The application calculates the ripeness of watermelons. How to choose a ripe watermelon? Very simple. You go to the market, pick your favorite watermelon, weigh it, and measure two circumferences of the watermelon - front to back and at the middle. (The scale is usually available at the marketplace, just bring a measuring tape with you). The app will determine the density and ripeness of the watermelon that you picked! It's a shame to pay money and buy a green watermelon. With the help of the application you will make the right choice. Real sweetness is guaranteed!
