> Study, record, and show off.

> An offline self-check study app for middle and high school students.

■ A Study Diary Where Scores Accumulate

"Did / Didn't" is too rough. Self-Check Study calculates session scores based on the weighted average of the reach rate relative to target time (70%) and satisfaction emoticons (30%). Even the same "Completed" is recorded differently.

■ A Month in a Single Landscape

A monthly calendar featuring 7 rainbow colors by day of the week × 5-level opacity score scales. Months with few empty cells and weeks with many dark cells are visible at a glance.

■ Real Rewards on KakaoTalk

A single word from parents, grandparents, or friends is more powerful than the scores within the app. Share your results on KakaoTalk using the system sharing sheet. ✅ Math (Online Lecture 1) Completed / 😄 92% — A one-line show-off card.
