Stay ahead of diabetes with the smart continuous glucose monitoring (CGM) system.
Introducing the Guardian™ 4 smart CGM system featuring a new transmitter and sensor requiring no fingersticks for sensor glucose readings.* When the Guardian 4 CGM is applied to the skin, it uses a small sensor to measure sensor glucose levels every 5 minutes. Real-time readings are captured 24/7 and sent to a compatible mobile device via Bluetooth®** from a small wireless transmitter connected to the sensor, so you can see how you're doing anytime.
The Guardian mobile app is where you can view your sensor glucose, trends and log activities. The system also helps you know before you go high or low when predictive alerts are turned on. Choose when you want to be notified between 10-60 minutes in advance based on your preferred high and low range. You can select different options for alerts, such as maximizing the volume at night or muting all alerts when needed during the day.
When connected to Wi-Fi, the Guardian app can send your data to CareLink™ Personal diabetes management software, so you can see your personalized sensor glucose reports online and share them with select healthcare providers, family or friends. Those closest to you can even receive text messages whenever you go out of range.
To use the Guardian 4 system, you will need the Guardian 4 transmitter and the Guardian 4 sensor, as well as this app. The indicated age usage for the Guardian 4 system is ages 7+.
IMPORTANT NOTE: This app will only work with Guardian 4 transmitter, which was specifically designed to communicate with compatible mobile devices via Bluetooth. It will not connect to other Medtronic CGM transmitters, including the Guardian Connect and Guardian Link 3 transmitters.
The Guardian 4 system is made for people on insulin injections.

Guardian™ FAQ
Is Guardian™ free?
Yes, Guardian™ is completely free and it doesn't have any in-app purchases or subscriptions.
Is Guardian™ legit?
⚠️ The Guardian™ app has poor ratings and negative feedback. Users seem unsatisfied with its performance or features.
- For some reason I keep getting an alert when I open the app about the iOS version
- if the app is killed by iOS I need to wait a couple of minutes in order to get the last value
- the in-app alerts are horrible, who thought of having the alert cover the blood sugar value? Sometimes the alert just says something about not being able to connect to back end, I don’t care about that I want to read my blood sugar
- there are ZERO health integrations, why can’t you input the blood sugar alerts to the health app automatically and why can’t you read my workouts from there?
- why doesn’t this have an Apple Watch companion app??
Automatic logout
How do I disable the automatic logout? It’s one of the most annoying and useless feature I’ve ever seen.
Groaznică
O aplicație îngrozitoare. Chiar nu se poate optimiza, nu știți să o optimizați, sau așa doriți sa funcționeze?
The sensors are not working properly when when you're traveling abroad
I'm not sure if others are facing this, but whenever I travel abroad for 1-2 months, the sensors act up. They crash every 2-3 days and I find myself constantly changing or updating them until they eventually break.
Very poor at updating!
You are still very, very poor at updating the app with the latest IOS versions! I’m stuck at IOS 16.7 because I’m afraid of upgrading it to 17 version because it’s possible of not working!
Update for iOS 17
Sad that just a normal timely update to a new os warrants a review. But it is the first time the app has been updated and released on time with a major os release. Otherwise the same basic poorly integrated and slow working app. But it does the job... And again update released on time. Wow
Shame on Medtronic!!
The app never works up to date with my iPhone 12 software. That's why I'm forced to this compromise of keeping the phone locked on old and dangerously non-updated software. This lack of synchronization between the phone and the application is inadmissible and incredible!
The help I receive from the Blood Glucose Monitor is obliterated by the harm caused by this negligence of non-updating.
Update compatibility IOS 16.5
Please update Guardian 4 compatibility to IOS 16.5
More people i need this.
IOS 16
the program does not work on an iPhone, iOS version 16, iPhone 13 pro, please test it!! for me it’s vital..
FROM UKRAINE💔
Just the basics
So I used Dexcom in the past and I know their app and since I switched to Medtronic, I miss some functions that should be included in this app to make our life easier. So this app doesn’t have:
-integration with Apple Health
-integration with Siri
-SUPPORT FOR APPLE WATCH
I hope they will add these features to make our life much easier. Until then only 2 stars.
