Chick Button Baby stops crying

What is a chick button ,,,
When the baby started to cry, it was invented to express the intention of the surrounding people "It is not annoying"
It is an idea to install it in a place such as a public facility, a bus, a train.
However, considering the cost of installation, it was still far from realization to realize, and it was decided to spread it as a smartphone application.
With this application, along with the original role of the chick button, we prepared many variations of the voice so that the baby stops crying by listening to the sound.
It's okay to collect cute illustrations, loop it down and use it as a background music, and there is not always one use.
Nice to meet you.
