# Intro to Notifications

Critical Moments can send notifications to your users even when they are outside your app. These can help reduce churn, activate users, and improve conversion rate.

### How Critical Moments Enhances Notifications

Critical Moments offers several major improvements over typical push notification campaigns:

* **Smart delivery timing**:&#x20;
  * Deliver notifications when users are actively using their devices, appearing at the top to catch their attention. Your notifications are never buried under a pile of others.
  * Target the right users for each message by considering their engagement history and current state.
  * Wait for ideal engagement conditions, such as holding the device, on Wi-Fi, or not low on battery.
* **Amazing developer experience**: No push servers to manage. Easily deliver in user-local timezones.
* **Higher deliverability**: Notifications are scheduled locally on the device, ensuring they are delivered regardless of server and connectivity conditions.
* **Update anytime**: Update notification content and targeting anytime, without app updates or new coding. Growth teams can push content and targeting updates over the air, with only configuration updates.

Notification will only work if the user approves notifications for your app.

See the [Quick Start Guide](https://docs.criticalmoments.io/quick-start#request-notification-permissions) for instructions on how to request permission.
