Summary

As iOS has matured, a number of useful app-related settings and customization options have been introduced to the iPhone.
Aside from launching your installed apps, you can do such things as archive apps, switch out icon designs, and plenty more.
Here are some of the most useful things you might not know your iPhone can do with regard to its apps.

One of the primary components of the modern smartphone experience — whether we’re talking about iPhone, Android, or otherwise — is the great assortment of software applications waiting to be downloaded and installed.

Like most people, I spend a rather large chunk of time launching (and relaunching) apps on my own iPhone, each and every day of the week. Of course, apps are meant to be run, but the iPhone has a number of additional app-related tricks up its sleeve for managing these apps.

In fact, there are a whole host of useful app management utilities that Apple has built into the iPhone’s operating system over the years, many of which are hidden in plain site. Here are four of the most useful things that you might not know your iPhone can do with regard to its currently installed apps.

Best iPhone apps: The ultimate guide

We picked the best iPhone apps available right now, by category, from photo and video apps to the best social media apps and entertainment apps.

1 App offloading

App archiving has become a ubiquitous feature across most modern operating systems, and the iPhone’s iOS is no exception. Apple calls the feature App offloading, but it functions just as it does on competing platforms.

Offloaded an app will delete the parts of it that take up larger amounts of storage space, while preserving your documents and data in the process. When you want to use the app again, it’ll automatically re-download without forcing you to deal with any setup and login screens.

iPhone apps can be individually archived through the storage section of iOS, but there’s also a useful automatic mode that I recommend switching on. When enabled, lesser used apps are intelligently offloaded in the background.

To enable automatic app offloading, navigate to Settings > Apps > App Store > and toggle on Offload Unused Apps.

11 iPhone apps you can just go ahead and uninstall already

Your iPhone comes with nearly 50 pre-installed apps. Here are 11 that can go straight into the trash.

2 Require Face ID or Touch ID

Secure your sensitive data using biometric authentication

Every modern iPhone ships with either a Face ID (facial recognition) or a Touch ID (fingerprint recognition) biometric sensor. Aside from locking and unlocking your device itself, you can securely lock down access to parts of your iPhone on a per-app basis.

Apple has built two separate application securing options into iOS: require Face ID / Touch ID, as well as Hide and Require Face ID / Touch ID. The former simply forces a biometric verification prior to launching an app, while the latter obfuscates the app and places it in a hidden folder within the iPhone’s App Library panel.

To enable biometric authentication on a per-app basis, long press on your desired app > and then tap on Require Face ID / Touch ID. To require biometric ID while also hiding away an app, long press on an app > tap on Hide and Require Face ID / Touch ID > followed by Hide App.

3 Third-party icon packs

Though not natively supported, it’s still possible to customize the look and feel of your iPhone apps

Unfortunately, Apple has yet to open the floodgates and allow third-party app icons to display natively on the iPhone. I do expect this to change in the coming years, but for the time being, there is a viable workaround already in place.

By making some clever (and unintended) use of Apple’s own built-in Shortcuts app, you can manually add unique and creative icons onto your iPhone’s home screen. The process isn’t particularly difficult, but it’s admittedly a bit time-consuming. If you’re interested in checking out the steps involved, XDA has a dedicated tutorial published on its site.

Some developers and creative types have already built out collections of third-party icon packs, which are tailor-made for the iPhone. Some of my personal favorites include Vision iOS App Icons by Lokki, Leather Icons by Attiq ur Rehman, and Minimal Icons by Easlo.

4 Default apps

Starting with iOS 18.2, Apple provides a central location for configuring your favorite apps

The ability to swap out default apps has been an operating system mainstay for many years now, but it’s taken longer than expected for Apple to introduce the feature into the iPhone user experience. The concept is a simple one — if I want to switch from Safari to Chrome, I can tell the OS to respect this preference at a sytem level.

Mercifully, Apple has finally relented, and the tech giant now provides us with the option as of iOS 18.2. Currently, configurable options include email, messaging, calling, call filtering, browser app, passwords and codes, contactless app, and keyboards.

For iPhone users in the EU, this default apps page is even more flexible. As a result of the bloc’s Digital Markets Act (DMA), Apple provides additional default options such as App Installation, navigation, translation, and more.

To easily access the Default Apps screen on your iPhone, simply navigate to Settings > Apps > Default Apps.
