Hellolingo UK Avis 

This item is great, I managed to see where my glucose levels spiked and with the extra challenges you are able to make small changes to a healthier lifestyle.
If you are worried about your glucose levels or are pre-diabetic then this is what you need. The app is easy to navigate and you also are able to monitor daily and hourly levels.
Would 100% recommend this.

I was really pleased to have the chance to try the Lingo Glucose Biosensor. Applying the sensor was quick and easy, and setting up the app on my phone was just as simple. The app itself was excellent — full of helpful information, clear insights, and practical tips to support the goals I set for myself. It gave me a real understanding of how my food and lifestyle choices affected my glucose levels in real time.

Unfortunately, I did accidentally knock the sensor off after 6 days, and it couldn’t be reapplied, which was disappointing. Something to be mindful of!

Overall, I found Lingo to be a really useful and easy-to-use tool for increasing awareness and supporting healthy habits.

The app and device were good for you to check your glucose levels throughout certain times of the day. Gives you insights of what your levels are doing depending on the tasks you do and food you eat. The tips in the app on food intake and exercise are good to help understand what you need to do to keep within normal range

When the product arrives, the instructions are made clean on how to apply the Biosensor, however it would benefit from providing an alcohol wipe to help clean the application area.
once applied you barely notice it, only now and then when taking clothes off or showering you may knock it.
Having not used a Glucose monitor before it was interesting to see the Glucose levels and get an idea of what caused it to spike and what didn't.
overall, for anyone that is into fitness and wellbeing and wanting to take the nutrition to the next level I would recommend this product.

The Lingo Glucose Biosensor came well packaged with clear instructions on how to use and apply to the arm. The application was simple and not painful at all. Data would be transferred via Bluetooth direct to your phone and at any time you could check on your glucose levels. A great gadget for anyone with Diabetes or just wanted to be within a healthy glucose range.

I was excited to try a CGM to understand the impact certain foods had on my blood sugar and to support my diet.

Please note: I was provided this device for free for an honest review.

Unfortunately I was left a little disappointed by this product.

1) There is so much plastic packaging for such a small sensor, which makes me feel uneasy as it just feels unnecessary.
2) No alcohol wipes were included to clean the surface before application, for such a premium priced product you’d expect something so small would be included.
3) The adhesive is terrible, my monitor started peeling away after 2 days which then started to cause pain in my arm.

Overall this device should not be marketed at the price it is, it’s ridiculously expensive for such a poor quality product.

I unfortunately wouldn’t be able to recommend this product to anyone nor would I purchase again.

Good product….but
Product arrived and I was surprised by the ease of application and linking of the app. It’s pretty much painless and extremely quick. Even for a person who is not normally keen on needles o would really praise this product for that reason.
Once I started with the test the information I got was interesting but nothing more, maybe the lingo point element could be better explained, but I concentrated more on the impact of food, stress and exercise on my glucose rating, all pretty informative and in some cases surprising, it actually made me check a couple of food items to check the ingredients after a particularly large change. I would say that it does involve being proactive and checking the phone app pretty regularly which can be irritating, an upgrade to a watch app may be a good idea.
I removed my sensor slightly early as the position I had it was catching on clothing, this was a minor issue and could be improved with experience. Would recommend to someone who needs this type of item

The app may be clunky but the data is incredible! A game changer - seeing the impact of processed food and many carbs! If you've not done it or are thinking about it - GET ONE! It's a life changer!

Sensor is small and comfortable compared to others.
App interface is ok - nothing special but not bad.
Connectivity is hit and miss. Went for at least 13 hours unconnected more than once which seems a CGM device useless as you want regular information.
Worst issue is that it told me my sensor had expired and I removed it, only to discover a week later that I had done so a week early after the app reminded me to buy another - really unhappy about this as I missed out on a week I paid for.

Mixed feelings.
On one hand its a good device to learn how your body responds to the foods you eat and how making dietary changes help to steady your glucose.
Its easy to apply and the app is easy to navigate. It also comes is a pretty box (not that its much relevant to how it works).
On the other hand there are few issues with it:
1. The sensor comes off easily. It would be good if in the pack there were several over-patches included. My 2nd sensor almost came off entirely only few days after applying it. I patched it with a dressing. However I cant be sure if the data was correct as the sensor almost fully lifted itself at one point.
2. You can not transfer the graph/data and can only access it via app/online account.
3. The food choices list is marketed towards US market. There is lack of certain foods that are typical for Europe and it would be handy to have food free type option.
4. When scrolling via the graph on the main page it often sends you back to its current position. It’s rather annoying when you want to see you progress on the main page.
The idea behind it is great. However given the price it would be good to see few improvements, especially on the adhesion side and data transfer.

