-Downloads from 236 countries
– Particularly loved in the United States and Japan

Bluesignum (CEO Junghyun Yoon), a developer of global mental wellness services, announced that its representative emotional recording service 'Harukong' has surpassed 10 million cumulative downloads worldwide. Harukong is loved by users both domestically and internationally for its easy usability and intuitive UI, and is currently actively used in 236 countries.
Harukong allows users to simply record their daily moods and activities with bean-shaped emoticons, and visualize them on a monthly calendar to help them understand the flow of emotions at a glance. The cute design and intuitive interface are popular among the global Generation Z, and its performance is particularly notable in the US market. Currently, overseas users account for more than 80% of the total, and among them, the number of users in the US accounts for the highest proportion.
Since its launch, Harukong has been selected for the Google Startup Program and has grown rapidly, attracting a total of 2.1 billion won in investments. In 2024 alone, the total number of records exceeded 29.6 million, proving high user satisfaction and participation. Recently, it signed a collaboration contract with Walt Disney Korea, a large global IP company.
The secret to Harukong's popularity lies in its simple records and rich insights. Recording a day is simple enough to be completed in a few seconds, but as records accumulate, you can check the relationship between major activities, sleeping hours, exercise hours, menstruation, etc. and emotions, allowing you to understand your emotions more deeply.
Bluesignum CEO Jeong-Hyeon Yoon said, “10 million downloads means that Harukong has naturally permeated users’ daily lives,” and added, “We will continue to work to provide an environment where users can easily record and look back on their emotions.”
