The 9 best cloud storage apps for iOS and Android

It’s not an exaggeration to say that cloud storage apps have transformed the way we store and access files. Being able to access files anywhere, on any device, has become the norm at work and in our personal lives.

Virtually anyone can benefit from cloud storage apps, but they are particularly handy for remote workers and businesses that want to offer a BYOD policy, as Mindsight’s Siobhan Climer writes.

Be prepared to pay, however. Free solutions may be suitable if you’re using apps for basic storage, notes tech blogger Paul Mah, but the more advanced capabilities and increased storage required by most businesses are only available with paid solutions.

Want to get started with cloud storage apps but don’t know where to begin? Here’s our rundown of the best options.

Pro Tip

Collect file uploads online and send them to your cloud storage apps automatically with ready-made integrations from Jotform.

Google Drive comes preinstalled on the vast majority of Android phones and Chromebooks, making it the perfect choice for users who have already integrated part or all of their online lives into the Google ecosystem.

Google Drive doesn’t just sync your Google productivity suite files. It can also store all file formats, including PDFs, Microsoft documents, and photos. Apple users aren’t left out, either, as they can download Google Drive from the App Store.

4. iCloud

iCloud is Apple’s cloud storage platform. It comes preinstalled on all iPhones and is available for download in the Google Play Store. Android users will need to create an Apple ID to use the service if they don’t already have one, however.

6. Microsoft OneDrive

Microsoft OneDrive is the perfect cloud storage app for businesses and individuals who have already integrated their workflows into the Microsoft ecosystem. OneDrive is now part of Microsoft’s Windows 10 operating system, meaning if you have a Windows 10 device, then OneDrive is already installed.

OneDrive comes with 5 GB of cloud storage for free. A 100 GB version costs just $1.99 per month.

7. pCloud

pCloud offers free and secure multimedia cloud storage. What sets pCloud apart from most other providers is its no-knowledge local encryption service. This encrypts documents on individual devices to such a level that not even pCloud administrators can access them.

pCloud Mobile App

pCloud offers 10 GB of storage free. If you need more, the 500 GB Premium plan costs $47.88 per year, while the 2 TB Premium Plus plan costs $95.88 per year. pCloud also offers lifetime subscriptions for both paid plans for a one-time payment of $175 and $350 respectively.

Sync lets businesses share files with employees and clients instantly and securely. Access can be password-protected, and there are no limits on file size. You don’t even need to download a document to see a preview of it.

A free version of the app comes with 5 GB of storage. Pro plans start at $8 per month for single users or $5 per user, per month for a team account.

9. Tresorit

Tresorit offers a more secure alternative to some of the mainstream cloud storage apps on this list. In fact, privacy is the platform’s big selling point. Client-side encryption and secure data transfer mean your files are safe from prying eyes.

Tresorit Mobile App

There’s a 14-day free trial period, but users will need to pay to continue accessing the product afterward. The Premium package costs $12.50 per month and provides 500 GB of encrypted storage. The Solo package offers 2,500 GB of storage and costs $30 per month. Business plans start at 14.50 per user, per month billed annually with 1 TB of storage.

Remember, not every cloud storage app is equal. It’s important to identify the specific features you need and choose an appropriate app. If you need to access and edit articles on the move, for instance, choose an app that lets you make edits in the cloud, advises Business News Daily Editor. Some services require you to download files to make edits, which can be tricky on a smartphone.
