Kids app design shifting from limits to long-term learning

Excessive screen time among kids has been shown to have detrimental impacts. Tragically, research shows that even kids as young as nine or ten who spend more time on screens face a higher risk of developing mental health issues such as depression and anxiety.

That’s why, in an attempt to hold Big Tech accountable, bipartisan legislation has been introduced in the Federal and State governments across the United States. These bills focus on how we can make apps safer for kids by implementing limits: limits on screen time, limits on access to certain content, and limits on the terms they can search.

While this is a great first step, change will also need to happen at the developer level. Instead of asking “how can we make current apps safer?” we should be asking: “how can we put kids’ brain health at the center of the app from the start?” and “what if we focused on what app design could add to a child’s experience, rather than just what it should limit?”

The Brain’s Two Reward Systems

The brain has two distinct reward systems – one that governs immediate gratification, and another that controls delayed gratification. Understanding the distinction between the two is crucial for designing technology that supports long-term well-being.

The immediate gratification system, powered by the mesolimbic pathway in the brain, drives “short dopamine.” Also known as the “hot” or “wanting” system, the mesolimbic pathway presides over impulse, desire, novelty, unpredictability, and the anticipation of reward. Think of the rush you get when walking through a haunted house: each unexpected scare keeps you engaged and craving the next thrill.

Many of today’s apps for kids – like TikTok, Instagram Reels, YouTube Shorts, and even Character.AI – have the short dopamine loop down to a science (literally). These attention-based platforms benefit financially when users stay engaged, so they are designed to keep kids wanting more. Similar to using a drug or playing the lottery, kids’ brains can get hooked on these “digital narcotics.” Features of short-dopamine apps include…

Infinite scroll: 

Users can scroll on Instagram or TikTok for hours because their feed has no end. That makes scrolling difficult to stop for the same reason that slot machines are difficult to stop: you never know when the next post will deliver a big hit of entertainment, validation, or surprise, so your brain keeps chasing the “next win.”

Push Notifications:

Push notifications are a strategic way to keep users coming back. They’re constant reminders for the brain: “You’re missing out on something great.”

Variable rewards:

Many kids’ games feature “unpredictable wins,” like loot boxes. This produces short dopamine by introducing novelty – it feels like your next “reward” could always be right around the corner.

Autoplay:

Many video-based apps, such as YouTube and Netflix, use autoplay, eliminating natural stopping points that would otherwise give users a chance to pause or take a break.

Introducing Healthier Design

A “long dopamine” system is one that’s designed to support delayed, meaningful rewards through sustained effort and patience. Consider the feeling you have after cooking a meal: while the process of chopping, sauteing, or waiting for an oven to preheat may feel mundane – even boring – in the moment, the sense of accomplishment and pride you receive when it’s done is deeply rewarding.

Apps designed with long dopamine in mind work the same way. They foster motivation, build focus, and strengthen resilience and goal-setting skills. Here are some key ways developers can integrate long dopamine design into the apps they create:

Finite design: 

Instead of endless scrolling, apps built with long dopamine in mind have a natural stopping point that respects kids’ time. Interestingly enough, early versions of Instagram had this feature. Users would receive a pop-up message that said “you’re all caught up!” after they had finished scrolling through every post from the past 48 hours.

Goal Orientation: 

Breaking tasks into manageable, motivating steps helps kids stay focused without feeling overwhelmed. For example, a learning app might break up a 30-minute lesson into three 10-minute challenges, each with its own small reward.

Meaningful Progress: 

Apps can feature visual tools, like daily streaks and progress bars, to show how effort adds up over time. Forest is one example – it's a productivity app that grows a virtual tree when the user focuses on a task for an extended period.

Intentional Friction: 

Contrary to YouTube Kids’ autoplay features, platforms can build in intentional pauses that interrupt short-dopamine loops and promote conscious choices. Apps like Elqi layer this friction in – when a user tries to open a distracting app, Elqi intervenes with a mindfulness exercise, encouraging a conscious choice and breaking impulsive habits. 

What’s Next for Kids app design?

The science is clear: when it comes to protecting kids’ mental health, content blockers and screen time limits won’t be enough. Developers need to rethink the very architecture of the apps they design for kids, and how those apps will be monetized. 

While change won’t happen overnight, the app developer community is now presented with an opportunity to help the next generation build skills they will need for the rest of their lives, like patience, critical thinking, motivation, and attention — if that design is prioritized like it should be.
