Is this your first time using Couple Diary? Couple Diary is a diary that you share with a person you love. With the Couple Diary, you and your loving partner will get one question every day. What is love? You can answer the question, or choose not to if you'd rather not. You will get one question like this, every day. Then, one year later, you will be asked the same questions. What is love? If you were shown your answer from a year ago, and asked this question again, what would your answer be? Would it be the same as it was last year? Would it be a different answer? What is love? Couple Diary, lover Diary, QnA Diary, life questions, Question Diary with questions that help me find myself, Hand-written Couple Diary is an application that you can easily use anywhere with your lover.

Can someone love two person at the same time? Do you think I\'m happy in this relationship? Have you ever wondered how it feels like to be me? If there\'s a thing that you could steal from me, what would it be? Is there someone I remind you of? How could you be sure of me? What is your favorite thing to do? Poor but good looking, rich but ugly, which one do you prefer for your lover to be? Who is your favorite fictional character ever? What does success mean to you? Describe one thing that you and I both like! I hope that your life will become even just a little bit warmer. ** Questioner - Marissa Montes - Cindy Margareth Thank you.

Verdict

The call

The clearest difference is rating: Couple Diary at 4.3 against 투다's 3.2. Couple Diary also leads on ratings volume (53 vs 10). 투다's advantage is ads (none vs shown) and update cadence (every 2 weeks vs every 4 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Couple Diary holds the better App Store score, 4.3 against 3.2. That said, the two scores are not equally well evidenced: Couple Diary has 53 ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 64% of Couple Diary's written reviews are positive against 75% of 투다's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Couple Diary ships an update every 4 months, 투다 every 2 weeks. The most recent releases landed on October 29, 2026 and October 21, 2026 respectively.
