Its appeal lies in simplicity: no installation required, effortless sharing, an intuitive interface, and seamless reliability from a trusted brand.

It offers partial Microsoft Office compatibility, importing DOCX, XLSX, and PPTX files (though export is limited), plus advanced speech-to-text.

Apple's iWork suite (Pages, Numbers, Keynote) is typically $10 per app, but iWork for iCloud provides free web access—Apple's answer to Google Docs and Office Online.

Key strengths of iWork for iCloud:

• 5 GB free iCloud storage.
