This app is tailored for people with diabetes and is the first nutritional coaching application with optional sensors that is a molecular scan and a bluetooth weight scale. In real life situations, there are light interferences that can distort data. Therefore, we have calibrated it for a reasonable accuracy of the packets’ order labels generally + or -20% which is more precise. In any case, you will be notified if there is any abnormal percentage. We noticed a poor estimate of the food weights which is carried out by the user. Therefore, we have integrated the connected scale which helps in retrieving the food weight.
