Intro to Numbers for iCloud
Numbers for iCloud is a web app for creating and editing spreadsheets on a Mac computer or Windows device (using a supported browser). Spreadsheets you create in Numbers for iCloud are automatically available in the Numbers app Account on any Mac, iPhone, or iPad where you’re signed in to the same Apple Account.
This integration across devices works in both directions. You can create or edit a Numbers spreadsheet anywhere—on a computer, iPhone, iPad, or on the web—and the changes show up everywhere. You can also share a link to a spreadsheet with others, then edit the spreadsheet together in real time.
After you sign in to iCloud.com (using the sign-in information for your Apple Account) and click Numbers, you see the spreadsheet manager. From here you can create, open, and share spreadsheets, and more.
