Diabetes Apps: Tools You Can Use
How Diabetes Apps Help Prevent Type 2 Diabetes
Smartphone apps are proving to be powerful tools in helping individuals at high risk of type 2 diabetes make meaningful lifestyle changes. Research highlights how these apps promote weight loss and increased physical activity - two critical factors in diabetes prevention.
Results from Recent Studies
A recent systematic review and meta-analysis found that smartphone app interventions can significantly aid in weight loss. On average, participants using these apps lost 1.85 kg (about 4.1 pounds) and reduced their BMI by 0.90 compared to those in control groups. These outcomes align with findings from the Diabetes Prevention Program, which demonstrated a 58% reduction in diabetes incidence through lifestyle interventions, compared to a 31% reduction with metformin. Similarly, the NHS Diabetes Prevention Programme reported that, out of every 1,000 people referred, 127 developed type 2 diabetes within three years, compared to 154 in the control group - a 20% risk reduction.
Professor Jonathan Valabhji, NHS National Clinical Director for Diabetes and Obesity, emphasized the program's success:
"This important study is further evidence that the NHS is preventing type 2 diabetes and helping hundreds of thousands of people across England to lead healthier lives."
These results showcase how smartphone apps, when designed effectively, can encourage sustained behavioral changes that reduce diabetes risk.
How App Features Support Prevention
The effectiveness of diabetes prevention apps largely depends on their ability to engage users and promote long-term behavior changes. Personalization plays a crucial role - apps that tailor recommendations to individual preferences and needs are more likely to keep users engaged. Features like real-time activity tracking, dietary and weight monitoring, and targeted educational content provide users with actionable insights into how their daily choices impact their health.
Adding a human touch, such as personalized coaching through messages, calls, or video sessions, further enhances outcomes. Social networking features also create a sense of community, offering peer support that can motivate users to stay consistent. Research shows that apps with customizable options are more effective for weight loss, as they allow users to adapt the tool to their changing needs. In contrast, apps that rely on generic messaging often fail to maintain user interest over time.
Access and Cost Issues
Despite their potential, access and affordability remain significant barriers for many. Paid apps range from $0.99 to $29.99, with an average cost of $4.57, which can deter individuals with limited financial resources or low health literacy. The digital divide also limits adoption - while 91% of U.S. adults owned cell phones in 2013, only 55% had smartphones, with younger and higher-income individuals more likely to own these devices. Reliable internet access, particularly in rural areas, adds another layer of complexity. As Lisa Knoll, a lifestyle coach at Marshfield Clinic Health System, explained:
"We are a health system that cares for people in rural areas, so just because you have internet doesn't mean it's reliable or that it is fast."
Another challenge is user retention. Studies show that 76.4% of patients stop using diabetes apps shortly after downloading them, and platform preferences vary by demographic groups. For instance, African American users are more likely to use Android devices compared to white or Latino users. Paid apps often provide a better user experience with features like plain language, clear navigation, and intuitive design, which can improve engagement.
The COVID-19 pandemic has accelerated the adoption of digital health tools, pushing healthcare systems like Marshfield Clinic to adapt their diabetes prevention programs to virtual formats. However, this shift has introduced new challenges. Nancy Slizewski, DNP, Manager of Diabetes Care Management at Marshfield Clinic, noted:
"Perhaps the greatest challenge and barrier coaches have is not being able to see the participants. You pretend that you're looking at the participants."
While the road ahead has its obstacles, the growing body of evidence underscores the potential of diabetes prevention apps to make a real difference in reducing type 2 diabetes risk. As Chris Askew, Chief Executive of Diabetes UK, remarked:
"We're greatly encouraged by the results of this research, as the findings add to evidence showing many cases of type 2 diabetes can be delayed or prevented with the right support. It's clear the NHS Diabetes Prevention Programme can be a real turning point for people."
How Diabetes Apps Help Manage Existing Diabetes
Diabetes management apps make it easier to track blood sugar levels, manage medications, and maintain healthy habits. These tools can improve daily routines and lead to better long-term health outcomes.
Health Improvements and User Benefits
While diabetes apps can help prevent the condition, they are especially valuable for people already managing diabetes. Research shows that these apps can lead to better blood sugar control. For example, a meta-analysis of randomized controlled trials found that using diabetes apps led to an average HbA1c reduction of 0.49% compared to standard care alone. This reduction is a meaningful step forward for managing the condition.
