Access Your App-Specific Data Online at iCloud.com
Another benefit of using iCloud to sync your app-specific data is that using any computer or Internet-enabled devices, you can visit www.iCloud.com, log into this website using your iCloud username and password (which is typically your Apple ID username and password) and then access online-based versions of the Contacts, Calendar, Reminders, and Notes apps. (This is shown on a Mac using the Safari web browser in shown in Figure 6.5). Your most up-to-date data from these apps appears within the online versions of the apps.
So, if you forget your iPhone at home, for example, you can still access your complete Contacts database, your schedule, your to-do lists and your notes from any computer.
Once you log into iCloud.com, click on the on-screen app you want to access. The online apps are almost identical to the iPad versions of the Contacts, Calendar, Reminders, and Notes app.
