What Is a Mood Tracker?
A mood tracker is a simple tool for logging how you feel each day. By recording your emotional state consistently, you build a personal dataset that reveals patterns — which days tend to be harder, what activities improve your mood, and how your well-being changes over time.
Research shows that the act of identifying and labeling emotions (called “affect labeling”) can itself reduce the intensity of negative feelings. Combining mood tracking with brief journal notes creates a powerful daily reflection habit used by therapists and mental health professionals worldwide.

2. Add an optional journal note about your day or what's on your mind.
3. Save your entry — it's stored locally in your browser.

Frequently Asked Questions
Is this mood tracker free and private?
Yes — 100% free with no signup required. All your mood data is stored locally in your browser's storage. Nothing is ever sent to a server, so your emotional health data stays completely private.
How do I use a mood tracker effectively?
Log your mood at the same time each day for consistency — many people prefer morning or evening. Add a brief note about what influenced your mood. Over weeks, patterns emerge that help you understand what triggers good and bad days.
Can I see mood trends over time?
Yes. The tool visualizes your mood history so you can spot trends, identify recurring patterns, and see how your emotional well-being changes across days and weeks.
Will my mood data be saved if I close the browser?
Your data persists in your browser's local storage, so it will be there when you return — as long as you use the same browser and don't clear your browsing data. For long-term backup, you can export your entries.
Can I add journal notes along with my mood?
Absolutely. Each mood entry includes space for free-form journal notes where you can write about what happened, what you're grateful for, or anything else on your mind. Combining mood tracking with journaling is a powerful self-reflection habit.
