It's pretty amazing to think that Apple's mobile operating system is already nearly 10 years old, with the recently released iPhone 7£257.99 at Amazon UK shipping with iOS 10. The first iPhone couldn't even run third-party apps, if you can imagine that, but since then those apps have been paramount to the phone's success. There are now roughly 2 million apps available, ranging from the excellent to the awful.

New users of Apple's smartphone looking for a list of the first dozen third-party apps they need to install have come to the right place. The iPhone comes with many very capable and useful apps pre-installed, including ever-improving Maps, Messages, Music, News, and Photos apps. Be sure to take advantage of these built-in apps, as well as of the ever-smartening Siri voice assistant, the Find iPhone, and the Find Friends utilities. But do note that we don't include those in this roundup.

The apps on this list cover the basic functions most of us perform with our phones: communication, entertainment, and finding information, whether local or general. In addition to being among the most widely used and most useful examples of mobile software, most share another welcome attribute: All of them are free to use, though a few have optional subscription pricing for added functionality.

Of course, for each app included here, there are plenty of competitors, but those we include are the basics that everyone should at least know about and check out. For example, Jill loves fitness apps, and Michael is a photo-app aficionado, but we recognize that those genres are not everyone's cup of tea. In contrast, this list aims to hit the most important apps that are applicable to just about everybody. For a more-in-depth list of wonderful apps that may not be quite as universal, see our Top 100 iPhone Apps feature.

We also recognize that most iPhone owners want to play the occasional game, whether that's an intense car-racing title like Need for Speed or a cerebral word game like Words With Friends. But again, this list covers the basics. If you're looking for games specifically, check out our iPhone games roundup.

Below are the 12 apps we deem essential for most iPhone users. Don't agree with our picks? Let us know in the comments.

Evernote
Evernote

Evernote

Free
Without the Evernote app for iPhone, we'd be a lot less productive while we're away from our desks. This free, straightforward note-taking app outdoes the competition thanks to its strong search capabilities and effortless organization. But the real key to its success and popularity is that Evernote synchronizes all your files by saving them to a cloud service, meaning anything you create or alter on your iPhone will be there waiting for you when you log into any other version of Evernote.


Facebook
Facebook

Facebook
Free
The social network of record has come out with quite a few apps, but this one remains the most essential. If you watch strangers using their iPhones, there's a good chance that Facebook is the app they're using. And there's a reason for that: No other communication app offers the richness of interaction possibilities. (Of course, one of those communication types was stripped from the main app, and that's the next on in our list.) With the Facebook app, you can not only respond to friend's posts, but also upload photos, and even broadcast live video.


Flipboard
Flipboard

Flipboard

Free
Flipboard, an app initially designed for the iPad that curates content from your social networks and Web partners (think periodicals, blogs, etc.) based on your interests and turns them into stunning magazine-like digital pages, is now available on the iPhone. The app is free to download and requires a free user account. Flipboard absolutely shines on the iPad, taking advantage of swiping gestures with both visual and interactive grace, and it's still elegant on the iPhone, despite the smaller screen.


Gmail
Gmail

Gmail

Free
Google's main email app (the company also makes Inbox by Gmail) is a wonderful communication tool, as long as you only use Google's email service. Unlike our other Editors' Choice, Outlook, it doesn't handle mail accounts from any provider. But it does make your entire email database much faster and easier to deal with than the preinstalled Mail app can. That capability alone makes it a must-have iPhone app. It could very easily become your primary app for Gmail. It's smooth and fast, as well, but note that Apple doesn't allow third-party mail apps to become the default, the one that opens when you hit a link.


Google Maps
Google Maps

Google Maps

Free
Another one from the dominant force on the internet, Google Maps may well have the most up-to-date and detailed geographic information of any organization around. Its turn-by-turn directions by car, foot, and public transportation are hard to beat. With Google Maps, you can see estimated travel times and integration with your Google account for quick access to your home and work addresses. Offline maps, street view, and indoor maps are nifty plusses. After a shaky start, the iPhone's built-in Apple Maps now matches most of its features, however, and competitor Here Maps offers another good alternative.


Instagram
Instagram

Instagram

Free
Despite—or maybe because of—its limitations, Instagram has gone on to surpass Flickr as the number-one photo sharing service on the Internet. Its social discovery aspects are addictive, it offers excellent image-manipulation tools, and it now supports video, as well as still photos. The company keeps adding more features, like direct messaging, Snapchat-like Stories, and, finally, pinch-to-zoom. In keeping with the times and trends, the app now supports Handoff to switch between your Apple Watch and your iPhone.


Netflix
Netflix

Netflix

Free; $7.99 per month subscription
SEE IT
Netflix, like many of the other apps included here, has become a cultural phenomenon. Original, exclusive series, such as House of Cards and Stranger Things, are viewed by many as superior to much of what's available on broadcast or cable. Add to those the host of favorite standbys in both television and cinema releases, and you've got a must-have service. Note that this is one of the few apps included here that costs money, with subscriptions starting at $7.99.


Slacker Radio
Slacker Radio

Slacker Radio

Free; Optional subscriptions for ad-free and on-demand listening

Of all the music streaming apps in the Apple App Store, Slacker Radio's beats seem to pound the hardest. The same outstanding service you'll find in Slacker Radio's online version is on the iPhone and has been for a long enough time for the company to have massaged the interface and performance to the point that you can appreciate it audibly.


SnapChat
SnapChat

SnapChat

Free
Sexting and security worries aside, the visual chat app Snapchat can be a lot of fun to use—and let us emphasize "fun." Snapchat should not be used as a private and secure messaging app. Rather, it's a simple app that you can use to swap funny, ephemeral visuals with your friends. Messages sent through Snapchat disappear from the receiver's phone after a short time. The sender chooses up to 10 seconds as the limit. Snap a picture, draw or write on top of it if you like, choose the amount of time the recipient can see it, and send away. Just bear in mind that all digital media is reproducible, and that you should never send anything illicit, private, or anything meant to be secure through this entertainment app. Snapchat Stories last a bit longer—a whole day!


