Smartphone app shows little effect on physical activity in type 2 diabetes
Last updated July 8, 2026
Key finding
We found no significant effect of the intervention on MVPA at 3 months (β=1.51, 95% CI -5.53 to 8.55).
This study evaluated the impact of the DiaCert smartphone app on physical activity levels in adults with Type 2 diabetes. Results indicated no significant improvements in moderate to vigorous physical activity or other health metrics.

Plain-language summary
What this paper says
A plain-language read of the study’s main message and where it applies.
Study focus
This study evaluated the impact of the DiaCert smartphone app on physical activity levels in adults with Type 2 diabetes. Results indicated no significant improvements in moderate to vigorous physical activity or other health metrics.
Clinical relevance
Understanding the effectiveness of mHealth interventions like the DiaCert app is crucial for developing strategies to improve physical activity in adults with Type 2 diabetes. Given the rising prevalence of diabetes, identifying effective tools to promote lifestyle changes is essential for enhancing patient care and health outcomes.
Keep in mind
The study did not show significant improvements in primary outcomes. The sample size and demographic characteristics may limit generalizability. Potential unmeasured confounders could affect the results.

Evidence Suggest
- No significant effect on MVPA at 3 months (1.51 minutes/day, p=0.45).
- No significant effect on MVPA at 6 months (-3.53 minutes/day, p=0.45).
- BMI showed a slight increase (0.52 kg/m²) but lacked meaningful group differences.
Who this applies to
- Adults aged 18 and older with Type 2 diabetes.
- Individuals seeking to increase physical activity through mobile health interventions.
Keep in Mind
- The findings may not apply to populations outside the study sample.
- The lack of significant results suggests the app may not be effective for promoting physical activity.
- Further research is needed to explore other mHealth solutions for diabetes management.
Between the Lines
- The study did not show significant improvements in primary outcomes.
- The sample size and demographic characteristics may limit generalizability.
- Potential unmeasured confounders could affect the results.
