I am sure Libre 3 has got the attention of all the people who have high blood glucose levels. Libre 3 is a powerful tool to stay updated on your glucose levels using your smart watch. However, does it work with the Apple Watch?
Since I have a few family members who have high glucose, I have checked the Libre 3 app. Unfortunately, without a companion app, you can’t get any insights into your health with your Apple Watch.
Needless to say, you can still make it work with your iPhone, but it does involve a little bit of hassle. What is it, and how can you overcome it? Here I will tell you everything you need to know about Libre 3 and Apple Watch companionship.
How To Make Libre 3 Work With Apple Watch
The FreeStyle Libre 3 measures glucose levels using a sensor placed on the skin and via the Libre 3 app. Because the Apple Watch does not support glucose monitoring, nor does it have a built-in sensor for the same (as of 2025), the app does not work on the Apple Watch.
Another thing to note is that to view readings on your Apple Watch, you need to download third-party apps on your Apple Watch and iPhone. Apps like Glucowatch, LibreLinkUp, Sugarmate, or others, connect to Apple Health and mirror data from your iPhone.
Benefits of Using Libre 3 With Apple Watch
Get Real-Time Statistics
If your Libre 3 app is paired with a companion app on your Apple Watch, then you get real-time statistics. These real-time readings are very helpful in helping you plan your day. Libre 3 also comes with graphs and charts to make it easier for even beginners to understand.
Although I have observed that, based on your physical activity, there can be a lag in the statistics, it is only a matter of 5 minutes. After 5 minutes, you will be presented with accurate readings of your glucose level in real time to take the necessary actions.
Stay Updated About Your Health
If there is a sudden spike in your glucose levels, then you will be notified about it through the Libre 3 app. These alerts are very helpful because they help regulate your actions based on results.
Even if you miss your doctor appointments (which I don’t recommend), you can still be aware of your health just by checking your readings on your wrist.
Choose A Healthy Lifestyle
Overall, with all of this information, you can pick a healthy lifestyle. A healthy lifestyle is a must in today’s time, where there is so much pollution and nothing organic to consume. With the right insights from my Libre 3 app, you can plan diets and exercises for you and your family members.
Like I was never aware that certain medications, activities, and illnesses can lead to glucose spikes as well, whenever I am dehydrated, my glucose level is affected. With the Libre 3 app, I have been aware of all of this, which helps me plan a better lifestyle without facing harsh consequences.
Bottom Line
Libre 3 is one of the most trusted apps out there for glucose readings. It has a high accuracy record. Although I have heard cases where the reading was false, this news was quickly dismissed after revealing that there was poor finger placement.
Other factors, like apps not updated, older versions of OS, and bugs, can create issues. However, keeping technicalities aside, Libre 3 should work appropriately without giving any false results. With all that said, it should be noted that at the end of the day, regular visits to your doctor are a must.
If I were facing severe complications, then I would trust a doctor any day over any app. Libre 3 is a good way to be the master of your own destiny and stay aware of your well-being. However, if your symptoms say otherwise, then consult a doctor right away.
