A diary app that helps you notice changes in your "good days"
Simply choose one of three options each day.
The habit of choosing today's day from "Good Day / Average / Bad Day" in just three seconds will help you notice the changing "measure of a good day" within you.
■ No need to wonder what to write. That's why it lasts.
The three-option diary is for people who have never been able to keep a diary. Because you don't have to think about what to write, even on busy days or days when you're not in the mood, recording is completed in three seconds. There's zero guilt even if you miss a day.
■ For those who:
・Start a diary but give up after three days
・Want to know more about their own feelings and values
・Feel like they're just drifting through each day
・Want to use a calm, ad-free app
■ You will change in four steps
STEP 1 | Keep recording
3 seconds, 3 choices. Its simplicity prevents frustration, making "continuing" the first step.
STEP 2 | Getting to Know Yourself
Based on psychological theories (Schwartz's Values Theory, VIA Strengths Assessment, Big Five), AI analyzes your values, strengths, and personality from your records. You'll discover aspects of yourself you weren't even aware of.
STEP 3 | Gaining Insights
Daily reflection reports gently articulate your emotions and the context of the day. In addition to weekly and monthly reports, there are also special reports. This is a diary experience that goes beyond simply "writing and forgetting."
STEP 4 | Noticing a Shift in Your Scale
As your records accumulate, you'll see how your definition of a "good day" has changed over time. You'll become aware of the gap between your assumptions and your true feelings, and learn to cherish what constitutes a "good day" for you now.

"The method I described as the 'Calendar Circle/X Method' in my book 'The Mechanism of Happiness' has evolved."
