 # Engage Project
-Push notifications are simple banner-like notifications that appear on your phone when your application sends a user a notification. Push notifications are an excellent way to re-engage users by notifying them of new updates and drawing them back into your application. This repository will allow you to create and test out push notifications using a Firebase server. Using React-Native, it will allow you to create a cross-compatible mobile application, both functional on iOS and Android operating systems.
