## Description

Guardian Monitor is a Chrome extension that displays CGM glucose data from supported services without modifying settings in the original app. It requires an account with the CGM service for authorization. The extension enhances standard functionality with a custom alarm system, voice readouts of glucose levels, and a standby background sound that turns into an alarm when needed.

It also supports Apple Health synchronization, Apple Watch (including eSIM models), Live Activity (CarPlay and Apple Watch), widgets, Siri integration, Nightscout synchronization, and session sharing between devices. Note: This app is for informational purposes only and should not be used to make medical decisions.

## Review summary

Users praise Guardian Monitor for watching glucose data on Apple Watch and for extending Medtronic pump visibility with rich graphs. However, the most recurring issues are login/2FA problems, data update delays (especially on the watch), and cross‑device session management challenges, with reliability sometimes dropping after updates.

### Pros

- Apple Watch integration provides real-time glucose data on the wrist.
- Allows remote monitoring of Medtronic 700/780g pumps, filling a gap left by official Medtronic apps.
- Rich data visualization including trend graphs and microbolus delivery details for deeper understanding.

### Cons

- Frequent login/authentication problems, including 2FA failures and password reset difficulties, with users being logged out on multiple devices.
- Inconsistent data updates with delays on the Apple Watch and occasional time/accuracy discrepancies.
- Session management issues across devices, where signing in on one device can log out or disconnect another.
