마음정원 is a free iPhone app developed by Haii in the Lifestyle category, specifically under Health & Fitness. The app offers a digital therapeutic service where users can spend time in their own "mind garden" to reflect on themselves and their emotions.

마음정원 provides content based on the user's chosen emotions, allowing them to read and revisit the content at any time. The app incorporates cognitive behavioral therapy techniques such as acceptance and commitment therapy and self-affirmation to comfort the mind and provide a new perspective on worries and concerns.

The app features two types of self-talk: reading the content aloud to oneself and speaking to oneself. Users can engage in these processes while immersing themselves in calming music, engaging in breathing exercises to nurture the mind and body, and keeping a record of their emotional weather.

마음정원 offers daily changing content, personalized to suit the user's emotions. With the ability to record and bookmark content, users can access their desired content at any time.

Please note that 마음정원 requires access to the microphone for the read-aloud and speaking features, as well as access to notifications for push notifications.
