The research

The short version of what studies say about phones, kids and family, and how Hello Hello fits. Some of this evidence is strong, some is early, and some is hotly debated. We've labeled which is which.

Survey

Parents' phones

Finding: 68% of U.S. parents say they're at least sometimes distracted by their phone while spending time with their kids.

How we match up: Your people ring the house phone, so your phone can stay in a drawer.

Pew Research Center, 2020

Correlational

“Technoference”

Finding: In 170 families with toddlers, more phone interruptions during family time were linked with more child behavior problems. It's a correlation; the authors say the direction of cause isn't settled.

How we match up: Fewer reasons to check your phone during dinner, bath and bedtime.

McDaniel & Radesky, Child Development, 2018

Small lab study

The “still face” with a phone

Finding: When mothers turned to a phone and stopped responding, babies showed less positive and more negative emotion, echoing the classic Still Face experiment. A small lab study (50 babies).

How we match up: A home phone with no screen has nothing to get lost in.

Myruski et al., Developmental Science, 2018

Government advisory

Kids and social media

Finding: The U.S. Surgeon General's 2023 advisory says we can't conclude social media is sufficiently safe for kids, and that teens on it over 3 hours a day face double the risk of depression and anxiety symptoms.

How we match up: Kids get a phone to talk to their people, with no apps or feeds.

U.S. Surgeon General's Advisory, 2023

Debated

Phone-based childhood: the debate

Finding: Jonathan Haidt argues smartphones and social media helped cause a rise in teen anxiety and depression. Other researchers, like Candice Odgers, say the evidence mostly shows small or mixed links, not proof of cause.

How we match up: We don't need the debate settled to offer a simple choice: a way for young kids to call family without a smartphone.

Haidt, The Anxious Generation; Odgers, Nature, 2024

Parent movement

Waiting on smartphones

Finding: Wait Until 8th asks parents to pledge to hold off on a smartphone until at least the end of 8th grade, together with other families. It allows basic phones for calls and texts.

How we match up: A kids' line that rings the house fits right in with waiting.

Review

Kids' independence

Finding: A review in The Journal of Pediatrics argues that less independent play and activity is a major cause of declining kids' mental health. The authors note the evidence is largely correlational.

How we match up: Kids answer their own calls, and soon can call approved people on their own.

Gray, Lancy & Bjorklund, 2023

Correlational

Grandparents

Finding: In a study of about 1,500 English and Welsh teens, more grandparent involvement was linked with fewer emotional problems and more kindness to others. A survey, so it shows a link, not a cause.

How we match up: Grandma gets her own ring, and the kids pick up.

Attar-Schwartz et al., Journal of Family Psychology, 2009

Government advisory

Loneliness

Finding: The Surgeon General's 2023 advisory calls loneliness a public health crisis and urges simple steps, like answering a friend's call and listening without your phone.

How we match up: A phone in the kitchen makes calling family an everyday thing.

U.S. Surgeon General's Advisory, 2023

Mixed evidence

Phone-free schools

Finding: An English study of 30 secondary schools found phone bans cut phone use during school, but students at restrictive schools didn't have better mental wellbeing. The authors say school bans alone aren't enough.

How we match up: Phone habits start at home. Hello Hello is a home tool, not a school policy.

Goodyear et al., Lancet Regional Health – Europe, 2025

Industry estimate

Spam calls

Finding: Americans got about 3.8 billion robocalls in September 2026, around 11.7 per person, by YouMail's estimate.

How we match up: Callers who aren't on your list and don't have your PIN never ring the house.
