EkiYou-Study-1 is an interventional before/after clinical investigation according to EU 2017/745. It is conducted in 21 adults with diabetes and treated by multiple daily insulin injections. After a run-in period of 2 weeks, participants will receive for 6 weeks EkiYou V2 application that will help them to estimate their daily bolus and basal insulin doses. This device weekly adjusts insulin parameters including : basal insulin dose, insulin to carb ratios and correction factor. The aim of the study is to assess the safety and performance of EkiYou V2 device. Data on glycemic control, safety, quality of life and satisfaction of participants will be collected.
Participants of the study must be adults treated by multiple daily insulin injection in a basal/bolus insulin schema and users of a continuous glucose monitor (CGM). The study involves 5 visits, each two weeks. Participants will be included for 8 weeks divided in two distinct periods : * Run-in period for two weeks to collect glycemic control at baseline with their standard insulin management * Intervention period for 6 weeks where participant will receive the investigational device EkiYou V2 to manage their insulin injection. 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.

Diabetes Treatment Satisfaction Questionnaire (DTSQ)
Quality of life associated with diabetes questionnaire. Treatment Satisfaction: Items 1, 4, 5, 6, 7 \& 8 are summed to produce a Treatment Satisfaction score (range: 0 to 36). The higher the score, the greater the satisfaction with treatment. Individual satisfaction with treatment items (items 1, 4, 5, 6, 7 \& 8) can be considered separately: All rated: 6 (very satisfied, convenient, flexible, etc.) to 0 (very dissatisfied, inconvenient, inflexible, etc.). The higher the score, the greater the satisfaction with each aspect of treatment. 'Perceived frequency of hyperglycaemia' (item 2) \& 'Perceived frequency of hypoglycaemia' (item 3): Both rated: 6 ('most of the time') to 0 ('none of the time'). Here, lower scores indicate blood glucose levels closer to the ideal. Higher scores indicate problems

Hypoglycemia Fear Survey 2 (HFS II)
Fear of hypoglycemia questionnaire. Behavioral Subscale, Items: 1-15 Score Range: 0 to 75. Higher scores indicate more frequent behaviors aimed at avoiding hypoglycemia, reflecting a greater fear of low blood sugar episodes. Worry Subscale, Items: 16-33 Score Range: 0 to 90. Higher scores suggest greater concern or anxiety about the consequences of hypoglycemia, including physical symptoms and impact on daily activities. Total Score Range: 0 to 165 (sum of both subscales). A higher total score indicates a more intense overall fear of hypoglycemia, affecting both behavior and emotional well-being.
