Pixel Diary: Mood & Pixel Art

Log your mood. Unlock a pixel art puzzle. Watch a picture come alive — one piece per day. Pixel Diary turns your daily mood check-in into a month-long pixel art reveal. Tap your mood, add a quick note, and one puzzle piece unlocks. Do it every day and a hand-crafted retro illustration — tanabata stars, summer fireworks, autumn leaves, Christmas lights — completes itself by the last day of the month. No account. No cloud. Your data never leaves your device. HOW IT WORKS 1. Once a day, rate your mood on a 5-level scale. 2. Add an optional note (just a few words is plenty). 3. One puzzle piece unlocks immediately — you can see it fill in on the canvas. 4. Come back tomorrow and the picture grows. 5. On the last day of the month, your illustration is complete and ready to share. The artwork stays hidden until the pieces are revealed, so every log feels like scratching a lottery ticket — except the prize is a piece of art you built yourself. 24 SEASONAL ARTWORKS — 2 FULL YEARS Each month has its own unique 8-bit illustration themed around seasonal events: Year 1: Tanabata, Summer Fireworks, Harvest Moon, Halloween, Autumn Foliage, Christmas Town, New Year's Sunrise, Setsubun, Hinamatsuri, Cherry Blossoms, Koinobori, Hydrangea Year 2: Beach Opening, Summer Festival, Cosmos Field, Maple Valley, Bonfire Night, Cozy Christmas, Snowy Shrine Visit, Snow Festival, Canola Field, Night Sakura, Wisteria, Fireflies FEATURES - 5-level mood log with an optional text note - One puzzle piece unlocks per log — see it appear in real time - Streak counter keeps your run visible at a glance - Gallery of all completed artworks — yours to revisit anytime - Share completed art to Instagram, X (Twitter), LINE, or copy to clipboard - 8-bit sound effects and subtle animations (retro game feel) - Face ID / Touch ID lock for privacy - Daily reminder notification — set your own time - Dark and light mode - Available in English, Japanese, Korean, and Hindi PRIVACY & PRICING All data is stored on-device.
