This category represents a more recent development, combining the portability and affordability of standard BGMs with the connectivity and data-sharing capabilities of modern smartphones. These meters connect to your smartphone via Bluetooth, and the corresponding app logs, stores, and displays glucose readings. Some models also offer features such as reminders, personalized insights, and the ability to share your data with healthcare providers.
| Feature | Description | Pros | Cons |
|---|---|---|---|
| Testing Method | Similar to standard BGM, results transferred to smartphone via app | Convenient, readings logged automatically, ability to share with care team | Dependent on the functionality of the smartphone, requires Bluetooth connectivity |
| Accuracy | Varies based on the device, mostly similar to traditional BGMs | User-friendly and easy to use with advanced options for monitoring | Additional learning curve for setting up the app and connectivity |
| Cost | Comparable to standard BGM with a small additional app feature | Modern and advanced, easy to use interface, automated logging and reminders | Possible issues with software updates and app compatibility |
| Data Storage | Typically stores readings in the associated app | Can provide insights, graphs, history that is useful for monitoring the condition and behavior | Smartphone battery drain, relies on constant charging of both meter and the mobile device |
Key Advantages: Smartphone-connected BGMs offer added convenience and insights. They remove the need for manual logging of results, as they are automatically stored and shared via the app, making diabetes management simpler. This kind of tracking can also create more data-driven management plans, as patterns in glucose trends become more easily apparent to the user and their physician. Key Disadvantages: The main drawback is their reliance on the functionality and battery life of the user’s smartphone. Issues with Bluetooth connectivity and software updates could interrupt monitoring.
Key Features to Consider
