A new research poster from the School of Continuous Improvement interviews 34 households about what they do once a screen-time app's earned-minutes balance runs out, and finds its own sanctioned borrowing feature goes almost entirely unused.
Interviews with 34 households find next-day borrowing overtakes sibling swaps by the second week of the holidays, almost never through the app's own sanctioned route
The earned-minutes balance on a household screen-time app is meant to work like any ledger: spend what’s credited, and stop when it reads zero. A new research poster from the School of Continuous Improvement finds most families don’t stop — they just stop asking the app.
A ledger only holds if everyone agrees to read it the same way. By the second week, nobody in these households was reading it the same way twice.

Dr Mirela Hanke and Associate Professor Casimir Beng interviewed 58 parents and teenagers across 34 households over the two-week school holidays, coding each negotiation over spent screen time into one of four categories. Two coders worked independently and checked their categories against each other before either result counted.
Sibling swaps and chore-for-minutes trades made up most negotiated episodes in the first week. By the second, next-day borrowing — a household spending tomorrow’s balance today — accounted for 61 percent of the 212 episodes logged, up from 24 percent at the fortnight’s start. The app’s own borrow-ahead feature, the one sanctioned way to do exactly that, turned up in under 4 percent of trades in either week.
The finding lands squarely inside the School’s evaluation-ecosystem agenda, which has spent the year cataloguing what an instrument’s users do once its terms stop suiting them.
“The app was built to be the only ledger in the house,” said Associate Professor Beng. “It still is, technically. Everyone’s just started keeping a second one it can’t see.”
