Hellolingo UK Avis 

I was promised a pain-free device. Unfortunately I couldn't try since the needle was longer and wider than anything you could ever imagine. Suggestion? Make the needle smaller and thinner. This would have passed side to side in my arm.

I used this for 8 days as part of a free trial in return for an honest review.
The product does exactly what it says, but I’m not sure how beneficial it would be for anyone who doesn’t need to watch their glucose levels.
The positives were that it was very easy to apply, worked well and monitoring on the app was also extremely easy.
The practical downside was that I didn’t enjoy wearing a biosensor. Even though you can’t really feel it, I knocked it a few times and was aware of it.
I didn’t really feel that the data it gave me was anything groundbreaking. There were some useful tips from the app which I enjoyed and it was interesting to see my glucose levels and that I don’t have any red flags with them, but I felt that this product is really only useful for those who have a medical issue.
I didn’t use it to its full capacity though by entering food I’d eaten etc. So that might be something to consider.
Overall, a useful tool and a good, self explanatory app, but not for me.

Great insights. Loved using this product. Reinforced what I thought would happen when eating certain foods, but helped me make choices that would incur less of a spike. I found the app to be a bit slow when updating my data. Often, I would have to close the app and reopen for it to show.

I have been looking for an opportunity to try one of the glucose monitors thanks to Home Tester Club. Lingo Glucose Biosensor has been great so far. I love the fact that it is very sensitive which has made very aware of every single food item that I have consumed since started using it. I didn’t know that how certain food items in my diet were actually high in sugar and how they impacted my health.

The applicator is like a magic and in split second, it is in; absolutely no pain at all! I am not sure how this is even possible, well I am super impressed.

Moreover, recording my food intake is super easy and I can go back to check how my diet has been. It also creates an input notification which indicates that there has been a spike in my glucose level.

The only thing that should be improved is the sticky tape. The sticky tape is stuck on my skin however the biosensor has come off slightly and it is not fully attached to the sticky tape,although it has not caught anything. It still functions as it should. Overall, I am very impressed!

It’s a great device which has helped to log and monitor the blood glucose levels however it has poor retention.
I have had to use a surgical tape to hold it in place, as the original seal kept coming off the skin.

I've never had any issue with glucose levels before (to my knowledge) but thought I best check my levels anyway. The sensor was always updating with my phone so painted a very good picture of how good/bad I was doing.

The app is easy to use and the device was easy and pain free to apply to my skin.

I wish that the app would integrate with Apple Health on iPhone as that is where a lot of my other health data lives, so would like everything centralised.

Other than that I wasn't really sure what I should be doing with the app, as I have said it was useful to see the peaks and the troughs but as for what it all meant, I still don't really know now.

I am NOT diabetic however being a 40+ lady who is more conscious of diet health and weight this was fantastic easy way to check via a user friendly app
The device is simple to use on your arm and stays for 14 days it is painless to attach and never came off
The app downloaded on my phone easierly great addition to add challenges put on you meals and snacks and check what your blood sugar levels are for you when you spike or dip

I found the monitor easy to install and easy to use. Informative, interesting and a great app to view the data.

Came with easy to use instructions. Once downloaded the app it was quick and simple to set up and use. The sensor was painless to attach to the arm. Great that its even water proof. The app was easy to use and gave constant reading of glucose levels. The app shows you when you are having a spike or dip and gives the option to record if this was for any specific reason ie food or activity. You are able to use the app to set daily or weekly challenges like drinking a certain amount of water per day, which at the end of each day it would ask you if you had managed to complete it. If you were having a dip or spike the app would also offer suggestions like doing a few calf raises exercises. The app and bio sensor were very easy to use and I think if you are looking for an addition to your health journey this could be useful for anyone looking to change eating habits to suit their own body needs.

I had quite the arduous time in applying the sensor - took x3 sensors to have success. That said, Lingo were very fast in shipping replacement sensors out. Once applied, and app downloaded. An hours wait for the sensor to connect and work its science commences. I have to say I didn't notice it was there for the full x8 days and was reassured that my glucose levels are within the 'normal' range. I would absolutely recommend this to anyone wanting to, or have been advised to check their glucose levels. The app is very simple to use and understand. Very user friendly design. Only reason I have given a '3 star' review is for the application of the sensor - definitely a challenge and if not successful, there is no 2nd try - for another sensor needs to be shipped and replaced. Fix the applicator issue and would be a '5 star' rating every time.

tried the Lingo Glucose Biosensor for a couple of weeks and was impressed by how much insight it gave me into my diet and exercise habits. The app is super user-friendly and shows real-time glucose trends, which helped me understand how certain foods affect my energy levels. Applying the sensor was easy, and it stayed on for the full 14 days without issues.

