LuviDuo / How well couples know each other
How well do couples know each other? 77,354 answers
Updated November 4, 2026
Short answer: about half the time. In the Do You Know Me? game in LuviDuo, partners guessed each other's answer correctly 51% of the time, where a random guess would be right 25% of the time. Only 5% of five-question rounds were perfect.
What we found
- Everyday tastes are easier than feelings. Questions about tastes were guessed right 57% of the time, questions about deeper things 48%.
- A perfect round is rare. 5.0% of five-question rounds had all five right, and 3.8% had none.
- More play changes little. Couples guessed 49% right in their first three answers and 52% after their first 30. We can't say this is learning: couples who keep playing may simply know each other better.

Method
- Data: answers in Do You Know Me?, 5 August to 3 November 2026.
- Each answer: one partner picks one of four options about themselves, the other guesses.
- Only couples where both partners' birth years show they are adults. Minors are excluded.
- Sample: 77,354 answers, 15,270 rounds, 2,129 couples. Questions listed here have at least 100 couples each.
- Only totals are published. Nothing here identifies a person or a couple.
Limits
- These are people who chose to install a couples app and play, not a sample of all couples.
- Four fixed options are not the same as knowing someone in real life.
- We make this app, and this is not peer reviewed research.
