About this app

Before you lose track of your daily mood and the good things that happened.

"Hitohi" is a gentle diary app that lets you record your mood in the morning, noon, and evening with stamps, and grow a plant by completing to-dos. It's perfect for those who want to look back on their mood changes and mental state later.

■ Easily record your mood in the morning, noon, and evening with stamps
Simply tap your mood three times a day. There's no need to write long sentences. Even on busy or tiring days, you can record yourself for the day in seconds. You can review your accumulated records anytime with the calendar view.

■ Your plant grows with each to-do you complete
Register the things you need to do that day as to-dos, and each time you add or complete something, your own plant will sprout and bloom. There are about 100 types of plants available, including cosmos, carnations, vinca, and tulips, so it's fun to see which plant grows. The daily accumulation of completing tasks is rewarded with visible growth, making it easy to continue.

■ Share "Good Things" in the Community
You can post and share the small "good things" that happened each day with other users. You can also send "likes" to other people's "good things," allowing you to continue recording not just silently by yourself, but also while loosely connecting with others.

■ Gentle Night Mode at Night
At night, the app automatically switches to a night mode that is easy on the eyes. Even when recording your mood at the end of the day, you can calmly reflect on it with a calm screen.

■ Recommended for:
・Those who want to look back on the ups and downs of their mood each day
・Those who have not been able to keep up with writing a diary (stamps are easy to use)
・Those who want to build a habit by accumulating small feelings of accomplishment
・Those looking for a recording app that can be continued at your own pace without difficulty
・Those who want to loosely connect with people who are also working hard every day

■ The Meaning Behind the Name "Hitohi"
As the word "hitohi" (one day) suggests, even ordinary days have meaning, not just special days. We aimed to create an app that allows you to quietly record each day in the form of mood stamps and the growth of plants.

Why not start recording your thoughts and feelings with "Hitohi," without overdoing it, but in a way that you can continue?
A mental journal app where you can record your mood with stamps, grow plants with to-do lists, and share the "good things" that happened.
