iCloud review: our verdict

This iCloud review looks at Apple's cloud service, including iCloud Drive and the paid iCloud+ storage plans, and asks who it really serves. The short answer: if your phone, tablet and computer are Apple devices, iCloud is the most convenient cloud storage you can use, because it is built into the operating system and keeps photos, files, backups, passwords and app data in step without any setup. It also offers one of the strongest optional encryption settings in mainstream cloud storage, Advanced Data Protection.

The trade-offs are just as clear. iCloud works poorly outside Apple's world: there is a Windows app but no Android app, sharing with people who do not use Apple products is clumsy, and power-user features such as flexible folder sync are thin. That is why we rank it as the best choice for Apple users rather than the best cloud storage for everyone.

NerdBible did not run its own hands-on trial for this review. It is an editorial assessment based on Apple's own support and product pages and on the published findings of independent outlets, which we credit and link below.

What is iCloud and who is it for?

iCloud is Apple's sync and storage service. According to Apple's iCloud+ page, it covers iCloud Photos, iCloud Drive, iCloud Backup for iPhone and iPad, Mail, Notes, Calendar, Contacts, Safari bookmarks, Passwords and Keychain, and Messages in iCloud. iCloud Drive is the part that behaves like a conventional cloud folder: on a Mac it appears in the Finder, on an iPhone or iPad in the Files app, and on a PC through the iCloud for Windows app or in any browser at iCloud.com.

It suits:

  • Households that use iPhones, iPads and Macs. Everything syncs without extra apps, and one paid plan can be shared with up to five family members.
  • People who mainly want their phone backed up. iCloud Backup runs automatically when an iPhone or iPad is charging on Wi-Fi, and restoring to a new device brings apps, settings and data back.
  • Privacy-minded Apple users. iCloud+ adds Private Relay and Hide My Email, and Advanced Data Protection extends end-to-end encryption to most iCloud data.

It is a poor fit for people who use Android phones, for teams that share files with many outside contacts, and for anyone who wants granular control over which folders on a computer sync.

Key features

Photos and device backup

iCloud Photos stores full-resolution photos and videos in the cloud and can keep space-saving versions on each device. Shared Albums and the Shared Photo Library let families pool pictures, and Apple says Shared Albums can include people on Android or Windows. For many Apple users, photos and device backups are what fill their storage, and iCloud handles both with no setup beyond switching them on.

iCloud Drive

iCloud Drive stores files and folders and makes them available on every signed-in device. Mac users can choose to sync their Desktop and Documents folders. Apple also lists link-based sharing and live collaboration in Pages, Numbers and Keynote, with control over who can view or edit.

iCloud+ privacy features

Every paid plan includes iCloud Private Relay, which hides your IP address and browsing from network providers when you use Safari; Hide My Email, which creates random forwarding addresses; a custom email domain for iCloud Mail; Apple Invites; and HomeKit Secure Video recording, with the number of supported cameras rising with the plan, according to Apple's iCloud+ plans page.

Windows and web access

Apple's iCloud for Windows download page says the app, installed from the Microsoft Store, gives a PC access to photos, videos, mail, calendar and files, and that the latest version needs Windows 11 or later. iCloud.com works in most browsers. There is no Android app.

How much does iCloud cost?

Our page shows current prices from our own data, so we describe the structure only. Apple's plans page says everyone gets a small free allowance, 5 GB, shared across backups, photos, mail and files. Above that, iCloud+ comes in several storage tiers, from an entry plan for light users up to very large multi-terabyte tiers for photographers and families. Plans are billed monthly, there is no annual discount, and every iCloud+ plan can be shared with up to five other family members at no extra cost. Apple also bundles iCloud+ storage into its Apple One subscriptions.

Two practical points: the free 5 GB fills quickly once photos and phone backups are switched on, which is why most iPhone owners end up on a paid tier; and prices vary by country, so check the figure in your own region.

Is iCloud safe and private?

Apple's iCloud data security overview describes two settings. Under standard data protection, the default, your data is encrypted in transit and at rest, but Apple holds the keys for most categories so that it can help you recover your account. Fifteen categories, including Health data and passwords in iCloud Keychain, are end-to-end encrypted even under the default setting.

Advanced Data Protection is an optional switch that raises the number of end-to-end encrypted categories to twenty-five, adding iCloud Backup, iCloud Drive, Photos, Notes and more. Apple's guide to turning on Advanced Data Protection spells out the responsibilities: you must set up a recovery contact or recovery key, Apple cannot recover that data for you if you lose access, web access at iCloud.com is turned off by default, and content shared through iWork collaboration, Shared Albums or open sharing to anyone with the link is not end-to-end encrypted. Mail, Contacts and Calendars are not end-to-end encrypted under either setting because of the open standards they rely on.

