Review: Installing the app - If this sensor is useful or not, I will never know... because I could not get it to work. To apply the sensor to the arm is easy and you will not feel a thing. To install the app is a total different issue. I have a Samsung Phone and I use this phone exactly for the reason intended by Alexander Graham Bell and nothing else... like most seniors my age. I do not care one bit for all this nonsense and pretend functionality on a modern phone. Actually most phones are virtually unusable because the keyboard is too small for old fingers. But I did managed to "register" for a Google account. They of course ask me all sorts of questions which are none of their damn business... but I suffer with dignity so I go to the Google Play Store and search for "Lingo" and installed the app. The app started with asking me all sorts of questions... again, none of their business. I paid for the sensor so I should be able to use it, but no... they are more interested in my info. Then 10 or 20 pages later (i did not count) finally the page which read: Ready To Scan... I did hold the back of my phone directly onto the sensor which I had already put onto my arm. and .... nothing... then the message... Pairing Error... I tried numerous times Then I called the support line and as expected a gentleman with a heavy indian accent ( you recognize the accent when they call you and try to con you out of your money, never pick up the phone when you do not recognize the number). Obviously the guy talks too fast, uses unnecessary words and you cannot understand a thing. This went on for good 1 hour and nothing. among other things, he asked me to delete the app, reinstall this and then search for a red dot... ??? what red dot??? I still do not know what he meant. Anyway I told him, that I cut my losses and tell everybody about my ordeal. Then he suddenly offered me to replace the sensor. Very well I am down $50 already, might as well... arrives in 2-3 days, meaning 4-5 days because of the weekend. Why is there no "app" for this sensor on a PC. After all A PC has a screen I can actually see and a keyboard which does not require baby fingers. And for Pete's sake, do not ask me all these dumb questions, which are none of your business. If the replacements ensor works, I will try it... but then never again. Simply measure your morning fasting BG like before and that is that. Minute to minute updates are superfluous and expensive technology and a pain in the rear. 12/21/25 1:14pm Important update. I did not want to wait for the replacement and ordered another one yesterday from desertcart same day delivery. This one worked, but did not give me any reading for 1 hour and afterwards it was 20 points too low compare to the finger stick (73, 92). however this morning it was a lot better, In fact just now it reads 92 and the contour next fingerstick reads 95. I am more than happy with that. To be sure I get some benefit from this device... after all I learned that overnight my BG dropped to 55 for a brief moment... I seriously doubt that. All you can see trends, and I am lucky with this one, it is even accurate.... but I am an EE and I did work with large continuous datasets which were contaminated with large random errors and judging by the graph, it looks very much like a data set processed using a Markov Process. This is a mathematical process to get the best up to date measurement even when the whole data set is contaminated with random errors. But there is no free lunch in mathematics, nothing beats accurate measurements, no amount of math and statistics will make it better, even when it appears like that. In the moment I am happy... lets see, if the other reviews have a point. besides, why do you want to measure something you already know? Sugar and refined carbohydrates spike your blood glucose... its common knowledge... don't eat junk food and you do not need a CGM, Everybody who wears a CGM or reads this post, has already done the most important thing, which is educating oneself about nutrition... everything else is superfluous. Important update 05/Jan/2026 I am on my 2nd sensor. They last only 14 days for whatever reason, most importantly I guess, the glue will not stick much longer than that, probably the skin will secrete oils which dissolve the glue??? The good news was, that removing the old sensor was easy and it left no mark on my skin other than a tiny hole where the sensor was inserted. Unfortunately, the second sensor is also about 20 points too low, relative to the test strip. Of course one could argue that the test strips read 20 points too high, which I seriously doubt. Consecutive testing with test strips (Contour Next