What they did

Replaced email collection with phone number sign-in, which supports a social feature where users see friends' screen time, as positive peer pressure and a support group. The feature was A/B tested.

What happened

Slight uplift; people do invite friends, but not among the top wins. Still iterating.

“But so far, it has been A/B tested. It was a slight uplift. We do get people that invite their friends, but it's not in the three most meaningful wins so far.”
