Libro & Libra: wireless scale and mobile app for personalized nutrition tracking (BALLERINA)

Today there are more and more people with special nutritional needs (e.g. people with food allergies and intolerances; athletes; pregnant and lactating women; patients with diabetes, hypertension, chronic kidney disease, phenylketonuria, etc.), who need to avoid or limit specific foods or nutrients in the diet. For this reason, information about foods and nutrients needs to be provided in a user-friendly way to become useful. Recently, advanced mobile apps based on artificial intelligence have been developed to provide this kind of information on the basis of food images taken by smartphones (e.g. Calorie mama, Bitesnap, etc.). However, they still struggle with the problem of the estimation of food quantities (volumes). Therefore, in the frame of Ballerina, the partners have developed a new product - based on the JSI’s pocket-sized BLE kitchen scale technology “Libra” - that enables accurate measurement of the food mass in real-time. To prove its efficiency, we connected it with Libro - a mobile app for advanced dietary analysis.
