Starting a conversation is the first step towards a healthier mind

Here, we listen to your story with care and are ready to walk alongside you as your supporter.

In today's society, mental health has become an increasingly important issue. Particularly, the serious situation of depression

among married women, who are often overlooked, has drawn attention. Sokdak Sokdak was created to support

women facing such difficulties. During the planning phase of our service, various research efforts were made to establish a community

that serves as a psychological support system for women beyond just a women-only community.

freely share their concerns for their well-being.

understanding of our target users' pain points and needs.

status is as high as 78%.

are satisfied with the service and hope for its official release.

About 200 beta tests were conducted, and the initial goal of achieving 100% user satisfaction was met. Through the tests, it was confirmed

that many users want to communicate in more diverse ways. Subsequently, the service usage pattern also showed that users were chatting using emojis
embedded in the operating system. Building on this, the focus shifted to enhancing communication by using emojis in chats to express various emotions.

Following this, discussions were held regarding the possibility and scalability of exchanging messages via audio, considering user needs.
