How closely did today match what you expected?

DayDelta helps you predict how your day might go, reflect on what actually happened, and notice small differences between expectations and reality.

No need for a long diary. Record your mood, energy, and stress levels, then discover patterns in your daily life as your entries grow.

■ Look Ahead to Your Day

How do you think today will go?
Take a moment to predict your mood, energy, and stress levels.

A small entry in the morning gives you something to look back on at the end of the day.

■ Reflect at the End of the Day

Record how your day actually went and compare it with your earlier expectations.

Notice what often goes as expected and what tends to turn out differently.

You can revisit and edit past records whenever you need to.

■ Discover Patterns Over Time

Monthly reports and personal patterns help you explore differences between expectations and reality, changes in mood, energy, and stress, and recurring themes.

Choose different time periods to see how your experiences change.

As your records grow, the rhythms of your daily life become clearer.

These reports are not scores meant to judge or diagnose you. They help you revisit your experiences and understand yourself a little better.

■ Explore Patterns in Your Notes

Analyze notes written in Korean, English, or Japanese directly on your device to find frequently used words, expressions, and recurring themes.

Notes mixing these languages can also be analyzed. Your notes are not sent to an external AI server for text analysis.

Even short notes can become meaningful personal records over time.

■ One Card a Day

Draw a card each day and explore its interpretation.

Your cards and interpretations are saved in a card gallery, so you can revisit them later.

Discover different decks and enjoy building your collection.

The daily card is optional and separate from your daily records. Card interpretations do not affect your daily records or pattern calculations.

■ Find Little Joys in the Atelier

Add a touch of fun to your daily reflections.

Complete daily, weekly, and special missions, collect rewards, and explore the Atelier.

Find stickers and card decks in the shop, discover items in the workshop, and view what you own in your collection.

Use collected items to decorate your records and screens, making DayDelta your own.

■ Record at Your Own Pace

You don't have to write every day.

Missed days are never marked as failures, and there's no pressure to fill in past entries.

Keep your diary at a pace that feels right for you.

■ Reminders When You Need Them

Turn prediction and reflection reminders on or off separately and set the times that suit your routine.

■ Your Records Stay on Your Device

Your predictions, reflections, notes, and analysis results are stored locally on your device by default.

Use backup and restore when you want to keep a copy or move your records to another device.

DayDelta doesn't tell you the right way to live your day.

Record your experiences, reflect on what was different, and discover your own patterns over time.

Small differences can lead to new ways of understanding yourself.
