iOS 13

Let's say you're using your iPhone's Calculator app, and you're knee-deep into a complicated calculation with many steps. You type in a large number, for example, "123,466,789," but mess up. You meant to type "5" midway through but accidentally typed "6" instead. The only thing to do now is start over, no matter how far along you are, right? Wrong.

Your iPhone has hidden apps that work behind the scenes to filter SMS messages, trust computers, deal with payments, test ads, and perform other actions. You won't find any of them in your App Library, but there are tricks you can employ to unlock and use some of these secret apps.

Despite its name, the Frequently Used section on your iPhone's emoji keyboard features both frequently and recently used emoji, and it may contain emoji you've never even touched. If you want to remove all of those recommendations, there's an easy way to reset what you in Frequently Used to the defaults.

Almost 190 secret characters are hiding behind your iPhone's default keyboard, and I'm not talking about what you see after tapping the "123" or "#+=" keys. These special composite characters can include accents, dots, and other diacritics, and you'll even see some strange typographical characters like the section sign, inverted marks, and per mille symbol. Here's how you find them.

When you take a screenshot on your iPhone, it's automatically saved to your Photos app. You can ignore the screenshot thumbnail or swipe it away, but you shouldn't. If you open the screenshot editor instead, you'll gain access to your iPhone's most useful screen capture tool: full-page screenshots.

Speech-to-text technology can be seen on your iPhone in various places, from the Dictation tool to Apple's new behind-the-scenes, auto-created transcripts for podcast episodes. Your iPhone also has some pretty impressive text-to-speech capabilities. With them, your iPhone can read webpages, documents, or whatever text is on the screen out loud to you — only some of these tools aren't easy to find.

You may know the traditional way to take a screenshot on your iPhone, but it may not be the best action for your needs. There are faster ways to capture an image of your iPhone's screen, methods for capturing overlays and other elements that won't show in regular screenshots, and even options for blocking screenshot thumbnail previews from appearing.

If you want to try out one of Apple's beta programs on your iPhone — whether that's by becoming a developer, joining the public beta, or using an IPSW of an available beta update — there's always a possibility that you'll want to go back to the stable iOS version you were using before. Likewise, if you updated to the latest stable release but liked how iOS worked on the previous version.

Restoring your iPhone from a previous backup is still a simple process using your Mac, but the way it works has changed since Apple killed off iTunes with the macOS Catalina update. Now you must use Finder to both back up and restore your iPhone, which can take a little getting used to.

Emoji have taken over the world, so there's a good chance you regularly use (or overuse) emoji on your iPhone's keyboard just like everyone else. But before emoji were popular, there were emoticons, short for "emotion icons" — and iOS has a secret emoticon keyboard just waiting for you to unlock.

The screenshot tool on your iPhone can come in handy in various ways, but it may be even more helpful than you realize. So if you thought you knew everything there was to know about your iPhone's screenshot tool, it's time to put your knowledge to the test.

Ringtones and text tones can be annoying, so my iPhone is almost always set to vibrate on silent mode. Unfortunately, that causes me to miss phone calls and text messages when the device isn't in my hands or pockets. While I hate missing alerts, I'm still reluctant to switch to ring mode — and that's where another iOS and iPadOS feature helps out.

Apple has a secret iMessage effect so hidden that there's only one way to unlock it, and it's not by digging through the Messages app's settings, tools, effects, or interface. However, it's used the same way whether you're messaging from an iPhone, iPad, or Mac, so it's easy to remember once you know.

If you shoot videos with your iPhone in low-light situations, you may not always get the results you want. And that applies when recording video in 720p, 1080p, and even 4K resolutions. But there's an easy way to maximize your video's quality when filming in dark environments.

There's only one thing keeping hackers, thieves, law enforcement agencies, and maybe even the people you thought you could trust from breaking into your iPhone should they ever get possession of the device. Their odds of bypassing that thing are pretty good, but there's an easy way to make it an almost impossible feat.

There are many ways to open up the media account settings for your Apple ID on your iPhone, but they all require two or more steps. However, there is a hidden trick Apple hasn't told anybody about that can get there in one, and it's not Siri.

You may prefer reading news stories, web articles, and books on your iPhone over listening to them in spoken form. Still, sometimes it's necessary when driving, walking, cycling, cleaning, working, or performing other activities requiring a little multitasking. To help you out, Apple has a text-to-speech service on your iPhone — you just need to know how to find and set it up.

Without realizing it, you may be giving away the GPS coordinates of your home, workplace, school, and other important or secret locations. Unless you've blocked the feature on your iPhone, location data is stored in almost every photo and video you take, and anyone you share the content with can find out where you are or were. But there are a few things you can do to safeguard the information.

