Migo is a language playground built for kids aged 3 and up. Your child taps colorful cards, hears native speakers say each word, and plays games that make new languages feel like fun, not homework. WHAT YOUR CHILD WILL LEARN Migo teaches real, everyday vocabulary across five categories: Animals, Things, Food, Numbers, and more. Every word appears in two languages at once, so your child absorbs both their home language and a new one naturally. Choose from English, Spanish, and French, with many more languages on the way. No app update needed when new languages arrive. Just download and play. THREE WAYS TO PLAY Vocabulary Cards Tap any card to see a beautiful kawaii illustration, read the word in both languages, and hear it spoken by a native speaker. Over 100 words to discover. Where Is? A playful guessing game that asks your child to find the right picture. It reinforces vocabulary through repetition without feeling repetitive. Puzzles Gorgeous jigsaw puzzles with multiple difficulty levels (4, 6, or 12 pieces) and three visual styles. Perfect for building focus while having fun. WORKS WITHOUT INTERNET Download a language pack once and Migo works everywhere: planes, road trips, waiting rooms, anywhere your child needs something wonderful to do.

DESIGNED FOR EXPAT FAMILIES Migo was created for families living abroad. The vocabulary is chosen for real situations: making friends at the playground, ordering food, understanding the world around them. This is not a generic flashcard app. It is a companion for children finding their place in a new language.
