Want to know what really affects your energy? Mood Trigger Calendar helps you track the small daily moments that either boost or drain your mood to reveal hidden personal patterns. Simply log quick inputs like Sunlight, Caffeine, or Clutter, tagging each as a Boost or Drain with an intensity (1β5) and optional context (Work, Home, Outside). The app transforms your data into an actionable resource. The color-coded calendar heatmap instantly shows your daily mood balance (green for boosts, red for drains). The Insights tab ranks your top boosters and drainers by impact, analyzes patterns by time of day, and shows how different contexts affect you. Built for one-handed quick logging with a customizable trigger library, this private journal helps you optimize your routine, manage your energy, and understand yourself better.
