The FreeStyle LibreLink app allows you to monitor your glucose with your iPhone.  Check your glucose by holding your iPhone near your FreeStyle Libre Sensor. The App is compatible with both 10-day and 14-day Sensors.
You can use the App to:
* Check your glucose with a painless scan, instead of a routine fingerstick 
* View your current glucose reading, trend arrow, and glucose history
* Add notes to track your food, insulin use, and exercise
* See glucose reports, including your Ambulatory Glucose Profile
* Connect to healthcare professionals with LibreView 
Compatibility may vary between phones and operating systems. Learn more about compatible phones at http://FreeStyleLibre.us
USING YOUR APP AND FREESTYLE LIBRE READER WITH THE SAME SENSOR
If you would like to use both the FreeStyle Libre Reader and the App with the same Sensor, you need to start the Sensor with the Reader first and then scan with your iPhone. Note that FreeStyle LibreLink and Readers do not share data with each other. For complete information on a device, scan your Sensor every 8 hours with that device; otherwise, your reports will not include all your data.
FreeStyle LibreLink is intended for measuring glucose levels in people with diabetes when used with a FreeStyle Libre Sensor. For more information on how to use FreeStyle LibreLink, refer to the User’s Manual, which can be accessed through the App.

 If you are using the FreeStyle LibreLink app, you must also have access to a blood glucose monitoring system as the App does not provide one. Fingersticks are required for treatment decisions when you see the Check Blood Glucose symbol, when symptoms do not match system readings, when you suspect readings may be inaccurate, or when you experience symptoms that may be due to high or low blood glucose.
 Use of the FreeStyle LibreLink app requires registration with the LibreView system, which is provided by Abbott and Newyu, Inc.

Ratings and Reviews
I hope I can change this review. I placed a monitor on my arm and waited 1 hour for the App to scan it. After one hour the App said “you need a new scanner”. I rescanned the sensor and I am waiting another hour. I am pretty sure it will say the same thing. Reading the reviews I see some messages saying that you have to do the first reading with some sort of reader (which I do not have). In any case, how stupid is that if true. I re-read the instruction on the sensor and there is no comment on that. In any case, why do I have to buy a reader? If this App is worth anything, why force people to buy a reader?
Update: I called and was sent a new one. I could activate with the phone only and it has been working for 2 days. My problem now is that the readings are all over the place. I understand that intersticial glucose is different from blood glucose, but I had 104 in the phone and 147 on the blood. Also there are some low readings like 66 that are totally off. I don’t even have diabetes or inject insulin (prediabetes). I will update. For now, I went from 1 to 2 stars.
Update 2: Day 3 is getting better. The values are less crazy and smaller differences from blood glucose. Increasing to 3 stars.

Interstitial fluid (ISF) glucose measurements will have a delay. ISF glucose and blood glucose measurements taken simultaneously are likely to be different. If you suspect your sensor is not working or is inaccurate, please call our customer care team at 1-855-632-8658.
Update (August 16, 2019): I’ve been using the app consistently for a while. It’s great and functions as intended - so no complaints there. One feature I would request that you have is the option to add a widget in the area accessible from the lock screen (without unlocking the phone). Here’s the idea: give me an instant-check widget that I (or anyone else) can get to without unlocking my iPhone. They don’t need full access to the app, but it should be enough for them to just use the widget and take a quick reading to make sure I’m not in the red, basically to do an instant blood-sugar level check without seeing any other info (like trends or logbooks). The only info the widget needs to display is the current blood-sugar level at the time of scanning (and a RED indicator if it’s too high or too low)... For more info, the phone should need to be unlocked.
Original review: I love this app. It’s not buggy at all, and actually feels like thought, time, and effort has been put into making it and polishing it out before release. So, thank you for not phoning it in. A few suggestions for the next version: Touch ID, Face ID, and/or passcode lock (at least the option to do so) would be nice. Also, since iPhones beyond the X models mostly use OLED panels (the XR being the exception), a “dark” theme is important, so please consider adding it as soon as possible. Not only does it not blind me in the dark, on some iPhone models, it may actually conserve battery life.

Thanks for your comment! As with any new technology, including mobile apps, Abbott is researching a wide variety of potential applications.
I actually have been a type 1 diabetic since I was 7 years old, I am now 25 and work for a family practice that deals with a lot of type 2 and type 1 diabetics. I have showed a lot of patients this product after I tested it out myself, and the doctors I work for have written a lot prescriptions for this item and have actually had me come into the room with them and the patient to inform them and show them how this product works. The doctors I work for have told me to contact the company for more information on insurance coverage, drug rep information to report back to patients and even becoming either a sponsor or something involved in this company because I truly do believe this will make any diabetics life easier as it has made mine. I work for a very busy practice and am very forgetful, this monitor has made my life that much easier and my Hemoglobin A1C come down from 9.2 to 7.8 within 3 months (this glucose monitor has a reminder setting that will alarm you within 1-2 hours to retest your blood sugar once you apply that setting) I highly recommend this product and can honestly say it has made managing my type 1 diabetes’s more reasonable.
