Screen Time Research Library: Explore 44 Scientific and Institutional Sources

Explore the Research Behind Screen Time Claims

Open any app in this category and you will meet a statistic. Screens do this to your sleep. Social media does that to your attention. The number is confident, the source is absent, and you are expected to take it on faith from a company that wants your subscription.

Upchin ships the sources instead. Forty-four of them, each with its reference, its year and a link to the original — so the sentence on the marketing page and the paper behind it are one tap apart.

Explore 44 Research Sources Across Eight Topics

The library is browsable by topic rather than searchable, because forty-four items across eight topics do not need a search engine. The topics are the ones the research actually clusters around: the brain and attention, social relationships, road safety, digestion, work, eyesight, posture, and doomscrolling itself.

Each source is a card, and the card is structured rather than summarised. It tells you the type of source, the year, the population or data it looked at, the exposure it studied, and the finding as reported. Then the full reference, and a link out.

You are meant to be able to disagree with it.

Understand Key Screen Time Research Terms

Twelve concepts explained without jargon — the terms that get thrown around in this field and rarely defined.

⚠️ These definitions are written for the app. They are not quotations from the literature, and they do not pretend to be: they are our plain-language explanation of a term, which is a different kind of thing from a cited finding.

What the Evidence Cannot Say

This is the part a marketing page would leave out. It is in the app, on the library's own screen:

This library presents scientific and institutional research for information only. The studies cover different populations, contexts and methods. An observed association does not mean a cause-and-effect link has been demonstrated.

And:

This information is not medical advice.

We think this makes the library more useful rather than less. Research on screens is genuinely mixed, the methods vary enormously, and a lot of what circulates online is a confident claim built on a correlation. An app that handed you forty-four papers and implied they all prove the same thing would be doing exactly what it criticises.

What the Science Library Is Not

It is not a recommendation engine. The library has no connection to your blocks, your rules or your figures. It does not know what you use and it does not adapt to you.

It is not behind the subscription. It is available whether or not you pay.

It is not online. The whole corpus ships inside the app, in all twenty-one languages. Nothing is fetched, nothing is logged, and no account is involved — reading a paper about sleep does not tell anyone that you were reading about sleep.

It is not exhaustive. Forty-four sources are a starting point for your own reading, not a review of the field.
