A shared diary that starts with one question a day.
우리사이 (Woori Sai) is a daily Q&A app for couples. Answer the same question each day; your partner's answer stays hidden until you both reply. Two compatibility scores grow together: how alike you answer, and how well you predict each other.
- Five questions a day across 9 categories, 340 questions
- Answers reveal in handwriting only when you both reply
- Two-axis compatibility: similarity & understanding (prediction game)
- A couple map that lights up new places as your answers stack
- Weekly discovery cards and reports
- Levels, streaks, anniversaries, and 25 badges
Invite your partner and open today's first question.
