About this app

For everyone's peaceful days, ‘EgoBook,’ an emotion recording service with your own personal turtle.

Do you need time to care for your heart amidst your busy and exhausting daily life?

EgoBook is a healing emotional diary app that helps you grow emotionally by recording your feelings and exchanging warm comfort with your own companion turtle, ‘Gobugi.’

Tell EgoBook how you felt today and what worries you have. Gobugi will always be by your side to listen to your story so that your heart can find peace!

[An Emotional Diary to Look Inside Your Heart]

• Freely record your emotions, which change several times a day, using 5-level emoticons and text.

• Go beyond a simple diary; you can cultivate a positive mindset by writing entries categorized into ‘Worries,’ ‘Praise,’ and ‘Gratitude.’

• Use the calendar to get a quick overview of how you felt throughout the month, and export your precious records as PDF or text to cherish forever.

[Warm Comfort and Support: Ego Room and AI Compliment Letters]

• Based on the diary entries you have carefully written, AI sends you a personalized 'Daily Compliment Letter' just for you every midnight.

• Boost your self-esteem by reading messages of comfort and encouragement for yourself.

• You can also analyze the flow of your emotions more objectively and deeply through weekly AI counseling reports and emotional statistics graphs.

[A Safe and Friendly Communication Space: Ego Plaza]

• If you have worries you cannot share with anyone, send an anonymous letter across the ocean. You can find great comfort by exchanging replies filled with warm empathy with unfamiliar turtles.

• With a 'Bad Language AI Filtering' feature that filters out hate speech and profanity, anyone can communicate safely without worrying about getting hurt.

• Write down answers to the 'Question of the Day' provided daily, and share your thoughts by comparing your turtle with your friends'!

[Decorate Your Own Turtle That Grows the More You Record]

• Every time you engage in positive activities, such as writing a diary or sending letters, your five mental stats—Empathy, Self-Esteem, Emotional Regulation, Positive Thinking, and Diligence—grow rapidly!

• Decorate your own turtle by purchasing shells, skins, and cute decorations from the shop using "Ink" collected by completing in-app activities and attendance missions.

• Don't miss out on the delightful fun of collecting "Psychological Knowledge" notes found inside glass bottles that wash ashore every day.

Spend just 5 minutes a day with EgoBook to build a warm habit of caring for your mind.

The EgoBook team wishes you peace and well-being every day.
