What do you mean there are red bubbles?

In modern social tools, red bubbles can represent unread information. This is usually the little red dot that appears in the chat list when we don't click to view or reply after receiving the message. In many social media applications, we can receive a lot of information, from chatting, notifications to activity updates. So the red bubble becomes a reminder to let people know quickly whether they have important unread information.

On some special occasions, red bubbles are also widely used. For example, when we are playing a game, when there are unfinished tasks, red bubbles will be displayed on the game icon to remind us of the tasks to be completed. In addition, in some commercial software and websites, red bubbles are also used to prompt orders, coupons, news and so on. This way of using it is like putting a small red flag of the post office on the envelope to remind people that there may be something worthy of attention in the envelope.

Red bubbles are constantly evolving and expanding. On devices such as smart phones and smart watches, red bubbles not only represent unread information, but also display other reminders and notifications, such as new emails, missed calls and health data. In addition, some applications also use red bubbles for more complex reminders, such as the discovery of high-quality content, the recommendation of personal preferences and so on. This evolution shows that the red bubble has become an important way to prompt information and plays an important role in people's daily life.
