Lingo Continuous Glucose Monitor (CGM) & App. Made by Abbott. Know the impact of what you eat. 1 Lingo biosensor lasts up to 14 Days*. Designed for iPhone 11 device or Later. US Only.

The first time I purchased Lingo, I experienced an issue. I brushed up against the side of the car and the thing came unattached. It had only been on for 36 hrs. I was so frustrated, I contacted Lingo customer service directly and they were MORE than sympathetic and helpful. Everyone who is saying they won’t get their $ back, that may be true but contact directly and they will send out a new sensor. I LOVE this thing. It does not hurt to put on (I was nervous about that ) but not the absolute MOST IMPORTANT thing is to purchase the round bandages that cover the sensor(available on Amazon). I have worn one for 2 weeks , and now on my 2nd and the bandage protection (though not cute) prevents it getting inadvertently knocked off. As far as functionality, I don’t know if my #s are completely accurate, but that’s not what I truly care about. It has been most helpful in showing me how my levels respond to what I eat. It has made me so much more aware of combining proteins, fats and carbs together in order to prevent a spike. It most definitely jumps up if I eat sugar or pasta. I’d say the only slightly difficult thing to understand is how the lingo points are calculated in relation to the spike. From watching it , I think it’s the jump and the length of recovery time it takes the value to come back down. I wish I used a device like this long ago. Again , the accuracy isn’t 100% important as long is it’s semi consistent and not completely out of normal which mine has not been. It’s not for diabetics - it’s for people who just want to see how their body reacts to the foods they eat in order to make modifications for a healthier lifestyle. It has done that for me to the point where I feel like I want to wear one always! I won’t , bc it’s unrealistic ,but it’s become a daily challenge to stay in check. The directions are so easy but it’s helpful if you have someone else apply if for you. When I removed my first one after 2 weeks, it did leave a little ring(no bruising) but I’m sensitive to adhesive and it was more of a ring where the adhesive was. At the end of the 2 weeks, your data shows you when you had the most spikes and what you were eating around that time that caused the jump. Logging in that information through the day is really simple and you don’t have to be that detailed bc only you need to know what you were referring to like “broccoli and some bites of pasta” or “stressful situation about the car” Another little glitch is when you log that info, you need to adjust the time those things occurred. It gives you the clock but you need to make sure the time is correct when you go back to log. It’s very helpful to log so you’re able to see how those foods or events relate to the spikes. Anyway, I keep coming back and have been watching the reviews from the time there were less than 20. I felt compelled to write one (which I never do) bc I feel like people aren’t giving it enough credit for the value it offers!

First, let me say that I participated in a medical trial for 6 months in 2024 wearing a device similar to this, but it was a bit more sophisticated and from another manufacturer. Wearing it, and seeing the glucose readings it provided after consuming different food choices, and choosing to exercise, or not exercise, shortly after a meal was astounding. It changed my life. I was prediabetic and overweight when I began. After 6 months and striving to eat higher protein and lower carb/sugar, I had lost 30 pounds. I either rode my stationary bike or took a walk after dinner each night and those habits were all I needed to get myself on track. Again: WEARING ONE OF THESE HAS BEEN LIFE CHANGING FOR ME, so I'm sold on the concept overall. Fast forward to now--it's been 10 months since I've been 'on my own' and I'm recovering from an unrelated surgery and haven't been able to exercise the way I'd like for about 4 months. I still eat primarily high protein, low carb/sugar though--that hasn't changed. I wanted to try one of these OTC cheaper devices just to see where things stand with my body. I decided to try this one and applied it after my shower on a Sunday night. It lasted until Friday afternoon, after a day at the pool and wearing sunscreen, even though I tried to avoid getting sunscreen near it. I already know from wearing the ones last year, that they stay on longer (usually 7-10 days) if you cover them with a nice sized waterproof bandage. The one I wore last year had a little patch that could cover it but it wasn't enough in my opinion, so I still used the bandage too. These don't come with any kind of a cover, fyi. You'll want to avoid hot baths/showers, body lotion, etc. to help it stay on your skin for the duration if possible. A little disappointed that it didn't make it a full week, but I got enough insight over 5 days or to still make it worth it for me.Some other notes after wearing this the past week:*The app is perfectly fine, and I had no issues using it. You have to leave it 'open' on your phone to get updated readings. It takes an hour to calibrate after you connect it to the sensor, via blue tooth. The readings seem fairly accurate as far as I could tell, and were in line with what I saw wearing the more sophisticated device last year. It's enough information to see what foods do to your sugar levels, and you can see in real time the effects of exercising after a meal as well. The app gives you information, targets/goals, and prompts you a bit to examine your habits in relation to the readings you receive. A bit of 'coaching' is there if you're interested. You can log your food and exercise if you wish to correlate those with the glucose readings, but I was less interested in that since I already understand how those choices affect the results.*It's super easy to apply--just a tiny sting (more like a little pinch) and it's in. You'll need to swab the back of your upper arm with an alcohol pad or cotton ball/alcohol before you apply it to clean, dry skin. Once you apply it to your skin, you scan it with your phone to pair the sensor with the app.*It's small and unnoticeable for the most part. Perfectly fine to wear sleeping, and covered by any shirt with a sleeve.*I can't compare this with the other OTC option as I haven't tried it, but I'd say for the price, this is a great option to get some honest feedback and motivation if you're looking to make some progress for taking better care of yourself and making better food and exercise choices. One thing I will say is that starting out with this type of device last year, it took me a few months to really start to see changes in my readings/numbers, and health. I had elevated blood sugar from years of eating poorly, and that doesn't change just because you eat well and exercise for a week. It takes time for real change, but it definitely worth it!

This is not bad but it’s not great either. The cgm is a big confusing to install but easy once you figure it out. It seems to have the same margin or error as the Stelo so not that different there. The problems come with the app itself, horrible. They use some weird made up system called lingo points that is not explained at all. It seems like it might be a mini game that you try to keep your points above or below a certain imaginary number but since nothing ever tells you of you should be higher or lower or how to raise/lower points it is useless. Also there are challenges that are locked and unusable so not much help. Over all app gets 1/10 for actually showing your blood sugar but useless in all other ways. You can’t even connect other apps to it like the Stelo can. The cgm I give it about a 7/10 because it seems to be staying on and is about as good as the Stelo (that’s not saying much) with numbers 10-30 below your actual numbers. Will not be getting another one
