In previous versions of the iOS, there wasn’t an application for reminders. This created many to do list type applications. With iOS 6, we now have a reminder application that will sync through the iCloud to your other devices.
This is a reasonably simple reminder application. It does allow you to create groups of reminders, called lists. It also allows you to set dates and times for your reminder, and to add extra notes. Because of its connection to iCloud, reminders written on one device, automatically appear on the other devices.
