About this app

An English teacher dad built Chubby Cat for his own daughter.
Your child speaks, the AI scores every sound, and a chubby cat teacher grows up with them as they learn.

WHAT KIDS DO
• AI pronunciation scoring: repeat a sentence and get a score instantly, with sound-by-sound (phoneme) feedback.
• Sentence building: tap scrambled words into the right order and learn English word order through play.
• Walk mode: explore 18 places, from the park and the mart to the beach and outer space, and name what you see in English.
• Chat with the cat teacher: press the mic, say something in English, and the cat answers at your child's level.
• Raise your cat: feed, play and care to level up your cat — a reason to open the app every day.
• Word collection, trophies and a paw-print calendar turn practice into a daily habit.

WHAT'S INSIDE
• 5,000+ English words and 7,400+ example sentences
• 37 topics including greetings, family, food, animals and school
• 5 app languages: Korean, English, Japanese, Traditional Chinese, Simplified Chinese

BUILT FOR PARENTS' PEACE OF MIND
• No ads.
• Parent dashboard: study time, completed lessons and pronunciation score trends.
• Parent mode is protected by a grown-up check.
• Separate child and parent profiles in one account.
• Your child's voice is used only for scoring and deleted right after.
• Designed around COPPA, with parental consent before starting.

START FREE
