About Mood Heatmap
Mood Heatmap is a free mood tracker that visualizes your emotional patterns as a year-in-pixels calendar. Log how you're feeling in one tap each day and watch your mood calendar fill in like GitHub contributions. It's the simplest way to track mood over time without complexity or account creation.
Your daily mood logs form a visual heatmap across 12 months, making it easy to spot patterns, recognize triggers, and see how your emotional landscape shifts with seasons, life events, and habits. Each day is one color representing your mood—no lengthy check-ins required, just honest one-tap logging that takes seconds.
This mood calendar runs entirely in your browser with no data collection or cloud uploads—your mood tracker stays on your device. Perfect for journaling, therapy preparation, spotting seasonal changes, or simply building awareness of your emotional patterns throughout the year.
