ColorDiaryApp

Record one color a day with quick, simple Basic 24 or more nuanced Expanded 55. Learn how colors work, review your choices, add memos, and back up.

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.
