It is possible that your smartphone, despite being technically a "smartphone", will not be compatible with the FreeStyle Libre 2 sensor. ![]() The use of a CGM mobile app can make tracking your blood sugar levels more convenient, but there are some hurdles you'll need to overcome. The device also eliminates the need for a hand-held CGM receiver, thereby reducing costs. It makes sense to use the mobile app since most people always have their phones with them. ![]() The mobile app for your CGM will alleviate the burden of carrying around supplies while tracking your blood sugar levels throughout the day. One more thing to add to the list is carrying around diabetes "diaper bags" of supplies. Living with diabetes can be challenging, whether you're just learning the ropes or have been managing it for years. Staying in the range is likely to be easier with these apps. It's hard to imagine how FreeStyle Libre technology could disappoint those who still test their glucose with routine fingersticks2. Your FSL 2 readings can also be sent directly to your phone and you can view your data in real-time!Īpply the sensor to the back of your upper arm, scan it with your app, and you'll get your latest glucose value, including a trend arrow and an 8-hour historical graph of your glucose in response to food, exercise, and other factors. You can wear the FreeStyle Libre 2 CGM on the back of your arm or torso, sending your blood sugar readings to a hand-held monitor in real-time. It's now easier than ever to manage diabetes with CGMs since you can pair them directly with a compatible smartphone. Wearable CGMs measure blood sugar levels continuously throughout a 10- to 14-day period (depending on the device), and need to be applied once weekly (depending on the device). This is all second-hand information so far, gathered on the web.Managing diabetes has become easier with medical technology like insulin pumps and continuous glucose monitors (CGMs). Glimp can be connected to open-source app mentioned finding Libre sensors for sale with worldwide shipping on several sites: Freestyle Libre, $45, shipped worldwide The developers write that the Nexus 6P, Samsung Galaxy Core Prime, Samsung Galaxy Young and Samsung Galaxy may brick the sensor. Some specific Android phones may brick a sensor when using the Glimp app: this is mentioned by both the users and the developers. Some people write that the app gives results closer to a manual meter than the reader. The Glimp app gives slightly different readings from the Libre reader. Some people write that it is repeating the last 8 hours of its 14-day data after that, though. But the sensor keeps on broadcasting data longer and you can receive this data with a phone app. The life of the Libre sensor is limited (by software) to 14 days. The app can download, not only the last point of data on the Libre, but also every minute reading, for the past 12 hours. It is possible to use an app called Glimp to read the Libre sensor from your Android phone. If you use Glimp S for that, you can’t use a regular Libre reader afterwards. It is possible to initialize the sensor with an Android app called Glimp S, made by Italian developers (CTAPP Software). Prior to use, the sensor must be initialized, normally by the reader, so that it can start its 14-day life. ![]() ![]() NFC only works within 1.5" (4 cm): that’s how close you need to bring your phone to read the Libre sensor. For instance, you don’t get NFC in a Moto G5S+. In order to run an app to read the Libre sensor, your phone must have NFC enabled: not all Android phones do. Android and iOS phones both have NFC built-in, but Apple does not allow apps to use it (reserved for Apple Pay), so reading a Freestyle Libre sensor is only possible with an Android phone. It is possible to use the FreeStyle Libre without a reader, by using a phone app, for any phone that has NFC. Readers are locked into mg/dl or mmol/L, so, if you decide to purchase a reader, it is best to purchase one in a country which uses the unit you use. You can mix and match readers and sensors from any country. Many forum threads discuss it, so finding info is easy. I have looked into what it would take to use it. I am really interested in the Freestyle Libre, which is not available yet in the US.
