Headby

Why Headby

I grew up drinking water from whatever hose was nearby. There were no phones, no infinite scroll, no likes, no influencers. You spent time with other people because you had to. There was not much else to do.

For the last 25 years we have built the engagement mechanics that keep people stuck to screens. Headby is using your screen for the opposite purpose: getting people together, so that for a little while they can put their devices down.

Why knowing people nearby matters

We are not here to say phones are poison. We are here because the research on relationships is hard to ignore.

What about screens?

The evidence here is more mixed, and we try to say so.

  • Randomised trial A four-week break from Facebook

    In a randomised trial, adults who stepped away spent more time with family and friends and reported higher wellbeing.

    Allcott et al., American Economic Review, 2020
  • Contested A small average link, still debated

    Very large studies find the average link between screen time and teenagers’ wellbeing is tiny. Researchers disagree about how much is cause and how much is coincidence.

    Orben and Przybylski, Nature Human Behaviour, 2019

So we do not claim that screens cause harm for everyone. We do believe time spent together in person is good for you, and that it needs a place to start.

Most of this research is observational. It shows links between relationships and wellbeing, not proof of cause. Figures are quoted from the sources linked above and were last checked in October 2026.
