CGM apps have become essential tools in diabetes management, offering real-time insights, alerts, and data-sharing features that enhance patient outcomes. But for MedTech developers aiming to push the boundaries of what’s possible, today’s capabilities are just the beginning.
In this article, we’ll explore the current CGM app landscape and what the future holds as apps grow smarter, more connected, and more predictive. We’ll also look at how platforms like Sequenex’s NEX can help developers build smarter, compliant, and future-ready solutions faster than ever.
Today’s CGM App Landscape
Today’s CGM apps serve as the digital backbone of continuous glucose monitoring, offering users and clinicians convenient access to real-time glucose data, trends, and analytics. These apps not only track glucose levels but also deliver alerts, enable data sharing, and support more informed treatment decisions. As CGM technology has become more widespread, CGM apps have evolved to offer a user-friendly experience with increasingly powerful features, making them indispensable tools for diabetes management.
The most popular CGM apps are typically developed by device manufacturers themselves. For example, Dexcom G7 offers a sleek, intuitive app experience that provides real-time glucose readings, customizable alerts, and Apple Watch integration. Dexcom Clarity, a companion app, focuses on long-term glucose trends and data visualization, providing valuable insights for both patients and providers. FreeStyle LibreLink, designed for use with Abbott’s FreeStyle Libre sensors, enables users to scan sensors with their smartphones for instant glucose readings. Medtronic’s MiniMed Mobile app supports real-time data display from their insulin pump and CGM systems, empowering users with remote access and alerts.
In addition to manufacturer-specific platforms, a range of independent CGM-compatible apps has emerged to enhance diabetes data management. Apps like mySugr, Tidepool, and Glooko integrate with various CGM systems to provide centralized data aggregation, advanced analytics, and AI-powered insights. These secondary apps often support data from insulin pumps, activity trackers, Apple Health, and food logs, offering a more holistic view of diabetes care.
Today’s CGM app landscape is diverse and expanding, with an increasing emphasis on usability, interoperability, and personalized insights.

- These systems may adjust recommendations based on historical behavior and preferences.
Automated Insulin Dosing Integration
- Integration with automated insulin delivery systems, like the Medtronic MiniMed 780G, allows some apps to not only monitor glucose levels but also adjust insulin doses in real time.
- These closed-loop systems are paving the way for more autonomous diabetes management.
Community and Social Features
- Some CGM apps offer built-in support communities or sharing options, creating a more engaging and connected user experience.
- Peer insights and shared stories can motivate users and reduce isolation.
Multi-Device Data Aggregation
- Some CGM apps, such as Tidepool, support importing data from a wide variety of CGM systems, insulin pumps, and activity trackers to provide a unified dashboard.
- This level of interoperability is especially useful for clinicians managing diverse patient populations.
Advanced Visualization Tools
- Certain apps offer dynamic charts and annotation features to make data interpretation easier and more meaningful for users.
- These tools are particularly valuable for healthcare providers seeking detailed reports and trend analyses.
These innovative features reflect a growing emphasis on personalization, automation, and actionable insights. For developers, exploring these unique capabilities can offer a competitive edge and open doors to improved patient outcomes.
What to Expect from Tomorrow’s CGM Apps
As continuous glucose monitoring technology evolves, the next generation of CGM applications is poised to deliver smarter, more personalized, and fully integrated diabetes care experiences. Driven by rapid advancements in biosensors, software development, and AI, tomorrow’s CGM apps will go far beyond monitoring—they’ll act as proactive health partners.
