1. Introduction

Continuous glucose monitoring (CGM) has genuinely revolutionized the way diabetes is managed by providing individuals with real-time glucose readings day and night, which has significantly improved their quality of life. CGM devices comprise a sensor that measures glucose levels in interstitial fluid, a transmitter that sends the readings to a receiver, and mobile applications that analyze the data and display trends. These apps have now become an integral part of using CGM devices. With the help of artificial intelligence (AI), the capabilities of CGM can be further enhanced to improve how diabetes is managed. This article reviews the scientific contributions behind mobile and AI innovations in CGM.

2. Early CGM Sensor Research

CGM sensors rely on glucose oxidase chemistry [1]

glucose + O2 → gluconic acid + H2 O2 (1)

Advancements in materials science have significantly contributed to improving the biocompatibility and lifespan of sensors, making them more reliable and efficient [2, 3]. Extensive clinical studies and trials have been conducted to ensure the safety and accuracy of CGM sensors, eventually leading to their approval by the FDA [4–6]. As a result, patients with diabetes can now rely on these sensors to provide accurate and real-time blood glucose readings, which is crucial in managing their condition effectively. The sensor technology advancements have revolutionized diabetes management, providing patients with a more convenient and reliable means of monitoring their glucose levels.

3. Alert Algorithm

With technological advancements, it is now possible to conduct real-time analysis on mobile devices [7]. This feat has been made possible through the use of efficient algorithms that enable quick processing of data. The ability to analyze data on mobile devices has opened up new possibilities in various fields, including medicine, finance, and research. With this capability, professionals can now access crucial data and insights on the go, leading to faster decision-making and increased productivity.

Encrypted protocols protected wireless transmission and cloud data [8, 9].

4. Mobile Apps for CGM Access and Analysis

Continuous Glucose Monitoring (CGM) has revolutionized how people with diabetes manage their blood sugar levels. Thanks to technological advances, CGM manufacturers have developed mobile applications that seamlessly connect to CGM devices via Bluetooth. These apps offer a range of features, including the ability to check glucose levels, trends, and graphs, all from the convenience of a smartphone or tablet. With CGM apps, people with diabetes can easily stay informed and in control of their health. Whether monitoring glucose levels during exercise, tracking trends throughout the day, or adjusting insulin dosages, CGM apps provide a wealth of information that can help improve diabetes management. With the ability to view real-time data on the go, CGM apps offer a new level of convenience and flexibility that was once unimaginable. So, to control your diabetes, consider incorporating a CGM device and app into your routine. Critical features of CGM apps include:

• Real-time glucose readings are updated every 5 minutes
• Visual display of glucose trends and patterns
• Customizable glucose target ranges and alerts for highs and lows
• Logging meals, insulin, exercise and health events
• Data sharing with caregivers and healthcare providers

Mobile applications are becoming increasingly popular because they provide users with easy access to continuous glucose monitoring (CGM) data. This allows individuals to make more informed decisions regarding their treatment options and to prevent hypo/hyperglycemia. Research has shown that mobile-connected CGM systems can reduce the time spent in hypoglycemia by up to 43% compared to traditional fingerstick monitoring [10]. In addition, these apps help users better understand how their daily behaviors impact their glucose levels, leading to improved overall control.

The Apple Watch has been leading the way in mobile continuous glucose monitoring (CGM) technology, providing a convenient way for users to quickly check their glucose status without taking out their iPhones. The watch can display glucose levels and alerts on the user’s wrist by pairing it with CGM sensors. According to a study conducted across multiple centers, Apple’s advanced algorithms provide up to 20 minutes of lead time in detecting critical glucose events, compared to relying solely on raw CGM sensor data [11]. This is a significant development in diabetes management, as it gives users more control over their glucose levels and can help prevent dangerous fluctuations.

5. AI for Detecting Patterns and Personalizing Insights

AI and machine learning techniques are applied to find hidden patterns in CGM data and generate personalized insights. For example, AI & ML can:

• Predict hypo and hyperglycemic events and provide advanced alerts to the user. AI models have shown an impressive accuracy rate of up to 81% in predicting hypoglycemic events 60–90 minutes before their occurrence, according to a study cited in [12].
• Detect how meals impact post-prandial glucose excursions. Machine learning analysis of CGM data has shown up to 90% accuracy in estimating meals’ carbohydrate content [13].
• Learn individualized insulin-glucose dynamics to recommend dosing. Closed-loop AI systems have significantly improved time-in-range compared to standard therapy [14].
• Discover behavioral and lifestyle factors influencing glucose variability. Studies utilizing AI on CGM data have uncovered that exercise, stress, and sleep are key factors affecting glycemic control [15].
• Provide personalized coaching and feedback based on an individual’s data patterns. Early research shows that AI coaching can improve adherence to glucose monitoring and health behaviors adherence [16].

With the help of Artificial Intelligence (AI), users can now uncover unique relationships hidden within Continuous Glucose Monitoring (CGM) data. By analyzing vast data, AI can provide actionable insights that guide therapy adjustments and self-management. As AI advances, more intelligent algorithms will optimize recommendations and insights over time, ensuring that users receive the most accurate and personalized guidance possible. This will empower individuals to make informed decisions about their health and lead to better outcomes in managing their condition. The potential impact of AI in this field is enormous, and we can expect to see continued advancements that will revolutionize how we approach diabetes management.

6. Conclusion
