Why does earning time change the homework fight?
The hard part of homework is often starting, not finishing. When the reward is vague and far away, a ten-year-old has little reason to open the folder now. Earnest makes the trade concrete: finish this, earn that, and the apps you like open sooner. Because you approve the quest, you stay the judge of what counts as done, and you can keep the learning bonus modest so the habit matters more than the payout.
