Summary

The goal of this trial is to test a newly developed carbohydrate counting mobile application (named Petit Cactus) with photo recognition, for people with type 1 diabetes. To evaluate Petit Cactus, our objectives are: 1. To measure the association between app engagement and changes in blood glucose management over the same period. 2. To assess the usability of the app, focusing on engagement (i.e., frequency of meal logs) over 3 months and user satisfaction. 3. To validate the nutritional data obtained from the app's photo recognition algorithm by comparing it with a validated nutrient intake method (in this case, a web-based 24h recall).

Participants will submit their Ambulatory Glucose Profile (i.e., CGM data) at the beginning and at the end of 3 months, download the app to use for carbohydrate counting for the 3-month duration, complete a usability questionnaire at the end of 3 months, and complete an end-of-study interview to report on their satisfaction with the app.

  • Type1diabetes

Interventions

DEVICE

Petit Cactus

Access to the mobile application named Petit Cactus for 3 months to assist with carbohydrate counting in the context of type 1 diabetes using the following features: 1) Identify and log food items and estimate quantities through both photo recognition and manual selection from canadian food databases, 2) Automatically calculate and suggest the bolus insulin dose needed for a meal, based on the insulin-to-carbohydrate ratios entered in the settings and previously determined by the endocrinologist and healthcare team. 3) Track meals and different logged events (physical activity, stress levels, menstrual cycle...) and their impact on blood glucose levels.
