For ages 3 to 6. Your child plays with sounds and pictures. Nothing to read.
No account, no ads, nothing to buy, no links out. Nothing your child does leaves this device. It works offline once it has opened. To leave, hold the corner button for 2 seconds.
I.What it teaches, and why
Letters through their sounds. Each letter says its sound and shows a picture that starts with it. Phonics taught early helps reading: d = 0.41, strong evidence. Ehri and others 2001 (National Reading Panel), doi 10.3102/00346543071003393
Counting and shapes through guided play. Your child plays and a light hint steers. Guided play beat direct teaching on early math (g = 0.24) and shapes (g = 0.63), moderate evidence. Skene and others 2022, doi 10.1111/cdev.13730
No stars, coins or streaks. It says what they did ("you found 3"). Rewards cut later free choice to play (d = −0.28 to −0.40); honest feedback helped (d = +0.33), moderate to strong evidence. Deci, Koestner and Ryan 1999, doi 10.1037/0033-2909.125.6.627
Your child picks what to play. Choices go with motivation, moderate evidence, mostly from studies that watch rather than test. Vasquez and others 2016, doi 10.1007/s10648-015-9329-z
Nothing here is PROVEN: no machine can check how children learn. Early gains fade unless the child keeps learning after (Bailey and others 2017), so play together when you can.
