Black Night Drifting Bottle is a social networking app available for iPhone users. Developed by 伟强 赵, this free app falls under the category of Social & Communication.

The app allows users to send out drifting bottles, where they can write down their delicate emotions and let them float into the hands of destiny. On the other hand, users can also pick up drifting bottles and open the monologues contained within them, instantly initiating communication with the sender.

Additionally, the app features a "My Drifting Bottle" section, where users can keep a record of their conversations with each friend. There is also a personal information section, where users can design their basic information to make a good impression on new friends.
