About Daylio

Daylio is a popular mood tracking app designed for people who don't like writing. Instead of journaling, you select mood levels and activities using icons. The app shows patterns over time—which activities correlate with better moods, how you feel on different days, and long-term trends. Daily reminders help build tracking habits. Data can be exported and shared with therapists. The free version provides core tracking; premium ($2.99/mo) adds advanced statistics and unlimited entries. Daylio has been downloaded millions of times and is particularly popular with people who find traditional journaling burdensome.
