About Guardian Monitor
Guardian Monitor shows glucose data from a supported CGM service on your iPhone, Apple Watch and widgets, with its own alarms that keep working in the background. It is built for the people doing the watching — a parent following a child, or anyone keeping an eye on someone close to them. The alarms are raised by your own phone, whatever the settings of the other person's system. Supported sources: Medtronic CareLink and Sibionics. You choose your provider when signing in. An account with that service is required, because Guardian Monitor reads your data through it. The app never changes any setting in the original service — it only displays what is already there. What it adds: • configurable alarms with your own thresholds, sounds and snooze, including a prediction alarm before a limit is reached and a warning when readings stop arriving • a background mode that keeps alarms reaching you even when the app is not open • spoken glucose readouts and Siri support • a full Apple Watch app with complications • a Live Activity on the Lock Screen, in the Dynamic Island, on the Apple Watch and in CarPlay • home screen and Lock Screen widgets • statistics with time in range over any period you choose • synchronisation with Apple Health and Nightscout (glucose, insulin, carbohydrates) • one sign-in for all of your devices What you see depends on the service you use. Sensor-only sources such as Sibionics report glucose alone, so insulin and meal information stays empty for them. Guardian Monitor is for informational purposes only and must not be used to make medical decisions. Always rely on your CGM manufacturer's own application and your healthcare team. Guardian Monitor is an independent application. It is not affiliated with, endorsed by, or connected to Medtronic or Sibionics. Guardian Monitor offers an optional auto-renewing subscription that unlocks alarms, the Apple Watch app, full 8-hour Live Activities, Apple Health and Nightscout synchronisation and spoken readouts. Everything else is free. Subscriptions are available as monthly or quarterly plans; the exact price for your region is shown in the app before purchase. The subscription is family shareable, so one purchase covers everyone in your Family Sharing group. Payment is charged to your Apple Account at confirmation. The subscription renews automatically unless cancelled at least 24 hours before the end of the current period, and your account is charged for renewal within 24 hours before the period ends. You can manage or cancel your subscription in your Apple Account settings after purchase.
