the folder name while you are in the 'jiggly' mode, and typing in a new folder title. As you can see in screenshot #4, I've banished quite a number of apps to a folder named 'Siberia' over to my last screen, where I will rarely see it.
For those of you who have a lot of app icons or even numerous folders because you like to bundle similar apps together, a quick way of finding an icon is to place your finger on the screen and pull down, revealing the Spotlight Search bar. In this field, you can type in the same of the app you're searching for, and even if it's only a fragment of that name, Spotlight Search should be able to display all your app or file names that contain your requested phrase, much like the Google bar for web searches.