There's a whole world of hidden iPhone features you might be missing out on, but this little-known tool for iOS is something you should definitely enable so that it's ready when you need it.

Whenever you need to type out a fraction on your iPhone, whether in a message, word document, presentation, math problem, recipe, or wherever else you need it, it's easy to use numbers and slashes. But there's a way to make fractions look more professional and easier to read straight from your keyboard.

It's easy to accumulate hundreds of Safari tabs on your iPhone, which makes hunting for specific tabs more difficult, especially when they're spread across different groups. Having too many tabs can even slow down Safari itself. You can close all tabs in a group quickly, but not if you want to save some. To prevent this mess, Safari can automatically weed out the tabs it thinks you don't need.

Apple's Wallet app lets you store boarding passes, concert tickets, gym memberships, vaccination cards, movie stubs, rewards cards, insurance info, student IDs, and more in one place on your iPhone, and you just double-click the Home or Side button to access them. Unfortunately, many cards and passes are not officially supported — but that doesn't mean you can't add them.

A little-known setting on your iPhone gives you the power to change the color of certain contact names and email addresses when drafting an email. Customizing the color works well for visually separating contacts at a glance, and it can even help you from sending an email to the wrong person.

A low-key iPhone feature that's been around since iOS 10 can make the iMessages you send to family and friends more exciting overall. One particular element is, if you'll forgive my decades-old slang, "da bomb" for emoji.

While hitting snooze won't help you much if you fall back asleep, it can help you wake up more gently. However, your iPhone's default nine-minute snooze may be too long or too short for your preferences. If you tend to fall back asleep quickly, you might be better with a two-minute snooze.

Apple automatically converts most URLs in the Messages app into rich link previews, but they aren't always pretty, and sometimes you just want to see the full URL instead. While there is no setting on iOS, iPadOS, or macOS that disables rich link previews in the Messages app, there is an easy way to show the URL complete with the scheme, domain name, and path.

Automatic phone menus are the worst. You call the number, listen to prerecorded prompts, press button, listen, press button, listen, press button, listen, until you're routed or connected to the right extension, directory, menu, person, or whatever. But you can bypass these automated attendants to get right to where you need to go by setting up a simple shortcut on your iPhone.

You can set a GIF as the wallpaper for your iPhone's lock screen, but it won't animate like it does when looking at the image in the Photos app. It's an annoying limitation on iOS, but one that's easily bypassed with a tiny bit of work.

Remember when water and iPhones couldn't mix? Pools, tubs, and toilets would suck down the working iPhones of clumsy and careless owners and spit out expensive paperweights like they were nothing. Times have changed, however, and the newest iPhones can take a swim without fear of certain death. But a dip in liquid can still cause muffled music and audio from the speakers.

It's easy to start panicking when you delete an important email, but it's even easier to undo the mistake on your iPhone or iPad. You can retrieve an accidentally deleted email instantly on iOS and iPadOS with the help of a hidden gesture, and you'll be much more efficient with the Mail app once you learn how to use it.

You can take a photo on your iPhone with just one tap or press, but you can also use the Camera app hands-free for more impressive images. Doing so lets you take more detailed selfies, include your whole group in the frame, or get steadier results in Night mode — and it's easy to accomplish. Spoiler alert: using "Hey Siri" is not enough.

Whether you drop your iPhone into a toilet or your dog's water bowl or regularly take it into the shower or pool, water will likely become nestled inside its speaker grilles. Water exposure causes audio playback through the speakers to soften and sound muffled, and getting that water out is no easy task. Luckily, there's an app for that.

When you can't touch the shutter button on the screen in the Camera app, your iPhone has another way to snap a picture or take a video — just press the Volume Up or Volume Down button. But when it comes to bursts and QuickTakes, however, things are a little bit trickier in iOS 13, iOS 14, and iOS 15.

If you can't curb your TikTok obsession, at least make it more efficient by taking your hands out of the equation. So when you're eating breakfast, working on your computer, or using your hands for another non-TikTok task, you don't even have to touch your iPhone or iPad to scroll through all of those videos in your feed. Instead, you can just tell it what to do, and it'll listen.

A simple trick in the Messages app for iOS and iPadOS can make your iMessage conversations more fun for you and your recipients by sending a full-screen blast of any Memoji sticker you choose.

To the end user, mobile apps are sometimes expensive. To the developers, those costs are justified for all the hard work put into making the apps. Sometimes app creators will meet in the middle by putting their apps on sale or giving them away for a limited time to gain more traction in the App Store.