EZ) show readings within 5 counts of each other using brand new test strips. Overnight I get readings of 55 with the CGM, which is utter nonsense, because I am a recovering type 2 diabetes patient... even a reading of 75 overnight is hard to believe. The only useful thing I have discovered is that overnight my BG drops significantly. Morning glucose measurements are virtually useless, because of the classic BG spike after waking up. As soon as you out of bed, the BG is already on the rise and it can go up 30 maybe even 40 points within minutes and you have no way of knowing on which part of the curve you are measuring. So again, I have a warm feeling that maybe I have conquered my insulin resistance, just add 20 points to whatever the CGM tells you and when this is under 80 during the night, you maybe ok... still avoid carbs for the rest of your life Review: Does what I needed it to do. - I needed something to monitor my glucose that didn't require turning my fingers into a pincushion. It needed to be reasonably accurate. Continuous monitoring from the Lingo patch seemed to be worth a shot. Up front. I am not a physician. I am not being treated for diabetes. In general I am in pretty good health. I found it a little awkward to plant under my left arm. But is it doable. I shaved the area to give the device the best shot of getting a good grip. It stayed in place for the two weeks (14 days) the app will communicate to the device. I have an iPhone. Follow the direction to get the iPhone and app talking Bluetooth. After the app is installed, you will need to hold the iPhone approx 3 inches from the Lingo patch. It takes several long seconds (think 30+) for app to find the patch and start pulling in readings. Based on supplied documentation from Lingo/Abbott, the device is powered by Bluetooth. I guess you could call it another device from the IoT world. Powered by the power of the Bluetooth intranet. If your iPhone is more than 12 feet away (or has obstructions) the Lingo patch "will get angry" and stop pulling in readings. The remedy to restart data transfers was to move the iPhone 3 inches from the Lingo patch (and get it charged up again)..... One time I needed to disable/enable Bluetooth on the iPhone. On day 10 of the patch I had an annual doctor visit. This was my chance to get an accuracy measure of Lingo to a standard blood panel glucose measure. The patch reading before the blood draw was 84 mg/dL. The lab came back with 82 mg/dL. I was able to learn "bits and pieces" how my eating habits (type of carbs and time of day) were effecting my blood glucose levels. The last couple of years my A1C measures have "creep above" 6.0. "Fasting" measured glucose blood levels were still below 100, but just barely. In my case I discovered eating a load of complex carbs didn't spike my glucose (above 190), and it dropped below 140 within 2 hours. But the the glucose never seems to drop back to the 80's/90's. Healthy carbs, maybe not happy carbs. This issue was worst if eaten late in the evening or in the early AM hours. This eating habit was changed. I also found that "sneaking" a small snack was "radioactive" when measured in 5 minutes interval by the Lingo patch. Another area to modify eating habits. Except for a triple black coffee and cocoa powder (unsweetened) in the morning, I don't usually eat anything until noon. Lingo report me in the 90's-100's (yea waking up in the morning will bump your glucose). Not were I thought (or wanted) to be. As an experiment I ate 1/2 cup of fresh fruit and two heaping teaspoons of honey with the coffee brew. Within 60 minutes the patch would report a spike of over 200 mg/dL, (Lingo accurate measures stop at 200). Within two hours I would be under 100. For the next 3-4 hours the patch reported me between 68 - 89). This is how I got my 9:30 doctor visit/labs (10:35 draw) down to a measure of 82 mg/dL. Unhappiness. The distance limitation and "restart" of the patch is best understood as, "The patch and your phone have become inseparable friends". Get use to it. The Lingo app is a somewhat expansive. All I really need was the .csv download. I am handy with Excel. Again, I got all the analysis I needed from Excel and the Lingo .csv file. I couldn't find a way to enter notes in the app and have them download with the Lingo .csv file. But this may have been me not wanting to be a "Lingo App Master". It would be nice if the Lingo app would alarm/announce it has lost contact with the patch. Kind of a basic "IT 101 App" thing. Again, maybe I didn't dig deep enough into the app. For my purposes the device is a 5 star. ## Features - DESIGNED FOR IPHONE 11 DEVICE OR LATER. US Only. - UNDERSTAND YOUR GLUCOSE HEALTH.

