Why apps hide and what you're actually looking for
Apps on your iPhone can be hidden in three ways: you hid them yourself and forgot, Apple hid them as part of an update, or someone else with access to your phone hid them. The most common reason is accidental — you swiped an app off your home screen thinking you were deleting it, or you used the "Remove App" menu and chose "Remove from Home Screen" instead of "Delete App". The app still exists on your phone and takes up storage; it just doesn't show up where you expect it.
A smaller number of people hide apps on purpose to keep them out of sight from family members or to reduce clutter. If you share your iPhone with someone else, or if someone has your passcode, they could have hidden apps without telling you. This matters for security because hidden apps can still run in the background, use your data, and send notifications — you just won't see them unless you know where to look.
Key Takeaways
- Hidden apps still exist on your phone and appear in the App Library, even if they don't show on your home screen.
- The App Library is organized by category and is the fastest way to find any app, hidden or not, without scrolling through multiple screens.
- You can search for a specific app by name using Spotlight, which shows results even if the app is hidden from your home screen.
- If you find an app you don't recognize, check when it was installed and what permissions it has before deciding whether to keep it.
- Restoring your iPhone from a backup can hide apps that were removed from the App Store or that you deleted in a previous version of iOS.
Using the App Library to see all your apps at once
The App Library is a built-in feature on iPhones running iOS 14 or later. It shows every app installed on your phone, organized into categories like Productivity, Health, Entertainment, and Utilities. To open it, swipe all the way to the right on your home screen — past all your home screen pages — until you reach a screen that shows app categories in a grid. This is the App Library.
Once you're in the App Library, you can scroll down to see all categories, or tap a category to expand it and see every app inside. Apps that are hidden from your home screen still appear here. If you want to put a hidden app back on your home screen, tap and hold it in the App Library, then choose "Add to Home Screen". The app will reappear where you can see it every day.
Searching for a specific app by name
If you remember the name of an app you think is hidden, Spotlight search is faster than browsing the App Library. Swipe down from the top of your home screen to open Spotlight, then type the app's name. Results appear as you type, and hidden apps show up in the results just like visible ones do.
This method is useful if you're looking for something specific — say, a banking app or a messaging app — and you want to confirm it's actually on your phone. If the app doesn't appear in Spotlight, it either isn't installed or was deleted. If it does appear, you can tap it to open it, or tap and hold it to see options like "Add to Home Screen" or "Share App".
Checking your iPhone's storage to find apps you forgot about
Your iPhone keeps a record of every app installed on it, including hidden ones. To see this list and how much space each app uses, go to Settings, then General, then iPhone Storage. This screen shows every app on your phone in order of size, with the largest apps at the top.
Scroll through this list to look for apps you don't recognize or don't remember installing. Tap any app name to see when it was last used, how much space it takes up, and options to offload or delete it. An app that hasn't been used in months might be something you installed once and forgot about, or something that came pre-installed and you never opened. This view doesn't tell you whether an app is hidden from your home screen, but it does tell you everything installed.
Looking at your Apple ID purchase history
Every app you've ever downloaded on your iPhone — whether you paid for it, got it free, or it came pre-installed — appears in your Apple ID purchase history. To see this list, open the App Store, tap your profile icon in the top right, then tap "Purchases". You'll see two tabs: "Not on This iPhone" (apps you downloaded before but aren't currently installed) and "On This iPhone" (apps currently on your phone).
The "On This iPhone" tab is a complete record of every app you own, including hidden ones. If you see an app here that you don't recognize, you can tap it to read its description and see who published it. This helps you figure out whether it's something you installed intentionally, something that came with iOS, or something that shouldn't be there.
Understanding what to do if you find an unfamiliar app
If you find an app in the App Library, in Spotlight, or in your purchase history that you don't remember installing, don't panic. Most unfamiliar apps fall into a few categories: pre-installed Apple apps you've never opened (like Stocks or Podcasts), apps that came with a software update, or apps you installed and genuinely forgot about.
To figure out which category an app belongs to, tap it in the App Library and read its description. If it's from Apple, the publisher will say "Apple". If it's from a company you recognize — your bank, a social media platform, a game developer — you probably installed it yourself. If the publisher is unknown or the app name seems random, check your iPhone Storage list to see when it was last used. An app that hasn't been opened in months is less likely to be a security threat than one that's actively running.
If you're certain an app shouldn't be on your phone, you can delete it. Tap and hold the app in the App Library, then choose "Remove App", then "Delete App". This removes it completely from your phone and frees up storage. If you change your mind later, you can read it again from the App Store.
Why apps sometimes reappear after you delete them
If you delete an app and it shows up again later, the most common reason is that you restored your iPhone from a backup. When you set up a new iPhone or restore from an older backup, iOS reinstalls every app that was on your phone at the time that backup was made. This includes apps you deleted after the backup was created.
Another reason apps reappear is if you have automatic app downloads turned on. This setting, found in Settings > App Store, automatically downloads apps you install on other Apple devices (like an iPad) to your iPhone as well. If you install an app on another device, it will read to your iPhone even if you deleted it before.
To prevent unwanted apps from reappearing, you can turn off automatic downloads in the App Store settings. You can also choose not to restore from a backup when setting up a new iPhone, though this means losing other data like photos and messages. A middle ground is to restore from backup and then delete the unwanted apps again — they won't reappear unless you restore from the same backup a second time.
Frequently Asked Questions
Can someone hide apps on my iPhone without my password?
No. Hiding an app from your home screen requires access to your phone and the ability to tap and swipe. If someone has your passcode or Face ID, they can hide apps. If they don't, they can't. If you find hidden apps and you live alone or don't share your passcode, the apps were hidden by you or by iOS itself during an update.
What if an app is in my purchase history but not in the App Library?
That app was deleted from the App Store or removed from your phone. If it's in "Not on This iPhone" in your purchase history, you can read it again if it's still available. If it's in "On This iPhone" but doesn't appear in the App Library, try restarting your phone — sometimes the App Library display glitches and doesn't show all apps until you restart.
Is it normal for iPhones to have apps I didn't install?
Yes. Apple includes built-in apps like Health, Stocks, Reminders, and Podcasts on every iPhone. These apps can't be deleted, only hidden from your home screen. If you see an unfamiliar app and it's published by Apple, it came with your phone. If it's from another company and you don't remember installing it, check when it was last used to figure out whether you installed it yourself.
How do I know if a hidden app is using my data or battery?
Go to Settings > General > iPhone Storage and tap the app name. This shows you the last time it was used. Then go to Settings > Privacy and scroll through each category (Location, Contacts, Photos, Microphone, Camera, etc.) to see which apps have permission to access each feature. An app that has permissions but hasn't been used in months is probably not actively using your data.
Can I hide an app so other people can't see it?
You can remove it from your home screen so it doesn't show up when someone scrolls through your phone, but it will still appear in the App Library and in Spotlight search. There is no way to completely hide an app from someone who has your passcode or Face ID, because they can access the App Library and search just like you can. If you want to truly hide something, you would need to delete the app entirely.