In the January V2 study, 944 users were tracked over 14 days. Results showed that healthy users increased their Time in Range from 74.7% to 85.5%, while users with type 2 diabetes saw an improvement from 49.7% to 57.4%. Additionally, participants lost an average of 3.3 pounds over 33 days. Another analysis of 14 randomized controlled trials revealed that people with type 2 diabetes using apps experienced reductions in both body weight and waist circumference.
"This meta-analysis confirms that mobile health applications with practical technological functionalities and system architectures are beneficial in managing diabetes. These applications significantly reduced HbA1c levels and improved self-management behaviors." – Xinran Yu et al.
App Features That Work Best
What makes a diabetes app effective? The best apps combine features that simplify daily management and improve outcomes. For instance, apps with medication reminders have been shown to improve adherence in 85% of users over a 12-week period. Many apps also sync with Bluetooth-enabled glucose monitors, making blood sugar tracking easier by reducing the need for manual input. Tools like MySugr and OneTouch Reveal go a step further, offering features like carb counting, exercise tracking, and detailed reports.
Personalized feedback is another standout feature. Apps that tailor recommendations to individual data tend to outperform those with generic advice. For example, Glucose Buddy provides a 12-week diabetes education plan with quick, easy-to-understand lessons, some of which take just five minutes to complete.
Connectivity with healthcare providers also enhances app effectiveness. Apps that allow users to share data with their doctors and receive professional feedback improve adherence rates and overall engagement.
User satisfaction varies by app, but some stand out. MySugr has a 4.7 rating on iPhone and 4.4 on Android, while Glucose Buddy scores 4.8 on iPhone and 4.0 on Android.
Research Gaps and Study Limitations
Despite their potential, diabetes apps still face research challenges. Many studies focus on short-term outcomes, leaving questions about long-term user engagement unanswered. There’s also limited data on how well these tools integrate with broader healthcare systems or their cost-effectiveness. Additionally, most research centers on type 2 diabetes, with fewer studies exploring their impact on type 1 or gestational diabetes. These gaps highlight the need for more comprehensive research to better understand how digital tools can serve diverse diabetes populations.
Even with these limitations, healthcare professionals see the promise in these apps. Certified diabetes care and education specialist Lucille Hughes notes:
"My patients are more in touch with their diabetes. They're more engaged with their diabetes, and that's the ultimate goal." – Lucille Hughes
Important Features and Design Elements for Diabetes Apps
Research highlights several key features and design elements that are essential for effective diabetes management and prevention. The global market for digital diabetes management reached $11.8 billion in 2022, driven largely by the rising prevalence of diabetes. In 2021, 537 million adults worldwide were living with diabetes, a figure projected to climb to 783 million by 2045. This growing demand underscores the need for diabetes apps with impactful features.
Core App Features
Certain app features consistently contribute to better health outcomes. For instance, blood glucose monitoring and tracking is the most prevalent feature, found in 81.9% of diabetes apps studied. This functionality allows users to manually log their readings or link directly to Bluetooth-enabled glucose monitors.
Another critical feature is diabetes education and awareness tools, present in 55.8% of apps. These tools offer users quick lessons on managing blood sugar, understanding their medications, and recognizing symptoms. Additionally, 50.7% of apps include integration with measuring devices, while 40.6% feature medication adherence reminders.
| Feature | Percentage of Apps |
|---|---|
| Blood glucose monitoring and tracking | 81.9% |
| Diabetes awareness and education | 55.8% |
| Integration with measuring devices | 50.7% |
| Medication adherence reminders | 40.6% |
| Teleconsultation services | 37.7% |
| Risk factors tracking and management | 37.0% |
Teleconsultation services are available in 37.7% of apps, enabling users to consult healthcare providers remotely. This feature is especially useful for ongoing care, particularly when paired with secure data-sharing options.
Looking ahead, personalization and AI-driven insights are becoming increasingly important in diabetes app development. Apps that provide tailored recommendations based on individual data tend to perform better than those offering generic advice. However, many apps still struggle with user engagement and the quality of information provided.
Customizing Apps for Different Users
To be effective, diabetes apps must cater to diverse user groups with varying technological skills, backgrounds, and age-related needs. For instance, apps like DiaFriend have successfully incorporated features tailored to specific dietary habits, such as carbohydrate tracking for Portuguese cuisine.
