Firebase In-App Messaging helps you engage your app's active users by sending them targeted, contextual messages that encourage them to use key app features. For example, you could send an in-app message to get users to subscribe, watch a video, complete a level, or buy an item. You can customize messages as cards, banners, modals, or images, and set up triggers so that they appear exactly when they'd benefit your users most.

Firebase Cloud Messaging (FCM) is a cross-platform messaging solution that lets you reliably send messages at no cost.
