Learning together — four apps, just open and play
These four apps were built for two children at home, then opened up for every family
to use. No sign-up, no ads, no fees and nothing collected from your child — the results
stay on your child's own device.
Please note: the apps themselves are in Vietnamese, since they were written for
children learning the Vietnamese primary-school curriculum.
Maths for Grade 1
Adding and subtracting up to 100, shapes, telling the time. Correct answers earn gems to trade for pets and hats.
Grade 1 · ages 6–7Maths for Grade 3
Multiplication and division, fractions, perimeter and area, word problems. With rewards, a collection and rising levels.
Grade 3 · ages 8–9Computer Basics
Questions about computers, the internet and staying safe online — learning to keep your own information private.
Primary · ages 8–11Space Chess
Chess from the very first move, level by level. Several board colours and two save slots for two children.
Ages 6+ · complete beginnersWhy we do not charge for this
There is no login box here, no buy button, and nowhere that asks for your phone number. We built these for our own children first, so the only thing we want back is that a child learns something. If you find them useful, please pass them on to another family.
