For grown-ups
DuskTales is bedtime math. You read a short story aloud (or tap to hear it), then your child picks one of three doors — Wee for ages 3 to 5, Little for 6 to 7, Big for 8 to 9 — and you ask the one question behind it. Your line is printed under the door, so you never have to invent the math.
Any night you like; in the study, families who used it on more nights saw more gain. The story ends with the lantern going out, and there is no next story button. A wrong answer opens the door anyway, and the story shows the counting together. This design follows the published Bedtime Math study, a randomised trial with 587 first-graders (Berkowitz and colleagues, Science, 2015), which found the biggest gains for children of math-anxious parents; we describe the design, we do not claim the same results.
What it never does
- No accounts, no ads, no tracking — anything kept stays on this device.
- No streaks, timers to beat, points to chase or leaderboards.
- No chat, and nothing anyone types is sent anywhere.
