Make, count, and discover numbers 1–10 together. Their First Numbers is a calm, completely free number-sense app for kids ages 2 to 4. It helps children understand what a quantity actually is — not simply recite “one, two, three.” A friendly duck introduces each number from 1 to 10 with its numeral, spoken name, and matching group of objects. Then six gentle activities let your child make the quantity, count it one object at a time, give one to each, add one more, choose the matching numeral, and find the number on a 1–10 path. WHAT’S INSIDE • Numbers 1–10, each introduced with a clear numeral, spoken number, and countable objects • Six calm, hands-on activities: Make, Count, One for Each, One More, Which Number?, and Number Path • Real number sense through making, counting, one-to-one correspondence, adding one, numeral recognition, and number order • Eight spoken languages: English, Latin American Spanish, French, Brazilian Portuguese, German, Italian, Korean, and Russian • A warm female voice for every language, with every number and instruction included offline • A beautiful pond world with a friendly duck and calm day and night modes • No reading required, no timers, no scores, and no pressure SCREEN TIME YOU CAN FEEL GOOD ABOUT • Completely free — no ads, in-app purchases, or subscriptions • No account or sign-in — nothing to set up and no email required • No tracking or analytics — your child’s progress stays on the device • Fully offline — play and listen in the car, on a plane, or at grandma’s house • No flashing rewards, guilt-driven streaks, or dark patterns FOR FAMILIES Their First Numbers is for toddlers meeting their first quantities, preschoolers building early math foundations, and families who want the same gentle experience across the languages spoken around them. BUILT BY PARENTS, FOR PARENTS We made Their First Numbers as a quiet, honest place for those first “how many?” moments — a sibling to Their First Words. No noise. No pressure. Just your child, a few numbers, and you. Free, forever. Open the pond and count together.
