# Push Notifications

Gravity comes bundled with everything you need to start sending push notifications - saving you hours of headache.

Users who sign into your app for the first time will be prompted to enable push notifications. If they accept, a push token is stored on the server for that user.

Gravity supports multiple devices per user.

## Sending Push Notifications

Please refer to the [Push Notifications section of the Gravity Server documentation](/gravity-server/push-notifications.md) to learn about sending push notifications from the server.

## Expo or Firebase?

Expo has a push notification service to send notifications immediately without any additional setup. However, you can also incorporate [Firebase](https://firebase.google.com) into your app and send push notifications with Firebase instead if you prefer.
