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.
