Push apps are mobile applications that deliver notifications directly to a user's device, even when the app isn't open. This is achieved through a system that uses push notification services, such as Firebase Cloud Messaging (FCM) for Android or Apple Push Notification service (APNs) for iOS.

How Push Apps Work

The core functionality relies on a server-client model. When a user installs the app, the app registers with a push notification service. This service acts as an intermediary between the app's server and the user's device. Whenever the app's server needs to send a notification, it sends the message to the push notification service, which then relays it to the user's device.

Benefits of Push Apps

Push notifications are a powerful way to engage users and increase app usage. By sending timely updates, special offers, or alerts, businesses can keep users informed and encourage them to interact with the app more frequently.

Examples of Push Apps

Numerous apps utilize this technology. Social media platforms use them to alert users of new messages or friend requests. Gaming apps might send notifications about events or updates. E-commerce apps keep users updated on order status or promotions.
