There are two types of mobile app notifications:


  • Remote Push notifications: These are messages sent from the cloud to a particular app on a particular device using either Firebase Cloud Messaging (FCM) or Apple Push Notifications Service (APNs) or both. Often companies will use intermediaries to send the push notifications out through FCM and APNs.
  • Local notifications: OpenBack doesn't use remote push notifications to send notifications, we believe that each install of your app should decide when a notification is shown to the user and as such we send all notifications to the user locally.  We call these Local Notifications. 


Remote and Local push notifications are identical from the users perspective.


The underlying technology and platform to provide local notifications, and make them flexible and easy to use for any mobile app is at the core of OpenBack's proprietary platform.
