How many hours on the screen, or what happened inside the hour?

What happened inside the hour, not how many hours on the screen?

The common question about screens is how many hours a child spent in front of one. The sharper question worth asking instead is what happened inside that hour. An hour in which a child makes a story with a parent is a different hour from one spent sliding from clip to clip with no aim, however equal the two hours are in minutes. The first question measures time alone; the second measures what actually changed in the child: creation, movement, dialogue, learning, or the ability to stop on their own.

This difference is not a matter of phrasing. It decides every design choice that follows. A product whose success is measured by minutes spent inside it tends, often without meaning to, toward holding attention longer by any means: autoplay for the next clip, frequent notifications, rewards that keep a child coming back. A product whose success is measured by what happened during the session tends instead toward design that encourages a child to stop once the meaning is done, not only once the available content runs out.

How do we measure what happened inside the hour?

We separate six dimensions when looking at one session of a child using a digital experience. Did the child make something they can show later? Did their body move during the session, or did they stay completely still? Did a conversation happen with someone, a parent or a friend, or was the session silent on one side? Did they learn a skill usable outside the screen? Could they stop on their own once they felt satisfied, or did they only stop when asked, or stay upset about stopping? Finally, how much of the session was passive consumption, meaning content sliding by with no real action from the child at all?

These six dimensions are the basis of the Screen Value Score, a short questionnaire answered by whoever knows the session, translated into a picture of that specific hour's value, not a verdict on the child in general. We classify this tool as an internal hypothesis we are still testing, not an established scientific standard: each dimension on its own is reasonable, but combining all six into one score is a choice we designed ourselves, and it needs continued review against real use.

The general direction behind the score, moving from counting hours to looking at their quality, agrees with what independent professional bodies already publish, even though none of them names these exact six dimensions. The American Academy of Pediatrics, through its Family Media Use Plan tool on its guidance site, recommends that families set screen-free zones and times, keep a "one screen at a time" rule, turn off autoplay and notifications, choose content that teaches and inspires creativity, and review privacy settings, without setting one numeric hour limit for every case. The World Health Organization, in its guidance for the earliest years of life, sets an upper limit on sedentary screen time for very young children, and leaves the time after that limit as a space for quality rather than counting alone. This is what raises the evidence level on the general direction to professional guidance, while the six dimensions themselves, and how they combine into one score, stay a hypothesis only Dawani is testing.

What does this mean for anyone designing a product for a child?

First, it means the question "how many minutes does a child spend inside our app" is not a success question, and can be a sign of the opposite if the answer rises because of autoplay that never gives the child a real chance to stop. Second, it means every small design choice raises or lowers one of the six dimensions, whether the designer intends it or not. A "next" button that appears automatically after a few seconds raises passive consumption and lowers autonomy, regardless of how good the content it shows actually is.

Third, it means a positive conversation with a parent, even inside a digital experience, deserves a designed space rather than being left to chance. One simple on-screen question for a parent beside their child raises the dialogue dimension more than a full hour the child plays alone in silence.

What does the difference look like between two hours equal in number?

Take an illustrative example: a girl spends a full hour in an app that asks her to design a story character and narrate its adventure in her own voice, with a parent helping choose details. The hour ends with something she can show her younger brother, she talked the whole time, and she stopped on her own once the story felt complete. This is a high-value hour on nearly every one of the six dimensions.

Take another illustrative example with the exact same number of minutes: a child opens an app showing a stream of short clips, each next one starting on its own with no button pressed, no conversation with anyone during the session, nothing made, and the time ends only because a parent closed the device while the child was upset about stopping. The two hours are exactly equal in minutes, and entirely different on every other dimension worth measuring.

How do you use the Screen Value Score on your own experience?

The Screen Value Score asks you to describe one session that actually happened: the child's age, the type of activity, the session length, who was present, whether the child made something, and how the session ended. It then shows you a score on each of the six dimensions, with specific suggestions for raising the weakest one next time. Your answers are never sent to any server; the tool runs entirely inside your browser.

Use it as a mirror on one session before judging an entire product: measure one typical hour as a real child actually lives it, then ask one question about each low dimension: which design decision could raise it in the next version?

What does this score not measure?

This score describes one session. It is not an assessment of a child's development, a judgment of their character, or a measure of health or psychological impact that would need clinical expertise to assess. A high score in one session does not guarantee the next session will be as good, and a low score on one day does not mean the whole experience is bad. Combining the six dimensions into one score is also a choice Dawani designed itself, not an agreed standard in the field, which is exactly why the evidence level here is a hypothesis we are working to improve, not a settled fact. This is also where the topic connects to the wider axes of the Dawani Child-Safe Design framework, where the ability to stop is examined as its own independent axis, not one dimension inside an experimental score.

Where should you start?

If you are designing a digital experience for a child, try describing one typical session honestly before judging it by minutes. Start with the Screen Value Score, and read also how we discuss time in app as a risky metric and how we think about designing beyond screens in early childhood. You can also tell us about your product through the Start a project form.

Quick questions

Does this mean every minute on a screen has equal value?

No, that is exactly what we are pushing back on. A minute in which a child makes something or talks with someone is entirely different from a minute passed with no action at all, and that difference is what the Screen Value Score measures instead of just counting minutes.

Does the Screen Value Score replace a doctor's or specialist's opinion?

No. It describes one usage session from a product-design angle, not a medical or developmental assessment of a specific child. Any health or developmental concern deserves a specialist, not a questionnaire result.

Who is supposed to answer the tool's questions?

Whoever actually knows the session's details, usually the parent or whoever was present, or a product team describing a representative session their design is based on. The tool describes a real session only as honestly as it is described.
