Chilli Koala: Learn & Explore
Languages, math, and science!
Free · Designed for iPad. Not verified for macOS.
Meet Chilli, a friendly AI koala who turns languages, math and science into play. Speak 15 languages, master numbers, explore science, with a buddy who is always kind.
Chilli Koala helps children and young adults learn languages, math, and science in a way that feels like play. Everything to learn, in one place.
Three learning pillars, one friendly AI koala buddy, and no ads anywhere.
TALK TIME: SPEAK 15 LANGUAGES
Practise out loud in Mandarin, Japanese, Korean, Spanish, French, German, Italian, Russian, Hindi, Arabic, Thai, Vietnamese, Malay, Filipino and English. Every language carries seven everyday scenarios, from saying hello to ordering at a food stall to talking about your family, plus four story missions where what your child says changes what happens next.
WORD GARDEN: VOCABULARY THAT STICKS
Twenty-two vocabulary packs with spaced repetition working quietly underneath. Words that prove hard come back sooner, words already known come back later. Listen to any word, flip the card to check yourself, and watch the garden fill up as words take root.
MATH ADVENTURE AND MATH LAB
Levelled arithmetic practice that keeps pace as your child improves, then step-by-step visual explainers for multiplication, division, fractions, decimals and units. The ideas that need showing rather than telling finally get shown.
SCIENCE EXPLORER
Eight topics covering animals, space, earth, the human body, insects, oceans, plants and weather, with forty discoveries to unlock through friendly quizzes built for curious minds.
CHAT WITH CHILLI
A kid-safe AI buddy for questions, encouragement and conversation practice. Replies are filtered and screened to stay age-appropriate, and there is no messaging with strangers anywhere in this app.
YOUR OWN KOALA TO RAISE
Chilli is a character your child looks after, not a mascot on a poster. Lessons earn experience, levels unlock new outfits, and returning day after day earns Chilli a new look. Feed, play, rest and dress up your koala between lessons.
DAILY ADVENTURE AND STREAKS
Each day opens with a short three-part adventure across language, math and science, sized for about fifteen minutes. Finishing it keeps a streak alive, and the streak changes how Chilli looks, so coming back tomorrow carries its own small reward instead of a warning about what you might lose.
MORE TO EXPLORE
Wordie word puzzles with a kid-safe dictionary, a daily journal for photos, voice notes and thoughts, an art studio, a memory game, typing practice, interactive stories where choices shape the ending, and achievements that mark real milestones rather than handing out trophies for showing up.

Chilli is properly drawn now! New character art across the home screen, the streak and the koala screen, where Chilli reacts to being fed, played with and put to bed.
Look after your koala. Open the wardrobe from beside the action buttons, rename Chilli by tapping his name, and see at a glance how caring and learning each help him grow.
Daily reminders at a time you choose. Turn them on in Account, App Settings, and pick the hour that suits your day.
Talk Time and Word Garden cards now fit on one screen, with a listen button and a hint that the card flips.
