What do … eat?

Features
Read full description

Every kid asks it sooner or later: "What does a lion eat? What does a whale eat? What does Grandma eat?" "What do … eat?" turns that question into a game. Your child types the name of an animal — or just says it out loud — and instantly sees a friendly picture list of everything it eats, with every answer read aloud in a warm, kid-friendly voice. Foods that are animals themselves are tappable, so kids can hop straight from lion to zebra to grass, following the food chain one curious tap at a time. Every animal they look up joins their own growing collection in the Gallery. WHAT'S INSIDE • Dozens of built-in animals with carefully curated, simplified diets and friendly flat-vector illustrations • Voice input and read-aloud, made for kids who can't type or read yet • Tap any food that's also an animal to keep exploring the food chain • A Discovery Gallery that collects every animal your child looks up • Ask about family members too — "What does Grandma eat?" always gets a playful answer • On-device AI fills in animals outside the built-in set, always clearly marked as AI-generated (needs an Apple Intelligence-capable device — the built-in animals work on every device) MADE BY PARENTS, FOR PARENTS "What do … eat?" is a family project — built by a mom-and-dad team and play-tested by our own son. Here's what that means for yours: • Completely free — no ads, no in-app purchases, no subscriptions • Collects no data at all and works fully offline, right on your child's device • A parental gate (a quick multiplication task) keeps little fingers out of Settings • Carefully curated facts, simplified for young learners — a fun start for curiosity, not a scientific reference • AI answers are always clearly labeled and may occasionally be a little silly or imprecise "What do … eat?" turns every car ride, zoo visit, and walk into a little food-chain adventure.
