To evaluate the effect of mySugr^TM app on diabetes self-management, HbA1c level and its acceptability among app users with type 2 diabetes (T2DM).

A prospective, single-arm interventional study in 70 adult Filipino patients with T2DM and HbA1c ≥ 8.0%. Participants used the basic mySugr^TM mobile app for 12 weeks. The Modified Behavior Score Instrument and the Diabetes Self-Management Questionnaire (DSMQ) pre- and post-intervention measured its impact on diabetes self-management while the Mobile Application rating Scale (MARS) assessed the quality of the app.

There was a significant increased adherence to the diabetes self-care behaviors. DSMQ showed that only 12% of the participants had poor self-care behaviors at week 12 particularly in physical activity and diet. The baseline median HbA1c [9.55% (8.43-11.30)] and estimated HbA1c [8.9% (8.3-10.9)] declined significantly after week 12, [8.0% (8.0-8.43)] and [7.2% (6.5-8.1)] respectively with a very significant p value of (p < 0.00001). About 42% of patients achieved an HbA1c level of ≤7%. MARS confirmed the app’s good quality and acceptability.

Mobile application such as mySugr^TM mobile app can be a viable tool for improved self-care behavior and help in achieving good glycemic control among patients with poorly controlled T2DM even as early as 12 weeks. The app has good quality and acceptability.
