Does your child suddenly "feel full" after two bites of broccoli but magically has room for dessert? Tummy Meter is the silly, science-y app that might save your sanity — with a fake tummy scan. Made by a parent, for parents — because the hard days of raising a picky eater deserve at least one tool that asks nothing in return. How it works 1. Place the phone gently on your child's tummy 2. Press the big scan button 3. Watch the machine whir to life. It beeps, it fake scans, and it delivers an official verdict: exactly how full their tummy is — and how many more bites they need to reach 100%. Completely free. No ads. No sign-up. No data collected. For entertainment only. Tummy Meter is designed to make mealtimes a little more fun. It does not measure anything real. Results are randomly generated for entertainment purposes. It works entirely on your device. Nothing is sent anywhere. No account needed. Just open it and scan.