There is one important regional exception. Apple has published a notice that it can no longer offer Advanced Data Protection to new users in the United Kingdom. UK users who had not already turned it on cannot do so, and their backups, Drive files and photos stay under standard protection. Apple says the feature remains available everywhere else.

What could be better

  • No Android app. Android users are limited to the web, so automatic photo backup from an Android phone is not possible.
  • Clumsy sharing outside Apple. Several reviewers found that recipients often need an Apple Account to open shared files, and that link controls are limited.
  • Basic sync controls. You cannot pick arbitrary folders to sync as you can with some rivals.
  • Small free tier. 5 GB covers little once backups and photos are on.
  • Regional limits. Advanced Data Protection is not available to new users in the UK.

Who should choose something else?

If you use an Android phone, or your household mixes platforms, Google Drive or Microsoft OneDrive will serve you better. If you mainly need to share large files with clients, a service with stronger link controls, such as password-protected links, is a better tool. If zero-knowledge encryption across all your files is the priority, especially in the UK, a dedicated private storage service such as Sync.com is worth comparing. And if you need cheap bulk storage for archives rather than syncing, specialist backup services can cost less per terabyte.

Is iCloud worth it? Bottom line

For anyone living in Apple's ecosystem, iCloud is close to essential: it is the only service that syncs the Photos app, device backups and Apple's own apps natively, and iCloud+ adds genuinely useful privacy tools. Turn on Advanced Data Protection if it is available to you and you are comfortable managing your own recovery key or contact. If your devices or the people you share with are not all on Apple, pair it with, or choose, a cross-platform service instead.

What other reviewers found

  • PCMag called iCloud Drive the simplest sync tool for Apple devices and praised its security extras, but said its sharing requirements limit its appeal and rated Microsoft OneDrive a better pick for most people.
  • TechRadar said the service has improved a lot and integrates deeply with macOS and iOS, but remains only really useful on Apple hardware, with no Android support.
  • Tom's Guide found syncing seamless for Apple users but judged the plans generally more expensive than some rivals and criticised sharing links that expire and cannot be password protected.
  • Cloudwards described iCloud Drive as a bare-bones sync folder with "incredibly disappointing" speeds in its own measurements, though it considered the prices competitive.
  • Macworld recommended it to Mac users already paying for iCloud, while noting that it syncs rather than backs up and that sharing with people on other office suites adds friction.

Where they agree: every outlet agrees that iCloud is the most seamless choice inside Apple's ecosystem and a weak one outside it, and that sharing with non-Apple users is the main pain point. Where they differ: on value, Tom's Guide considers iCloud expensive while Cloudwards calls its prices among the better ones; PCMag finds sharing barely works without an Apple Account, while Apple's own documentation describes sharing open to anyone with the link. Reviewers also simplify the encryption story; Apple's security overview is the most precise guide. For a buyer, that means the decision rests mostly on what devices you and the people you share with use, not on price or speed.

Frequently asked questions

How much free iCloud storage do you get?

Apple gives every Apple Account 5 GB of free iCloud storage. That space is shared across iCloud Backup, iCloud Photos, iCloud Drive, Mail and app data, so it fills quickly once photo sync and phone backups are switched on. Upgrading to any iCloud+ plan adds more storage and the privacy features, and a paid plan can be shared with up to five family members.

Is iCloud end-to-end encrypted?

Partly by default and mostly with an optional setting. Under standard data protection, fifteen categories such as Health and Keychain passwords are end-to-end encrypted, but Apple holds the keys for others, including backups and photos. Turning on Advanced Data Protection extends end-to-end encryption to twenty-five categories, though Mail, Contacts and Calendars stay outside it.

Can I use iCloud on Android or Windows?

On Windows, yes: Apple's iCloud for Windows app from the Microsoft Store syncs photos, files, mail and calendars, and the current version needs Windows 11 or later. On Android there is no app, so you are limited to iCloud.com in a browser. That means no automatic photo backup from an Android phone, which is why mixed households often prefer a cross-platform service.

Why can't I turn on Advanced Data Protection in the UK?

Apple has said it can no longer offer Advanced Data Protection to new users in the United Kingdom. UK users who had not already enabled it cannot switch it on, so their backups, iCloud Drive files and photos remain under standard data protection. Apple says the fifteen default end-to-end encrypted categories, and iMessage and FaceTime encryption, are unaffected.

Is iCloud a backup or just sync?

Both, in different places. iCloud Backup makes automatic backups of an iPhone or iPad. iCloud Drive and iCloud Photos, however, are sync services, so deleting a file or photo on one device removes it from your other devices too. If you want an independent copy of your Mac or your files, keep a separate backup alongside iCloud.
