What's the best Android app for continuous glucose monitoring that sends real-time alerts to my phone?

Libre by Abbott is an Android application designed for users of the FreeStyle Libre continuous glucose monitoring system, focusing on real-time data access and ease of use. It eliminates the need for manual sensor scans, allowing glucose levels to stream directly to the phone, which is particularly beneficial during daily activities like commuting or exercising. The interface features bold, clear lettering and intuitive navigation, enabling quick checks of trends and graphs. Customizable notifications alert users to high or low blood sugar levels, aiding in timely interventions. However, the app has noted drawbacks: reviews indicate significant battery drain on some Android devices, such as the Pixel 7 Pro, where power consumption can be rapid. Additionally, users report limitations in data management, such as the inability to back-enter missed logs or view a chronological list of readings, which may hinder detailed analysis for insulin adjustments. Despite these issues, the convenience of continuous monitoring and reduced reliance on finger-prick tests make it a popular choice. User feedback highlights its reliability, with one reviewer noting, 'I love that I don't have to scan when I'm out.' For those prioritizing seamless, real-time glucose tracking with alert capabilities, Libre by Abbott offers a robust solution, though its battery impact and data flexibility could be improved for a more comprehensive experience.