Very easy to apply and fairly pain free. The real time visibility of my glucose levels was great to monitor the impact of what I was eating and when I was exercising. The app was easy to navigate and the notifications helped me manage spikes better

Really easy insights
Loved this. 100% painless to apply.
App really easy.
Didn’t have a single glitch.
Learned so much about my health.
Highly recommend!

Painless to apply, like a mild nettle sting for about 30-40 seconds. Within an hour or so of wearing, was providing me with some great data. Helps identify foods/behaviours that cause spikes in glucose, helps you flatten out the spikes over the course of the day to stop energy slumps/brain fog. Is it a permanent device I would wear like my apple watch? Not so sure, great short term educator however. Wore device for 2 weeks which is lifespan of sensor. Sleeping is a little bit of a pain, sometimes catch it during the night which isn't ideal.

I’ve worn the sensor for two weeks now and I can’t tell you how interesting the information has been! It’s really easy to unpack and apply, I thought there might be a little pain when I saw the spike on the sensor that goes into the underside of my arm. Not at all it was painless and quick and stayed on for the whole two weeks, even in the shower, I thought it might come off but it didn’t. There was no inconvenience with wearing it. I didn’t knock it or pull it off which again I thought I might. Over the two-week period I could see immediately the impact of any food I asked or more importantly any drink I took into me.
It was amazing when I drank a can of Coke. My glucose went off the scale but also reassuring to know that most of my diet was within range all the time. Even overnight, I could see the impact of not eating and drinking I would certainly recommend this product to anyone who is interested in monitoring their glucose levels and getting an indication of how the impact of how diet affects you!

After 10 days with the Lingo Glucose Biosensor, I’m seriously impressed. It gives real-time glucose insights that are easy to understand and act on. The app is clean, intuitive, and turns raw data into meaningful feedback. I’ve already adjusted my meals and workouts based on trends I wouldn’t have noticed otherwise. The sensor is light, comfortable, and barely noticeable — no issues with wear or connectivity. What really sets it apart is how empowering it feels. You’re not just tracking numbers; you’re learning how your body works and how to support it better. In just over a week, I’ve seen better energy, fewer crashes, and smarter food choices. Whether you’re into fitness, performance, or just personal health optimization, Lingo makes it effortless and motivating. This is wearable tech done right.

The set-up instructions were a little unclear, but the video was more helpful. Once attached the sensor remained in place. The app set-up process was simple and overall the iPhone app is easy to navigate. However, the readings after a few days seemed almost random and were highly unusual so unsure if this could be a long term reliable monitoring method.

Nice to check my glucose, easy to apply to the skin, easy to use app, really impressive, will definitely use it again, i do recommend to anyone who wants to check glucose levels

I track my excercise and calories regularly so I was keen to try the biosensor to further understand the impact of both on my body.
I was curious about blood sugar levels and it was very reassuring to see in realtime when my levels were within healthy range, and also to see how my body was reacting to food, exercise, sleep and stress. I found the information in the app to be informative, but I’m not sure, having used the sensor for a 10 day period whether I would feel the need to use it again.
The product was very easy to set up, and I liked that my excercise activities were directly imported from the fitness app on my iPhone. applying the sensor was more painful than I had expected, and my arm was sore for the first 36 hours. I also found that my phone battery was massively impacted during use.

The device was really easy to put on, although I wish I had thought more about the placement and I went for my non dominant arm, assuming less used and out of the way but forgetting that I sleep on that side. The data came through quickly and it was great to see I was within normal ranges, very reassuring. Unfortunately by day 7 it was getting too uncomfortable to wear so I had to take it off, my arm felt bruised for about a day but then fine. I found the data useful in helping me to keep hunger at bay and to see how food, lack of regular food and sleep affected my scores, overall a very interesting trial with a device that worked quickly and easily with an app that was as simple as touching the device with my phone to set up! Would recommend to anyone interested in knowing more about their health.
