Emotional Heatmap

Emotional Heatmap — for each day of the last 30 days, the intensity of emotion you selected is shown on a calendar heat map. Intense days in red tones, calm days in blue. Seeing emotional patterns week-by-week or month-by-month answers "why am I like this today" in a wider frame. Useful uses: noticing which week you're crashing (hormonal cycle, season, stressful work week?), which days are consistently high (Friday evenings? Monday afternoons?), tracking your responses to triggers over time. Astrological context: comparing this visual to the lunar cycle may reveal patterns like sensitivity at the full moon, reset at the new moon.
