Review momentum
ⓘ How we measure thisReview momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.
About OneBook: Daily Diary & Journal
"You don't have to write every day. Only the words you write become a book."
OneBook Journal is a diary app where consistency isn't the goal.
It's okay to skip days.
But the words you do decide to write will safely remain here.
Skipping a day is never a failure.
This isn't a "record of hard work," but rather a "collection of days you wanted to write."
In a quiet place meant only for you, why not spell out fragments of your daily life?
■ The Quiet Rules of OneBook Journal
1. 30 Written Pages Make a Book
・1 entry counts as 1 page.
・Only the pages you write are accumulated. When you reach 30 pages, a book is automatically completed.
・Unwritten days do not create blank pages, so your book will only contain the words you needed.
2. Write Whenever, Whatever
・A single line or a long entry—both are perfectly fine.
・Morning, night, or even after a few days' break. Your diary exists only in the moments you feel like writing.
3. Trace Your Emotions in Color
・Record your "mood" of the day with a simple stamp.
・Your recorded moods color the calendar, allowing you to quietly reflect on your emotional waves over time.
4. Save Touching Words to "Favorites"
・Add a star to the pages you want to reread again and again.
・They gather into a "Special Book," becoming a collection of words that encourage you anytime.
5. Completed Books Go to the Library
・Finished books line up in your library, ready to be flipped through like a real book.
・Past books cannot be edited, preserving your exact feelings and words from that moment.
6. Completely Private. No Comparisons.
・No social media sharing, no "likes" or evaluations.
・A private space where you can face your own heart without worrying about anyone else's gaze.
7. Minimalist & Simple
・Just open the app and write. A modern, calming design stripped of complex settings.
■ Perfect For:
・People who have struggled to keep a diary in the past.
・Those who feel burdened by the pressure of "writing every day."
・Anyone wanting to save fleeting thoughts or emotions.
・People who feel guilty seeing blank pages in a journal.
・Lovers of the quiet atmosphere of paper notebooks.
Only the pages you write become your unique book.