I purchased 4 of these thinking I would get a good idea of what my diet and exercise was doing to my blood sugar for 2 solid months. First one worked okay. I did test it against a finger-stick monitor (Registered Dietitian here,) and found that it reads low. The monitor I used is made by Freestyle, same company (Abbott) that makes Lingo. My finger-sticks were about 5-15mg/dl higher than the readings coming from the biosensor. I tested it several times during the two weeks, most were 15mg/dl higher. I knew at that point that it wasn’t super accurate, but I could still see that even a tiny bit of sugary creamer in my coffee sent my blood sugar up and then crashing after a few hours if I didn’t eat anything else with it. That info helped me to give up the coffee creamer since I always tend to crash after sugar. I tested different sweet stuff, mixed with and without fats and protein. I was excited to continue with the next sensor and was planning to just stick consistently with my healthy low carb diet and not test sweets since I know I crash every time. I wore the first one without issue, knowing that it wasn’t super accurate I just looked for trends. It was fairly easy to take off after two weeks of wear, but I was surprised how sticky it still was. Hardly felt it on me or when I applied it or removed it. I could not sleep on my left arm or I would get odd swings in readings at night. After removal I waited two days and installed the 2nd. The second gave me a kinda high reading for me after an hour even though I hadn’t eaten anything yet, I think it was around 89mg/dl. Then I got the dreaded error: “Please wait 8 hours to see your reading or contact support.” No readings or history were showing. EIGHT hours? That seemed crazy. I did wait about 3, but nothing changed, so I emailed Abbott. I did get a response fairly quickly, maybe 12-18 hours. I’m sure a call would be quicker. I had to answer a billion questions and finally got an email back that a replacement was on its way. So I was told I could remove the sensor that I had on and trash it. Sensor 2 removal was tough. Since it was freshly placed, it was super sticky. After I finally got it off I was bleeding quite a bit, took a while to stop and yeah, that was fun. That one left a scary purple bruise. Since I still had 2 more sensors on hand I decided to place another on my right arm today (3 days later,) since my left arm is still bruised. I was a bit scared after the drama removal of the last one. Again, no pain applying. Whew. I was sure this would work. After one hour, (it takes an hour to calibrate,) this time it said my blood sugar was below 55. (Which BTW, I got that a lot when I wore the first sensor. When it’s below 55mg/dl, you don’t get a number, just <55.) then about another hour later I got the same error message again asking me to leave it on for 8 hours or contact customer service. Ugh. I did email Abbott a few hours ago and requested a refund for 3 sensors this time, no answer yet. I wore this one about 4 hours. Nothing. I just removed this second “error” biosensor and it was tough to remove like the last. New and very sticky, which is excellent if it’s going to stay on for 2 weeks, not 2 hours. Thankfully, I didn’t bleed much and no bruise so far. The app is pretty limited. Really needs improving. I did read that the Lingo goal is very confusing for a lot of people and I can see why it would be. It’s not intuitive. I got the hang of the app and was happy that it connects to Apple health and automatically adds my exercise. Easy enough to add food, but doesn’t connect to the Cronometer food tracking app that I use and love. I wish that the readings below 55 would be displayed since I tend to be hypoglycemic (low blood sugar) and it would be helpful to see what the lows were. I will say that I can typically feel my lows and my <55 readings did not feel like I was having a low. Wish I had confirmed a few of those with a finger stick. Great idea for self-help people like me. Needs lots of improvement. If you’re prediabetic or know an endocrinologist, or even talk to your family doctor about why you want to try one, especially if you’re worried about your health or have a family history of diabetes. I would ask for a prescription version of a CGM. Your doctor might give you one to try, but those need to be placed and removed by a health care professional. Your doctor will be more willing to give you a finger stick monitor if you’re willing to stick your finger first thing in the morning for a fasting reading, after meals and exercise. Monitor is cheap, test strips are pricy OTC. You can also get a prescription for test strips if your doctor sees a need. Seems scary, but it’s not too bad and it’s definitely more accurate if you're really worried about your health. ## Frequently Bought Together - Lingo Continuous Glucose Monitor (CGM) & App. Made by Abbott.
