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.

Popular uses

  • ✦ Therapy preparation—log daily mood to discuss patterns and triggers with your therapist
  • ✦ Mental health monitoring—spot how medication changes, sleep, or exercise affect your mood over weeks
  • ✦ Seasonal awareness—identify if mood shifts consistently with seasons or life transitions
  • ✦ Mindfulness building—practice daily emotional check-ins and build awareness of your inner state
  • ✦ Habit tracking—connect mood to specific habits (exercise, sleep, social time) by reviewing your calendar

Frequently asked questions

Is my mood data private?
Yes. This mood tracker runs completely in your browser and never sends data anywhere. Your mood calendar exists only on your device, with no accounts, logins, or cloud storage involved.
Do I need to sign up?
No signup required. Start logging your mood immediately when you open the tool. There are no accounts, subscriptions, or email confirmations—just you and your mood heatmap.
Can I add past moods?
Yes, you can log moods for previous dates. This is useful when you want to backfill your mood calendar with recent history or add data you forgot to log earlier.
Why use a mood tracker instead of a journal?
A mood calendar shows patterns and trends at a glance that text journaling can hide. Seeing your year-in-pixels visualization makes seasonal shifts, triggers, and emotional cycles obvious—ideal for therapy, mental health awareness, or spotting what affects your wellbeing.
Is Mood Heatmap free to use?
Mood Heatmap is 100% free — no signup, no watermarks and no usage limits. It’s one of 200+ free tools we build and give away.
Will it remember my progress?
Yes — your streaks, notes and history are saved in your browser, so everything is right where you left it.
