Notification system

A notification system is a way to remind people about important things. It can work through email, text message, or a specific app. For example, when you order something online you may get a notification when your order is shipped. It reminds you to check your mailbox so that you don't miss any packages. You can also set up notifications to get reminders about important events or appointments. For example, you could set up a notification to remind you to take your medication every day.
