Mood Diary

📖 Tool Introduction

Mood Diary is a lightweight tool that helps you notice and write down how you feel each day. Psychology research shows that keeping an emotional journal improves emotional granularity, helps you spot what triggers your ups and downs, and ultimately gives you more control over your mood. This tool distils complex mood scales down to just five faces: great, good, okay, bad and terrible. Every day you spend three seconds picking the face that matches how you feel, add a few words about what happened, and that is your emotional check-in done. Below the picker, a monthly calendar colours each day according to the mood you recorded, so one glance across the grid reveals the shape of your month: which stretches were consistently good, and which days dipped low, become immediately obvious. Left and right arrows let you flip through previous months and watch your emotional trend over weeks. Days that include a note get a tiny marker in the corner, and hovering shows you exactly what you wrote. Every entry lives in your browser's localStorage, so there is no account to create, no data uploaded, and your diary stays completely private. The interface is warm and uncluttered, speaks three languages, and keeps the colour blocks soft on the eyes in dark mode. It is ideal for anyone who feels anxious, has volatile emotions, or simply wants to build self-awareness, and it is the kind of simple homework many therapists recommend to their clients. The whole point is to lower the barrier: if tracking your mood takes more than a few seconds, you will not keep it up for long, and consistency is the one thing that actually helps you notice patterns.

⚠️ Notes

• Local storage: entries live in the current browser; clearing cache erases them, so treat your diary as precious
• One entry per day: each date holds a single mood; saving again overwrites the old record for that day
• Note length: notes accept up to 300 characters, so keep them to a few sentences rather than essays
• Not medical advice: this tool is for self-awareness only and cannot replace professional therapy
• Privacy first: it runs fully offline and collects no personal data, so your mood history stays private
