App alerts are notifications sent by mobile applications to inform users about important updates or events. These alerts can include reminders, messages, or news updates, helping users stay engaged with the app. They can appear as banners, pop-ups, or sounds, depending on the app's settings and the user's preferences. Users can customize app alerts to control how and when they receive notifications. This feature allows individuals to prioritize which alerts are most important to them, reducing distractions while ensuring they don't miss critical information from their favorite applications, such as social media or calendar apps.
