Abstract

Background: The One Drop | Mobile app supports manual and passive (via HealthKit and One Drop’s glucose meter) tracking of self-care and glycated hemoglobin A_1c (HbA_1c). Objective: We assessed the HbA_1c change of a sample of people with type 1 diabetes (T1D) or type 2 diabetes (T2D) using the One Drop | Mobile app on iPhone and Apple Watch, and tested relationships between self-care tracking with the app and HbA_1c change. Methods: In June 2017, we identified people with diabetes using the One Drop | Mobile app on iPhone and Apple Watch who entered two HbA_1c measurements in the app 60 to 365 days apart. We assessed the relationship between using the app and HbA_1c change. Results: Users had T1D (n=65) or T2D (n=191), were 22.7% (58/219) female, with diabetes for a mean 8.34 (SD 8.79) years, and tracked a mean 2176.35 (SD 3430.23) self-care activities between HbA_1c entries. There was a significant 1.36% or 14.9 mmol/mol HbA_1c reduction (F=62.60, P<.001) from the first (8.72%, 71.8 mmol/mol) to second HbA_1c (7.36%, 56.9 mmol/mol) measurement. Tracking carbohydrates was independently associated with greater HbA_1c improvement (all P<.01). Conclusions: Using One Drop | Mobile on iPhone and Apple Watch may favorably impact glycemic control.
