9to5Mac has uncovered web-optimised versions of iOS Notes and Reminders in the service's latest beta build.
Notes enables users to compose and organise memos and send them out through the iCloud email, while Reminders alerts users about important dates and appointments.
The latest beta build of iCloud also includes the Lost Mode service, which will be a new feature of iOS 6. iPhone owners can use this to send out an alternate contact number to lost handsets to aid their safe return.
Apple is reportedly planning a major overhaul of its iTunes service with iCloud more deeply integrated to help users organise and share their content with greater ease.
The new iCloud web apps are expected to be introduced when iOS 6 launches in the autumn.