Language accessibility is another key consideration. The Pregnant+ app, for example, offers multiple language options to broaden its reach.
Apps must also address varying levels of technological literacy. Many Americans lack reliable broadband access, so apps should be simple to navigate, featuring large icons, adjustable font sizes, and intuitive layouts. The SweetMama app stands out by providing educational resources designed for users with different health literacy levels.
To further enhance accessibility, apps should include adjustable interfaces and features like screen contrast options, step-by-step visual tutorials, and compatibility with voice commands or screen readers. These elements are particularly important for older adults and users with visual impairments.
While customization improves user engagement, it’s equally important to ensure robust privacy measures and seamless integration with healthcare systems.
Privacy and Healthcare System Integration
Data security remains one of the biggest challenges for diabetes apps. Alarmingly, 60% of these apps request permissions that could compromise user privacy, and 28.4% lack a dedicated privacy policy website. These gaps highlight the urgent need for stronger privacy practices.
HIPAA regulations primarily cover healthcare providers and insurers, leaving many app developers outside its jurisdiction. In 2022, a U.S. company faced a €45,000 fine from the Italian Data Protection Authority after an employee mistakenly shared personal data from 2,000 glucose monitoring app users during an email campaign.
To address such risks, developers should adopt best practices like obtaining informed consent before collecting personal health data, clearly explaining how that data will be used, and allowing users to revoke consent at any time. Certifications like SOC2 and HiTrust can also help ensure high security standards.
Integration with healthcare systems is another critical area. For instance, the Shanghai Municipal Health Commission collaborated with Wanda Company to create a diabetes care app that connects patients to local healthcare providers using electronic health records. Wanda provided the technical expertise for development and maintenance, demonstrating the potential of public–private partnerships.
Privacy concerns remain a significant barrier to adoption. A 2010 survey by the California Health Care Foundation found that 66% of adults were worried about the privacy of their medical information. Apps that successfully integrate with healthcare systems often include secure data-sharing features, appointment scheduling, and professional feedback on user-generated health data. These capabilities bridge the gap between self-management and professional care, creating a more comprehensive approach to diabetes management.
These principles lay the groundwork for evaluating how digital and in-person diabetes programs compare within the U.S. healthcare system.

Digital vs In-Person Diabetes Programs
With 97.6 million U.S. adults living with prediabetes, healthcare systems face a monumental challenge in providing adequate care. Complicating matters further, there’s only one DPP center for every 45,000 adults with prediabetes, leaving rural areas especially underserved - 15% of counties offer DPPs compared to 50% in urban areas. Digital diabetes programs are stepping in to bridge this gap, sparking a debate on how they compare to traditional in-person programs.
Comparing Results Between Digital and In-Person Programs
Studies show that digital diabetes prevention programs (dDPPs) achieve outcomes similar to in-person programs, with added benefits like greater accessibility and lower costs. For example, one study found no significant differences in weight loss percentage or physical activity levels between digital and in-person participants, both achieving the recommended 4.7% weight loss.
Stanford University’s diabetes self-management education program also found that digital programs were as effective as in-person sessions in reducing blood sugar levels and alleviating depression. This is a critical finding since depression often complicates diabetes management.
| Program Aspect | Digital Programs | In-Person Programs |
|---|---|---|
| Accessibility | Available anytime, anywhere | Limited by schedules and location |
| Cost per Participant | $571 average program cost | Higher due to facility and staff expenses |
| Net Healthcare Savings | $598 saved per participant in Year 1 | $2,277–$3,070 saved over 2–3 years |
| Weight Loss Achievement | 4.7% or better | 4.7% or better |
| Retention Rates | Potential advantages | Traditional completion rates |
| Coverage Area | Nationwide reach | Restricted to local areas |
The cost-effectiveness of digital programs is particularly striking. For instance, participants in digital DPPs reduced all-cause healthcare spending by $1,169 per person, with $699 of those savings coming from reduced inpatient care. After accounting for the average program cost of $571, this translates to $598 in net savings per participant in the first year.
However, not all digital solutions are equally effective. The Peterson Health Technology Institute (PHTI) reported that some diabetes apps offer limited clinical benefits, with HbA1c reductions ranging from 0.23 to 0.60 percentage points - results that do not always justify the extra costs.
