What's the best Android app for continuous glucose monitoring with customizable alerts?

Dexcom G7 is an Android application that pairs with the Dexcom G7 continuous glucose monitor (CGM) sensor, providing real-time glucose data every five minutes for individuals managing diabetes. The app's core functionality includes a clear display of current readings, trend arrows, and a history log, which is essential for tracking glucose patterns over time. Users report high sensor accuracy within 36 hours and reliable adhesion even in hot climates, making it suitable for active lifestyles. Alert customization is a standout feature, allowing users to set thresholds for hypoglycemia and hyperglycemia, critical for nocturnal safety. However, reviews indicate that alert volumes lack device-specific profiles, which can be intrusive when using earbuds. Another limitation is the app's failure to auto-restart after phone reboots, potentially interrupting monitoring during OS updates. Dexcom addresses compatibility with in-app warnings for new Android versions, though feedback suggests these notifications could be timelier. For daily use, the app balances precise monitoring with practical tools, offering a reliable solution despite minor issues in automation and alert granularity.
