About this app

Do you know

When you are happy?
When you feel excited?
When you are sad?
When you are angry?
When you feel anxious?

Most people don't really understand their own emotions.

Because they don't know,

They can't fully enjoy moments of happiness,
And they are deeply hurt in difficult times.

When exciting moments come to you, recognize them and fully experience them.
Such moments don't come often.

These memories enrich your life.

Increase happy events,
Decrease sad ones,

And create a happier life.

The little emotion icons are cute, but currently I can't see the names of each emotion in the app The UI and some translation still needs a bit of polishing, but overall the vibe is nice, tidy and clear And a dark mode in the future would be great, thanks for your app

Is really pretty and minimalist. I wish you could have a different view because I don't like how the images are displayed.
