A learning app for children from age three, read in their parents' own voice

Piano from zero

The keyboard shows one octave at a time so each key is as wide as a small hand — a real piano key is 23 mm, too narrow for a three-year-old to hit. Every key sounds when touched, even a wrong one: that is how a child works out what a piano does. Each key carries the sung name Do Re Mi with the international letter C D E printed small underneath, so nothing has to be relearnt at a real piano. Beside the lessons there is free play across three octaves: no lesson, no stars.

Colouring and colour mixing

Thick, closed outlines, so a three-year-old's finger stays inside the lines. Pick a few colours, press Mix, and blue and yellow make green exactly as they do in a real paint box — then the new colour goes into that child's own paint box. Works with a finger, an Apple Pencil or an ordinary stylus.

Free drawing on blank paper

No outline to stay inside: a pencil to draw the shape, then a brush or a glitter pen to fill it. The sheet is twice the width of the screen — pinch to zoom, drag with two fingers to move around it, while one finger always draws. A shapes panel stamps a line, circle, square, triangle, star or heart for a child who cannot draw them freehand yet.

Dot-to-dot that fills itself

Drag a finger across the dot grid and it leaves a line; close the loop and the shape fills itself in the chosen colour — the quickest way for a child who cannot yet draw a straight line to end up with a tidy picture. Three dot densities, plus 100 guided puzzles from easy to hard: a window, a tent, a house, a fish, a sailing boat, a rocket, a dinosaur, a castle.

Playtime after lesson time

Finish a lesson and a sticker drops into the bag; enough lessons earn a play ticket. One ticket opens one round, and every round ends on its own, with no countdown clock for a child to watch. Seven games sit in one place: letter bubbles, colour catching, count-and-tap, glow drawing, plus mazes, number joins and flip cards. A Dino companion hatches from an egg and grows with the stars collected, then leads them back to the lessons when the tickets run out. Parents set how many lessons buy a ticket.

Mazes, number joins and flip cards

Three sets for thinking and memory, 100 levels each, getting harder as they go. Every maze has exactly one way out, and the grid grows with the child. Join the numbers traces 1–2–3 into a picture, with each number read aloud in Vietnamese, Japanese or English. Flip cards is pair-matching over 193 national flags, and a match says the country's name. All three live inside Playtime and open with a ticket, so lessons come first.

Handwriting in stroke order

A child traces the model strokes, then writes freehand. The app marks each stroke and points at the one to try again, so they know what went wrong without a parent leaning over. Capitals, lower case, tone marks, digits, the English letters A–Z and kana. The 22 Latin letters the Vietnamese and English alphabets have in common share one set of strokes, so an a is written the same way in either subject.

The Vietnamese alphabet and phonics

It starts at the alphabet board: 29 cards from Aa to Yy. Tap one and it says the sound of the letter, then an example word — “cờ … cá”. The letter on the card is drawn from the very same stroke data as the handwriting section, so the letter a child sees here and the letter they trace are one shape.

Then comes phonics, taught the way a classroom teacher does it: the child joins an onset to a rime and a tone while the app reads each step — tờ – oan – toan – sắc – toán. The c/k/q, g/gh and ng/ngh spelling rules are enforced right on the buttons, so nothing is learnt wrong from the start.

Hiragana and katakana

All 104 hiragana sounds including voiced and combined forms, plus the 46 katakana. Every character has its stroke order and is marked stroke by stroke, as in the Vietnamese section. Switch the interface to Japanese inside the app so the characters appear in their own context.

The kana alphabet board lays out all 104 hiragana and all 46 katakana, with one button in the title bar to swap between them. Tap a character to hear how it reads, then an example word — “a … あめ”.

English for a beginner

The alphabet board is 26 cards from Aa to Zz. Tap one and it says the name of the letter, then an example word — “ay … apple”. Each card carries an emoji for a child who cannot read yet, and a meaning line in whichever language the app is set to.

Counting runs 0–20, and each card says the same quantity three ways: the numeral, a row of countable dots set five to a line, and the English word. Handwriting covers A–Z in capitals and lower case, marked stroke by stroke as in the Vietnamese section. No grammar and no tests — this is the subject a child starts at.

JLPT vocabulary and grammar

The part for the older sibling: look up and learn Japanese words and sentence patterns from N5 to N1. Filter by level and 21 topics, search by word, reading or meaning. Every entry carries meanings in three languages, a translated example sentence and a speaker button for both the word and the sentence. Favourites and private notes sync with the account, and a 10-question quiz covers exactly the range on screen.

Maths and school readiness

Recognising numerals, counting, comparing, adding and subtracting within ten, and shapes — alongside reading and writing exercises from the school-readiness syllabus. Enough to start Grade 1 on familiar ground.

Listening to your child read

The child taps the microphone and reads back the syllable they built; the app praises them or invites another try. Recognition runs on that very device, so the child's voice goes nowhere. Off by default — turn it on when you think they are ready.