Twitter
Twitter

Twitter

Free
For a long time, Twitter Inc., the company that owns the 140-character social network, didn't make its own app. Dozens of third parties did, however, but not all the resulting apps were worth using. So when Twitter released its official Twitter app—and it worked well and loaded quickly!—users folded the new tool into their iPhones happily. If you tweet, it's a no-brainer to have this app. If you don't tweet and have been on the fence about joining the masses, the iPhone app makes it easy and convenient to get on board.


Weather Underground
Weather Underground

Weather Underground

Free
Sure, iOS has a Weather app, but you should forsake it because Weather Underground, our Editors' Choice for iPhone weather apps, is far better. It succeeds because it sticks to what it does best: clearly presenting lots of hyper-local information in a simple and highly customizable interface. The rich data in this excellent app will keep the most info-hungry meteorology geek satisfied.


Yelp
Yelp

Yelp

Free
The most comprehensive business-reviewing app, Yelp turns out to be an invaluable tool for finding restaurants, stores, and services nearby, especially when you're in a town you don't know well. Yelp's mobile app has helped Jill find a hairdresser when she was in a pinch in Washington D.C. and a suitable lunch while driving through Ohio. Michael finds the restaurant ratings consistently reliable. And you can find good local spots worldwide with it, not just in the US.

My Experience

I've been testing PC and mobile software for more than 20 years, focusing on photo and video editing, operating systems, and web browsers. Prior to my current role, I covered software and apps for ExtremeTech and headed up PCMag’s enterprise software team. I’ve attended trade shows for Microsoft, Google, and Apple and written about all of them and their products.

I still get a kick out of seeing what's new in video and photo editing software, and how operating systems change over time. I was privileged to byline the cover story of the last print issue of PC Magazine, the Windows 7 review, and I’ve witnessed every Microsoft misstep and win, up to the latest Windows 11.

I’m an avid bird photographer and traveler—I’ve been to 40 countries, many with great birds! Because I’m also a classical music fan and former performer, I’ve reviewed streaming services that emphasize classical music.

Technology I Use

For everyday work, I use a good-old Dell tower with 16GB of RAM, a 12th-gen Intel Core i7 processor, and an Nvidia RTX 3060 Ti GPU that runs on Windows 11. I pair it with a 4K Lenovo ThinkVision P27u-10 monitor and a Logitech MX Vertical mouse. For offsite work, I use a 2024 Microsoft Surface Laptop with a Qualcomm Snapdragon X Elite processor. Camera-wise, I moved to mirrorless from a Canon EOS 80D with a Canon 70-300mm IS USM lens. I now have a Canon EOS R7 with a 100-400mm lens, but I miss my DSLR for several reasons.

In order of usage, the software I turn to most frequently is the Edge web browser, Slack, Adobe Creative Cloud, Microsoft 365, Firefox, Brave, and WhatsApp. I use the Windows Phone link app to see everything on my Samsung Galaxy S21 Ultra phone, which has excellent telephoto capability.

For fitness monitoring, I have a Fitbit Charge 6 and use an Anker Smart Scale P1. I’m also a streaming fan, so I subscribe to both Amazon Music Unlimited (especially for its Dolby Atmos content) and Qobuz (for its high-res sound quality and classical catalog). I recently added a Vizio 5.1 Soundbar SE, which sounds surprisingly good given its low price. To holler commands instead of using a remote control, I have the Amazon Fire TV Cube in the living room, which lets me verbally tell the TV what I want to watch. It hooks up to an LG B4 OLED TV. I have a Sonos One speaker in my kitchen that also ties in with Alexa, as does the Echo Dot 2 With Clock in my bedroom. For serious listening, I have B&W 601 speakers plugged into a Conrad-Johnson Sonographe amp and preamp, with a Cambridge Audio AXN10 streamer as source. For reading, I also have a Nook GlowLight 3.

My Experience

I'm an expert in software and work-related issues, and I have been contributing to PCMag since 2011. I launched the column Get Organized in 2012 and ran it through 2024, offering advice on how to manage all the devices, apps, digital photos, email, and other technology that can make you feel overwhelmed. That column turned into the book Get Organized: How to Clean Up Your Messy Digital Life. I was also the first product reviewer at PCMag to test fitness gadgets, including everything from early Fitbits to smart bras.

Currently, I'm passionate about the meaning of work and work culture, and I enjoy writing about how managers and employees can communicate better, with or without software. My most recent book is The Everything Guide to Remote Work. I also love a good workplace drama. 

In addition to writing about work, I cover online education, focusing on learning for personal enrichment and skills development. I have a soft spot for really good language-learning software. Although I grew up speaking only English, some twists and turns in life led me to learn Spanish, Romanian, and a bit of American Sign Language. I've studied at the university level, as well as at the Foreign Service Institute, where US diplomats and ambassadors learn languages.

My writing has also appeared in WIRED, the BBC, Gloria, Refinery29, and Popular Science, among other publications.

The Technology I Use

Squeezing every last bit of usage out of the devices I already own is the only way I can tolerate my personal consumption. In other words, I do not own the latest cutting-edge technology. I buy things that will last and try to take care of them.

My life is organized by Todoist, and my notes live in Joplin. Where would I be without Dashlane as my password manager? Probably locked out of all my many online accounts—I have more than 1,000 of them.

When I share my contact information, it's an excruciatingly long list of phone numbers, messaging apps, and email addresses, because it's essential to stay flexible while also remaining somewhat mysterious.
