In plenty of houses, screen time is the only currency that still clears. Pocket money is abstract, stickers are for babies, and the tablet is right there on the sofa. So should kids earn screen time with chores, and how do you stop it turning into a trade negotiation every evening?
This is one of our guides to rewards, charts and what the research says about them. The short answer is yes, with a ceiling.
Does earning screen time work?
For getting jobs done, often. Children want it, and wanting is the whole engine of a reward. A meta-analysis of 183 studies and more than 212,000 people, across school, work and sport, found incentives were the better predictor of how much people did. Their own motivation better predicted how well. Every study we cite is listed on the home page, with its limits.
The cost turns up elsewhere. A meta-analysis of 128 experiments found that rewards people expected, for doing or finishing a task, reduced how much they chose to do it afterwards, and tangible rewards tended to be more detrimental for children than for university students. Positive feedback increased interest. We know of no reason screen time would be the exception.
Two details from the full paper soften that. The undermining showed up with tasks people already enjoyed, not boring ones, and hoovering the stairs is rarely anybody's passion. And rewards given as a surprise, after the job, made no measurable difference.
The risk: screens get even more valuable
A Canadian study of 62 children aged 18 months to five years asked parents whether they offered screen time as a reward for good behaviour, or took it away as a punishment. Where mothers did more of this, children had more screen time on weekdays. Where either parent did, they had more at weekends.
It is small, it is a snapshot rather than a trial, and the children were very young. The authors point out it may run the other way: parents may pick screens as the reward because their child already loves them. Treat it as a warning sign, not a finding about your eight year old.
The worry holds up without a study. Make one thing the prize for everything and you have told your child it is the most valuable thing in the house.
What the evidence says about screen time itself
A 2019 systematic review in BMJ Open pulled together 13 earlier reviews. It found moderately strong evidence linking more screen time with obesity and more depressive symptoms, and moderate evidence linking it with a less healthy diet and poorer quality of life. Evidence for most other outcomes, sleep included, was weak or missing. It also found weak evidence that small amounts of daily use are not harmful and may have some benefits.
These are associations. They cannot tell you whether screens cause the harm or whether children who are already struggling use more screens. The same review found the evidence for any safe threshold weak. A separate analysis of three large datasets, covering 355,358 teenagers, found the link between digital technology use and well-being was negative but small, explaining at most 0.4% of the variation.
So there is no evidence-based number of minutes to aim for. Set your ceiling on your own terms first. Then decide how much of it chores can earn.
How to set it up without a nightly negotiation
- Set the ceiling first. The most screen time you are happy with on a school day, decided before chores come into it. Chores earn time inside that, never past it.
- Keep a base allowance. If every minute has to be earned, screens become the whole economy and one bad day means none at all.
- Fix the exchange rate and write it down. Ten minutes of screen for a ten minute job, timed on a timer you can both see, is easy to remember. A rate agreed on Sunday is not up for debate on Wednesday.
- Keep the basics out of it. Clearing their own plate earns nothing. Otherwise you will be negotiating over teeth by Thursday.
- Set cash-in times. After tea is fine. Bedtime is a bad moment to be settling accounts.
- Do not take earned time away for something else. Once a reward can vanish, the deal stops being a deal.
- Praise the job, not just the minutes. Feedback was the clearest effect in that research pointing the right way.
That rate card is your screen time reward chart: jobs, minutes, daily maximum, cash-in times. Nothing else needs to be on it, and the less it asks of you each evening, the longer it lasts. Reward charts that need an adult every night tend to fade.
When screen time becomes the only currency
Watch for the signs. Every request answered with “how many minutes?”. Jobs done only when the battery is low. Screen time the only thing you ever give and the only thing you ever take away. At that point the system is running you.
- Rotate the rewards. Pocket money, choosing tea, a trip to the park, ten minutes later to bed. Paying pocket money for chores has its own rules.
- Keep some jobs unpaid in every currency. Family basics are not for sale.
- Never make it unlimited. If enough chores can buy a whole Saturday on the console, someone will find the cheapest chore and do it forty times.
Where Boomph fits
Boomph is the app we make, so weigh this accordingly. You photograph the mess and it comes back as one small mission at a time, with a timer your child can see and instant boosts during the job. The reward is whatever you type in, such as 30 minutes of a game, and you mark it handed over once they have had it. Boomph does not control screens and does not hold or move money. Boomph itself has not been trialled, and a kitchen timer and a written rate card will do most of what is above.