"If health plans or employers are going to be paying extra for these solutions, they have to deliver extra benefit clinically above and beyond what a patient would expect in 'usual care'", said Caroline Pearson, executive director of PHTI.
Despite these concerns, the PHTI identified Virta Health as a standout example, citing its success in reversing Type 2 diabetes through personalized nutrition and remote care. This highlights that well-designed digital programs can indeed deliver meaningful outcomes.
How Digital Programs Fit U.S. Healthcare
The scale of the diabetes epidemic underscores the need for digital solutions. Currently, 15.8% of U.S. adults are affected by diabetes, with 11.3% diagnosed and 4.5% undiagnosed. Traditional healthcare systems simply cannot meet the demand for in-person services alone.
A great example of digital integration is the Montana Diabetes Digital Health Learning Network. This initiative, a partnership between the Montana Diabetes Program, the CDC, and other organizations, used the BlueStar® digital health platform to support 198 patients with Type 1 or Type 2 diabetes. The program allowed 11 diabetes care specialists to remotely monitor patients, leading to improvements in blood sugar, blood pressure, and weight.
"Digital health gives visibility to population health data enabling remote monitoring capability, enabling true person-centered care for populations at scale (one-to-one to one-to-many)", researchers noted.
Digital programs have also seen a surge in enrollment since 2015, thanks to widespread smartphone adoption among 81% of U.S. adults. Unlike in-person programs, digital options offer unmatched flexibility, allowing for personalized approaches tailored to individual needs and preferences.
AI-powered tools are another promising development. One study showed that 77% of participants using AI-coaching tools achieved significant weight loss, with an average weight reduction of 4.8% of body weight and a 7 mmHg drop in systolic blood pressure.
"AI democratizes access to diabetes management best practices in a manner that fits into a person's 'life-flow' and a healthcare provider's workflow", researchers explained.
Despite their advantages, digital programs face challenges in implementation. Healthcare organizations must ensure robust support systems, educate users about data ownership and privacy, and adapt workflows to incorporate continuous, data-driven care. Transitioning to digital-first models also requires rethinking payment structures to sustain these programs.
Both digital and in-person diabetes programs have unique strengths. Digital solutions excel in accessibility and affordability, while traditional programs maintain their value for those who prefer face-to-face interaction. As the healthcare system shifts toward value-based care, a combined approach may offer the best path forward for diabetes prevention and management in the United States.
Conclusion
Diabetes apps are showing real potential in both preventing and managing diabetes in the United States. With over 30 million Americans living with diabetes, the disease ranks as the seventh leading cause of death and costs the nation more than $322 billion annually.
Research highlights their benefits: users of diabetes apps have seen an average weight loss of 4.1 pounds and a 0.90-point drop in BMI. They’ve also improved diabetes management outcomes - like WellDoc's BlueStar, which reduced A1C levels by 1.9 percentage points in 12 months compared to 0.7 points in the control group.
Interest in these tools is growing. About 35% of people already use mobile health apps for diabetes self-management, and 57% are open to trying them in the future. This growing adoption signals a real opportunity for digital solutions to make a broader impact.
Besides improving health outcomes, these apps offer cost-saving advantages. But challenges remain. For instance, only half of diabetes patients achieve their target A1C levels (below 7.0%), while nearly 15% face dangerously high levels (A1C above 9.0%). Although many apps show promise in lowering HbA1c, more rigorous, long-term studies are needed - especially to explore their role in preventing diabetes for those with prediabetes.
Engagement is another hurdle. Mobile health interventions see a 43% dropout rate, and user satisfaction ratings vary widely, from 38% to 80%. This highlights the importance of focusing on user-friendly designs and strategies to keep people engaged.
Artificial intelligence may hold the key to the next wave of advancements. AI-driven glucose monitoring apps have already helped users achieve better glucose control, with healthy individuals increasing their time in the optimal range from 74.7% to 85.5%, and those with type 2 diabetes improving from 49.7% to 57.4%. These personalized tools could pave the way for more tailored and effective care.
Looking ahead, the focus must be on conducting higher-quality research with longer follow-up periods, designing apps that prioritize user needs, and integrating these tools more effectively into healthcare systems. Additionally, more studies are needed to understand how these apps can help prevent diabetes in people with prediabetes.
