Can a smartphone app help tame diabetes? new study puts MoDD to the test
NCT ID NCT02021591
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested a web-based app called Mobile Diabetes Detective (MoDD) in 248 adults with type 2 diabetes. The app helps users identify problems with blood sugar control and suggests better behaviors. Researchers measured changes in blood sugar (HbA1c), problem-solving skills, and self-care over 12 months.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Mobile Diabetes Detective (MoDD) - a web-based app with SMS messages to help identify and solve diabetes management problems
- What this could lead to
- If it works, this could provide a scalable, low-cost tool to help people with type 2 diabetes better manage their blood sugar and daily self-care.
- What could go wrong
- This is a completed behavioral intervention study, not a drug trial. The app may not produce lasting improvements, and results may not apply to all diabetes patients.
