# Notifications

[Notifications](https://developer.apple.com/design/human-interface-guidelines/ios/app-architecture/accessing-user-data/) can give people timely and important information, whether the device is locked or in use. For example, notifications can signal when a message arrives, an event is about to occur, or there’s a status change.

Here are the services that Natively uses to support the Push notifications feature:

[OneSignal](https://docs.buildnatively.com/natively-platform/features/notifications/onesignal-notifications)

[Firebase (Advanced)](https://docs.buildnatively.com/natively-platform/features/notifications/firebase-notifications-advanced)