I have been using Hellolingo since November and through using it I discovered that my blood glucose levels were higher than I had expected to the extent that I was borderline pre-diabetic/diabetic confirmed by an HbA1C which shows glucose effect on haemoglobin in red blood cells for the previous 3 months. Since then I have been keeping to a very low carbohydrate/ therapeutic keto diet and my weekly average readings are coming down and this is allowing me to use body fat for energy and lose weight. So very very worthwhile.

I have found this useful to monitor blood glucose but share some of the thoughts other reviewers have on accuracy and sensitivity in terms of needing to be close to device etc. However, there will be a physiological delay in glucose levels after eating as food is processed. It just monitors glucose - does what it says on the box! For non - diabetic people , I think it’s fine. For diabetic people there is the free style Libre if eligible.
The tips and tricks on app have been an interesting read and echo ‘ The Glucose Goddess’ regime.
Few suprises for me regarding foods that cause me to spike - sadly lentils and pulses but experimenting with how, when I eat these and what quantity means I can still eat them. Obvious ones - carbs, starch and sugars but again the tips and tricks suggested means after meal based on protein and veggies, now and then a small pudding or treat with a little walk after keeps the glucose steady.
I did 2 week trial and now will use for 3 months to figure out an eating plan. I do not have anything to compare it to but did have trial of free style and find this easier as not having to swipe phone near device for reading as Bluetoothed although the former may no do this.

No earth shattering insights.

It is interesting to see how you react to what you eat, but, in general, it is quite simple: eat non processed foods, avoid sugar and other carbs, especially simple carbs. You learn this within the first week.

The app has to be on all the time so it does drain the battery of the phone very quickly.

Would I buy it again? NO

I must say that these CGMs are not without their glitches ranging from, not working at all to an unacceptable level of inaccuracy , but , and this is a big but ! When they do work well they are superb and provide great insight into dietary habits the the shocking effect of fast food and excessive carbohydrates. This is priceless information so I hope the glitches are resolved.
The other reason for five stars is that their customer service is absolutely excellent. I cannot speak too highly of their response and level of customer consideration.
I for one am sticking with them in the hope that their technical team are resolving the issues and one day they will be close to 100% perfect.

There is just too much to gain in having an off the shelf continuous glucose monitor that works.

PS, having fitted and removed many of these I do think that the tiny needle is just too flimsy for the job, I am no expert on CGMs but I am an engineer. Just thought I would mention this.

Once device arrived I was asked to register and pay £1.00. All three of my cards have been declined. I've been wearing the sensor all day, only to read that the app is only available for iPhones, not Android yet.
I've bought for nothing, it seems

Please avoid buying this product it shows highly inaccurate readings. It shows 5.9 mmol glucose at Lingo app and when I did a blood test to compare it was actually 10.5 mmol. There is a huge difference. I understand this is not a medical device, but if it shows half of what your current readings are what is the point carrying that on your arm for 14 days. I am glad I had the shortest subscription. Total scam.

UPDATE: Customer service was very helpful, they have sent me another device next day, it still shows a discrepancy though still have MIN 1 to 2 mmol difference. Device shows that I have very low blood sugar but in fact my blood sugar levels are fine. Currently device tells me I have less than 3.1mmol, it no longer can provide the exact number, which is not true. I have spoken with customer services today again, and now the supervisor will decide my refund process since product is not fit for purpose and I rejected the 3rd device.

Frustrating. I haven’t even got to the end of the first week, and I’ve caught the sensor on a strap and that was enough to dislodge and removed the sensor. The “proper” sensors come with covers (like plasters to go over the sensor) and these don’t so I’ve just wasted my money here. I should have had 14 days of readings and I’ve had 4. If only they’d include those covers.

Not for type 2 diabetics, although they don’t actually tell you that when you’re buying.

Max level recorded is 11.1, which is pointless and frustrating as the same company does Libra Freestyle which goes up to 21.

No option to set yourself as Type 2 diabetic so the ‘healthy range’ doesn’t adjust for you (healthy range is higher for us). Therefore you spend much of the time outside of healthy range.

Lingo point system is utterly ridiculous and doesn’t actually mean anything. You’ve ‘failed’ before you even wake up.

Not only a complete waste of money but quite depressing!

I was really delighted with Lingo when I first got it, but when used over a long period, I find it pretty clunky. I have had two sensors stop working (one was replaced: the other was within a couple of days of its end so I didn't bother). And the app is very slow. Most of the time when I open the app it will say "updating your glucose data" and takes a few minutes. Sometimes it just freezes. I'm going to try another CGM now and see if I can do better...

The device itself is the same as other companies but what sets Lingo apart is its customer service.
