ColorDiaryApp

Record one color a day, review the colors you chose in plain language, add 800-character memos, use widgets, share tiles, and keep manual backups.

Not every day needs words. A color is enough. ColorDiary is a simple mood journal where you record your day with one color.

Pick the color that matches how you feel, and save. Add an optional memo whenever you want—up to 800 characters. Over time, your calendar turns into a colorful mosaic, making patterns easy to spot at a glance.
