The Best Utility Apps for iPhone in 2026

Set up a new iPhone in 2026 and four utility apps belong on it before almost anything else: 1Password for your logins, Google Drive for your files, Speedtest for your connection, and ChatGPT for the writing and answers you did not know you needed on your phone. Each is fast, native-feeling on iOS, and earns its place on the home screen.

iOS gives you a solid baseline, but these four fill the gaps Apple leaves open. I have run all of them on iPhone long enough to trust them daily, and here is why they made the cut.

The best iPhone utilities at a glance

App	Best For	Platforms	Price	Rating
1Password	Secure logins and autofill	iOS, Android, Web, macOS	Subscription	9.0/10
ChatGPT	Writing and answers on the go	iOS, Android, Web	Free tier, optional Pro	9.1/10
Google Drive	Cloud storage and docs	iOS, Android, Web	Free tier, optional upgrade	8.6/10
Speedtest	Testing your connection	iOS, Android	Free	8.0/10

1Password — the first thing to install

On iPhone, 1Password plugs straight into the system autofill, so logging into apps and Safari is a single tap of Face ID. It stores passwords, passkeys, cards, and secure notes in one encrypted vault that syncs to your other devices. iOS has a built-in keychain, but 1Password is more capable, works everywhere including non-Apple platforms, and handles the whole family. It is the highest-value install you can make.

Best for: securing every login with instant Face ID autofill.

ChatGPT — a surprisingly good phone app

ChatGPT turns out to be excellent on iPhone. Voice input lets you ask a question hands-free and hear the answer back, which suits a phone far better than a keyboard. It drafts messages, summarizes long articles you paste in, and answers quick questions on the move. The free tier covers most needs; verify facts and keep sensitive data out, and it is one of the most useful apps on the device.

Best for: writing help and quick answers wherever you are.

Google Drive — your files, off the phone

Google Drive gives your iPhone real cloud storage with a generous free tier, plus Docs, Sheets, and Slides to actually work with those files. It backs up photos and documents, syncs across devices, and makes sharing simple. On a phone where local storage is finite and precious, offloading to Drive keeps things breathing.

Best for: storing files and editing documents without filling up your phone.

Speedtest — settle the "is it me or the Wi-Fi" question

Speedtest is the free diagnostic every iPhone should have. When a page hangs or a call drops, one tap tells you your real download, upload, and latency, so you know whether to blame the network or the app. It is genuinely free with no core features locked away, and it lives in the "glad I have it" category the moment your connection acts up.

Best for: quickly checking whether your connection is actually the problem.

Setting up a new iPhone with these

Install 1Password first and import or rebuild your logins — everything else gets easier once autofill works. Add Google Drive and back up your photos and documents so local storage stays free. Keep ChatGPT on the home screen for daily writing help, and tuck Speedtest into a utilities folder for the day the Wi-Fi misbehaves. Four apps, four gaps filled.

Freshness note: reviewed and updated in 2026 for current iOS versions and app releases.

Frequently asked questions

Do I need 1Password if iPhone has iCloud Keychain?

1Password is more capable, works across non-Apple platforms, and handles families and shared vaults. For many people it is worth the upgrade over the built-in keychain.

Is ChatGPT good on a phone specifically?

Yes. Voice input and quick answers suit the phone form factor especially well, and the app is fast and clean on iOS.

Will Google Drive free up space on my iPhone?

Yes. Backing up photos and files to Drive lets you keep less on the device itself.

Is Speedtest really free?

Yes, fully free with no meaningful paywall, and it runs a test in seconds.

Bottom line: on a fresh iPhone in 2026, install 1Password first, then Google Drive, ChatGPT, and Speedtest. Together they cover logins, files, writing, and diagnostics — the gaps iOS leaves open — and each feels right at home on the device.
