Use a “pop” animation style when badge numbers increase.
Known or unknown number:
To keep in mind
We want to draw attention to a specific value
The badge text can be a number or a number with text like “10x” for a multiplier
When to use
Use badges for counts of important information, close to the relevant item.
A dot badge notifies the user that something is new or updated without showing a count, such as an “unread report”, or activity notification. It may be useful as a less prominent badge, even when the count is known.
Use badges to notify or draw attention to changed values or status.
