About Daylio

Daylio is a mood tracking app designed for people who don't like writing. Instead of journaling, you select a mood icon and tap which activities you did that day. Over time, Daylio shows you patterns: which activities correlate with better moods, how your mood changes over weeks and months, and what your baseline mood looks like. It's fast (under 30 seconds per entry) and gamified with streaks and achievements.
