What is Daylio?
Daylio is a digital journaling and mood tracking application designed to help users monitor emotional states, daily activities, and personal progress over time. Its primary purpose is to provide an intuitive way to log moods using a simple scale, record activities, and analyze patterns through visual data representations. The tool caters to individuals seeking to improve mental health awareness, enhance productivity, or maintain a structured daily routine. By combining mood tracking with activity logging, Daylio addresses the need for personalized self-reflection and behavioral insight, particularly for those managing stress, depression, or goal-oriented lifestyles. The platform emphasizes privacy and ease of use, making it accessible for users of varying technical skill levels.
How it works
Daylio functions as a mood and activity tracker that allows users to log their emotional state and daily activities in real-time. Its core purpose is to enable self-awareness by correlating mood fluctuations with specific events or habits, helping users identify triggers and trends. The tool is particularly useful for individuals exploring mental health management, habit formation, or personal development. By offering a visual summary of daily entries, Daylio transforms abstract emotional experiences into actionable insights. Users can select from a predefined mood scale or customize emojis to represent their emotional state. Activities are logged with tags, and optional notes, photos, or voice memos add depth to entries. Data is visualized through charts, correlation stats, and a 'Year in Pixels' timeline, enabling users to track progress over time.
How to use it
- 1Open the app and select a mood from the scale or add a custom emoji. 2. Log activities by tapping pre-defined tags or adding custom ones. 3. Add notes, attach media, or record voice memos to contextualize entries. 4. Review data in list, calendar, or chart views to identify patterns. Practical tips include using writing templates for consistency, leveraging the 'Year in Pixels' feature for annual retrospectives, and setting reminders to maintain daily tracking habits.

Frequently asked
How does Daylio handle data privacy and security?
Daylio stores user data on its servers with encryption measures to protect sensitive information. While the app offers PIN locks and biometric authentication for local data access, all entries are stored in the cloud. Users should assume data is accessible via the app's infrastructure, though the platform claims to prioritize privacy through anonymized analytics and optional export features.
How does Daylio's correlation analysis work?
The app uses statistical algorithms to identify patterns between logged moods and activities. For example, it might show a trend of lower mood scores coinciding with specific tasks or times of day. These correlations are visualized in charts and stats but do not imply causation, as they rely on self-reported data rather than scientific measurements.
How do I export my mood data as a visual summary?
Navigate to the 'Year in Pixels' feature, which generates a single-image timeline of daily entries. Tap the export option to save the visualization as a downloadable image. This allows users to share summaries with others or use as a reference for self-assessment.
How does Daylio compare to alternatives like Moodpath or Day One?
Daylio focuses on simplicity and mood-activity correlations, while Moodpath emphasizes mental health tracking with professional tools. Day One prioritizes journaling with minimal structure. Daylio's strength lies in its visual analytics and ease of use, whereas alternatives may offer more advanced features like therapist integration or detailed journaling templates.
What should I do if I can't log into my Daylio account?
First, verify your email and password for typos. If issues persist, check the app's support documentation for account recovery steps. If problems continue, contact Daylio's customer support team via their official channels, providing details about the error message or login failure.
