How it works

We compare your answers
Sincera looks at where you both feel strong, where you differ, and which patterns the research says matter most, weighing things like repair and respect, the strongest predictors of a relationship that lasts.

You both receive the same private report: your relationship health score, the strengths to celebrate, and small, proven moves for the areas that need care, each one drawn from the research, emailed to you both.
