OnePlusOne creates relationship tools that are evidence-based and easy to use. We combine research evidence, user experience, and ongoing evaluation to help people learn skills that will serve them in every relationship – from dating and intimacy, to parenting and co-parenting.


We use the latest relationship research to guide the way we develop our tools and deliver our support.

We explore and design with the people who will use our resources – parents, professionals, and local communities.

Our resources are evaluated and adapted to ensure they are meeting the needs of the people who use them.


Relational health is just as vital as physical or mental health. We’re creating tools that help people protect it.
