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.

By far the best app to follow up on T1D (also for your children)
Great functionalities and updates
Cloud07
The app works great and offers many functionalities. The only thing I miss is setting different sounds for low or high alerts and to be able to see when an insuline stop has started and ended on the graph, those would be very handy additions!

How do you log i to this app. The screen is in russian and do not allow to create an account. Is this a bug?
Developer Response
The app doesn't create accounts of its own — it signs in to an existing CareLink account, which is set up on Medtronic's own service, not here. So there is no "create account" step in the app, and that part isn't a bug.The login page you see is CareLink's own page, and its language follows the server you select on the login screen, so picking the right region (EU for European accounts) should bring it up in the expected language.If you want to follow someone else's pump, they need to invite you in CareLink as a care partner — then you sign in here with that account and their data appears.
- A shield next to the reading shows when the pump is running in automatic mode.
- Extended alarm configuration with additional options.
- Fixed a snooze issue that could silence alarms until the app was restarted.
- Minor battery usage optimizations.
