In the modern fast-paced life, there is a certain amount of pressure at any age, such as learning pressure, work pressure, psychological pressure and so on. Even many young people lose their lives because of depression and stress. When there is a certain pressure, how to release the pressure and vent the pressure, therefore, we designed a decompression APP, making APP a vent channel...... This APP for any age group, users vent through the APP, listen to the music created after the vent, harvest plant planting to relax, anonymous spit unhappy, comfort others or get comfort, etc.... Let the user relax in the process of use. After investigation, it is found that most people's pressure comes from life pressure, academic pressure and interpersonal pressure. When talking, many people choose to talk in private space or publish in places with only strangers. In the expected APP function, it is hoped that things will be destroyed, things will create music, and people will talk about their unhappiness. Therefore, in the APP function setting, it is committed to venting, creating things and talking about these three functions.
