The science

Built on 40 years of relationship research

Dr. John Gottman spent four decades inside his "Love Lab," studying over 3,000 couples. His framework predicts divorce with greater than 90% accuracy — and pinpoints exactly what makes relationships last.

He identified the Four Horsemen — criticism, contempt, defensiveness, and stonewalling — that quietly erode connection. Contempt is the #1 predictor of breakup.

Stable couples maintain a 5:1 ratio of positive to negative interactions. nuttr turns this science into a number you can actually track.
