# @ohos.reminderAgentManager (Agent-Powered Reminders)

The **reminderAgentManager** module provides APIs related to agent-powered reminders. When your application is frozen or exits, the timing and notification functions of your application will be taken over by a system service running in the background. You can use the APIs to create scheduled reminders for countdown timers, calendar events, and alarm clocks.

> **NOTE**
>
> The initial APIs of this module are supported since API version 9. Newly added APIs will be marked with a superscript to indicate their earliest API version.
