This is a new music application support you play music for relaxing with the new theme.
However, the important function of this application is let you know what people talk about you when you leave. Using this function is simple. You go to the record page and click to record all the chat of people and you can go home, listen to what they talk. You cannot do this with the default record application in Iphone because they will know this and you never hear what you want.
People dont care about an iphone on the table and they still talk natural. This is what you can use.
