What is iCloud Reminders?
You can create and manage to-do items and organise them into lists using Reminders on iCloud.com. You can also share reminder lists with other iCloud users.
Changes you make to reminders and reminder lists on iCloud.com automatically appear on your iPhone, iPad, iPod touch and Mac when those devices have iCloud Reminders turned on. If you are not using upgraded reminders, you can also see your reminders on a Windows computer if Tasks is turned on. See What can you do with iCloud on a Windows computer?.
Reminders also appear in Notification Centre on your iPhone, iPad, iPod touch and Mac.
To use iCloud Reminders, go to icloud.com/reminders and sign in with your Apple ID. Make sure you use a browser recommended in the Apple Support article System requirements for iCloud.
If you do not see Reminders on iCloud.com, your account is limited to iCloud web-only features. To gain access to iCloud Reminders and other iCloud features, set up iCloud on your iPhone, iPad, iPod touch or Mac.
If you are using another feature on iCloud.com, you can switch to Reminders by clicking the feature’s name in the top left-hand corner of the iCloud.com window.
Note: If you have upgraded your iCloud Reminders account, you can see your reminders on iCloud.com and on any device with iOS 13, iPadOS 13, macOS 10.15 or later.
