TUMMYGOTCHI is a playful children's nutrition app where a pixel-art gut microbe character lives in your kid's belly and reacts to what they eat. Kids snap a photo of their meal, AI reads the ingredients, and TUMMYGOTCHI responds in character — then a collectible poop creature bursts out based on how well they ate, with parents getting a cheerful notification. The science of gut health is delivered entirely through the weird, emotional voice of the character rather than lectures, turning healthy eating into a game kids actually want to play.
