Push notification

Also called: Push alert, Web push

A push notification is a message that an app or website sends to your device through the operating system's or browser's push service, so it can appear even when the app isn't open.

How a push notification reaches you

  1. 1

    You grant permission

    The app or site asks to send notifications. If you allow it, your device registers with its push service and hands the app a token — an address for your device.

  2. 2

    Something happens

    Someone messages you, say. The app's server sends a short payload to the push service for your token: Firebase Cloud Messaging for Android, Apple's push service for iPhones, or the browser vendor's service for web push.

  3. 3

    The push service delivers it

    Your device keeps one efficient connection to its push service, so hundreds of apps don't each need their own. The notification arrives even when the app is closed.

  4. 4

    Your device shows it

    The operating system or browser decides how: banner, lock screen, sound or silent — shaped by your settings.

The push service only carries the message; the app decides what goes in it. Careful apps keep sensitive text out of the payload, and web push payloads are encrypted so that only the receiving browser can read them.

Getting fewer, better notifications

Notifications are one of the main levers apps use to drive engagement, so defaults tend to be generous. Rather than switching everything off and missing the one message that matters, turn off categories: keep messages and calls, mute likes and suggestions.

On Asyncbit

Asyncbit sends push notifications on Android and on the web (web push in your browser); there is no iOS app. You can switch categories on or off individually — messages, calls, likes, comments, follows, mentions, gamification, community and new content — or use a master switch. Message notifications stay generic (“New message”), so the text doesn't appear on your lock screen. Inside the app, notifications are grouped by category. See messaging for how chats and alerts fit together.
