EkiYou-Study-2 : A National Multicentric Trial of the EkiYou Application for Insulin Bolus Calculation

Participants of the study must be adults treated with multiple daily insulin injections in a basal/bolus insulin regimen and users of a continuous glucose monitor (CGM). The study involves 3 visits (including the inclusion visit), for a total duration of 6 months for each participant. The study participants will be randomized in two groups and will receive EkiYou V2 either at inclusion or at the second visit after three-months control period. EkiYou V2 device is a new version of the previously CE-Marked device EkiYou V1. It is a decision support that include the following features to participants: * Carbohydrate counting through an extensive food database with more than 200k items. * Bolus calculation based on their meal, physical activity and blood glucose. * Bolus correction advice. * Long-acting insulin reminders and automatic periodic titration. * Insulin-to-carb ratios and correction factor automatic adjustment. * Connection to CGM devices Participants will also respond to ePRO questionnaires during the clinical investigation to collect data on their quality of life and their satisfaction.
