What they did
Two-arm RCT randomized 72 adults with type 1 diabetes to Glucose Buddy smartphone self-management plus weekly CDE text feedback versus usual care, with outcomes to 9 months.
What they found
App plus feedback produced a significant HbA1c decrease versus usual care; usage frequency did not clearly mediate the HbA1c change.
The limits
What it doesn't show
Whether app alone without CDE texts works, long-term durability beyond the trial, or QoL gains despite better glycemia.
