Mood Note

A privacy-first, minimal mood tracker to log emotions and energy on a 2-axis scale, operating fully within your browser.

Lately, we’ve seen a rise in "mood trackers" and "emotion log" apps to record daily mental waves. However, have you ever felt any of the following frustrations when actually using them?

  • Too many features and items, making daily input a hassle.

  • The design is too flashy, or it’s a foreign app with unnatural translations that don't feel calming.

  • Anxiety that your delicate emotional data, which you don’t want anyone to see, is being sent to some server.

While trying out various tools myself, I felt that I wanted a place where I could use it more casually and with peace of mind.

Therefore, I created a mood tracker (Web app) that requires no installation, pursuing the concepts of being "simple, private, and smooth."


🌟 What You Can Do

This app is a self-care tool to record daily "mood (emotion)" and "energy (vitality)" along with "activities (tags)" at that time to visualize your own mental balance.

  • Intuitive 2-Axis Logging: You can intuitively record your "mood" and "energy" with just a few taps.

  • Easy Factor Analysis: You can easily analyze what you were doing (such as "Work," "Exercise," "Sleep") when your energy goes up or down.

  • PWA Support: No need to go through app stores. Just open it in your browser and add it to your smartphone's home screen to run smoothly in full screen like a real app.


🔒 Commitment to Trust and Privacy

The record of your mind and emotions is the ultimate personal information for anyone. That's why we designed this app with "data safety" as the top priority.

【Complete Data Protection】 All recorded data is saved only inside your smartphone (browser). It is never sent to an external server. Since no account registration is required, the risk of personal information leakage is zero.

Your data belongs to you. With that peace of mind, you can relax and keep your daily logs.


👥 Who is this for?

I especially want people with the following challenges or needs to use this app:

  • Those who want to know the pattern of their "good mood"

    • Perfect for those who want to visually understand their unconscious biorhythm, such as "For some reason, I don't feel motivated today" or "I'm always tired on this day of the week."

  • Those who couldn't keep up with existing apps

    • You don't need to write long texts like a diary. It takes just a few taps with icons and sliders, so even busy people or those who tend to give up easily can continue.

  • Those who prefer a clean, calm design

    • We adopted a clean and minimal design inspired by current wellness philosophies. We aimed to create a space where just opening the app makes you feel a little calmer.


Conclusion

"Looking at your condition objectively" becomes a powerful self-care skill to survive in today's stressful society.

Why not start with a "1 tap a day" when you feel like it?
