Carbohydrate Counting and Bolus Calculator Mobile Application Improves Time in Range in Adults With Type 1 Diabetes

The control group followed a standard diabetic habitual diet

"Eligible participants provided informed consent and underwent baseline assessments, including demographics, medical history, insulin doses, and fasting blood samples for HbA1c and lipid profile. Participants used the FreeStyle Libre 2 sensor, with AGP data collected bimonthly. The primary outcome was Time in Range (TIR, 70-180 mg/dL), while secondary outcomes included TAR, TBR, GV%, GMI, HbA1c, and BMI.~A registered dietitian provided structured CHOC-BC education. The intervention group used the CHOC-BC app, validated against expert-calculated carbohydrate counts, while the control group followed standard diabetes education. Virtual follow-ups occurred bimonthly for three months. At study completion, HbA1c, lipid profile, insulin doses, weight, and AGP data were collected for comparison."
