Mathmellow

Arthur's Lab

About this app

Mathmellow is a calm, pressure-free way for children aged 4 to 10 to practise maths.

No timers. No countdowns. No "game over". A wrong answer simply wiggles gently and waits — your child tries again whenever they are ready. Confidence first; speed never.

★ COMPLETELY FREE, GENUINELY PRIVATE
• No adverts of any kind
• No in-app purchases, ever
• No accounts, no sign-in, no email address
• No analytics, no tracking, no data collection
• No internet connection needed — the app makes no network calls at all
Everything your child does stays on your device.

★ EIGHT ACTIVITIES, ONE TAP APART
• Count — how many dots (or apples, strawberries, bananas)?
• Find — which group shows this number?
• Adding, Subtracting, Times and Dividing — one ordered table per level
• Mixed — every question is a different operation
• Missing number — 14 + ? = 28

★ BUILT AROUND HOW CHILDREN ACTUALLY LEARN
• Quantities appear in rows of five, so children learn to see "five and some more" instead of counting one by one
• Tables run in order, which builds pattern recognition and counting on. A "mix it up" switch shuffles them for older children who need recall practice
• Fix-ups quietly collects the questions your child got wrong and replays only those, until every one is cleared

★ UP TO FOUR CHILDREN, EACH WITH THEIR OWN PROGRESS
Every child gets their own name, avatar, age, levels, treat jar and fix-ups list. Their age sets the difficulty and decides which activities appear: younger children get counting and number-finding, older ones get mixed operations and missing numbers.

★ A CALM SPOKEN VOICE, IN NINE LANGUAGES
English, Română, Français, Deutsch, Español, Italiano, Polski, Nederlands and Português. Pick the voice from the ones installed on your device — and hear it before you choose.

★ GROWN-UP CONTROLS (behind a maths question children cannot answer)
Voice and language · sound effects · dots or fruit · shuffle tables · answer choices (2, 3 or 4) · age for each child · reward treats (sweets or fruit) · reset levels · empty the jar.

★ REWARDS THAT ARE JUST REWARDS
Finish a level and choose a treat for the jar. No streaks to protect, no nagging notifications, nothing to buy. Grown-ups can switch the rewards to fruit.

Landscape. Offline. Free. Made for children — not for advertisers.
