What the research says
Zonee is built on other people’s studies, not on its own data yet. These are the ones it leans on, what they found, and where they stop.
Putting the phone away before bed helped people sleep.
Students with poor sleep who stopped using their phone 30 minutes before bed fell asleep about 12 minutes faster and slept about 18 minutes longer after four weeks than a group that changed nothing.
Phone use in bed goes with worse sleep.
Among 844 adults, texting and calling after lights out went with worse sleep quality, more insomnia and more fatigue. A survey like this shows that the two go together, not that one causes the other.
Exelmans and Van den Bulck 2016, Social Science & Medicine. 844 adults, self-reported.
Most of the time, we pick the phone up ourselves.
Cameras worn by 37 people recorded 1,130 phone interactions. 89% were started by the person and 11% by a notification. Turning notifications off leaves most of the habit in place.
Heitmayer and Lahlou 2021, Computers in Human Behavior. 37 people.
People use limits they set for themselves.
In a trial with 1,933 adults in the US, 89% of those offered a tool to limit their own app time set limits, and their use fell and stayed down.
Allcott, Gentzkow and Song 2022, American Economic Review. 1,933 adults.
A daily cap helped within three weeks.
Students who averaged about 4.6 hours a day on their phone kept it under 2 hours for three weeks. Compared with a control group, they reported less stress and fewer depressive symptoms, better sleep quality and better wellbeing. The effects were small to medium.
Where the evidence stops
Every result here is an average over a group. For one person the effect can be larger, smaller or nothing at all.
Most of these studies are small, short, and done with students.
Nobody has tested what Zonee does: closing apps in one place, like the bed. The Zonee beta is the first test of it.
None of this says Zonee will give you more sleep. It is why Zonee starts with the bed.
About Zonee
Zonee is small and independent. The app comes first, on Android, and the first Zonee Ones are being made by hand.
