"I'm full." "I'm not hungry." "I don't want to eat." Sound familiar? Every parent knows the mealtime struggle. You've made the food, set the table, and your kid has taken two bites of rice and declared they're done. You know they're not full. They know they're not full. But try convincing a 4-year-old of that. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ What if your phone could settle the argument? Tummy Scanner turns your phone into a "tummy fullness detector." Your child places the phone on their tummy, watches a real-time scanning animation, and gets a scientific-looking percentage of how full they are. "Only 27%? I need to eat more!" That's the magic. The result comes from *you*, not from an argument. An invisible slider lets you secretly set the number before the scan completes. Your child sees science. You get peace at dinner. **How it works:** - A convincing scanning animation with haptic feedback. - You secretly control the result with a hidden slider - Kids see a percentage they actually believe - Tap on organs to learn about digestion (Mouth, Stomach, Intestines, and more) Why parents love it: No more "eat three more bites" negotiations Kids *ask* to be scanned — they're excited, not resistant Works at home, at restaurants, at grandma's house Sneaky onboarding teaches you the trick without kids seeing **A note on the magic:** The "Top Secret" page in setup explains everything to grown-ups. Just don't let little eyes see it. No accounts. No ads. No data collection. No internet required. Less than a dollar / month — cheaper than the food they leave on the plate.
