The Booble app allows you to automatically measure the distance between the boules and the jack during a pétanque game. Its interface is extremely simple and intuitive: 1. The picture is taken automatically using the embedded bubble level. 2. One only has to touch the boules and the jack on the screen and the application will automatically – through advanced visual recognition algorithms used in the industry - locate them. 3. The ranking order appears in real-time. 4. If necessary, manual adjustments are possible: the boules rankings will then automatically and dynamically adjust. A zoom mode allows the user to validate the measurements' accuracy. The app allows up to 6 boules to be simultaneously measured. Booble is available in French, English and Spanish.
