Only ‘below 70’ readings, but not WHAT the number is below 70
I’m not dependent on insulin, I’m not diabetic, but I have hypoglycemia and a CGM helps me monitor that. I was using the G7, but paying $100 every 10 days to use it. I saw I could get 3 months for nearly half that price, so I tried it. I loved the simplicity of the G7 app and the device so I am comparing my experience of that to this, the stelo. The low blood sugar sound warnings of the G7 saved me many mornings of waking up feeling “low hungover”, and the ability to read WHAT my glucose was, and being warned it was trending down to 55 so I could intervene before I felt poor, and when it dropped below 70 mattered. A 55 is much different that a 68 and that feature is lost here. That is WHY I got this device, because even though I read Stelo couldn’t pre alert or I. The moment sound alert me for a low (which, I don’t get why?) it would at least allow me to continue to track my numbers if I got really good at checking my phone every 15 minutes and try and help me beat a low. I’m unable to get insurance to cover cgms because I’m not diabetic, and was hoping this would be the answer to a three month long battle that ended in it won’t kill me to go low, so, oh well.
This (stelo) was supposed to be my lifeline, but feels somewhat useless. I still need to track my numbers so it somewhat does that, but if you’re like me and rely on seeing your actual low numbers and not just ‘low’ and have any other options besides this and a finger stick - don’t waste the money. The app is riddled with AI and the chart is hard to read. I was really really hopeful after such an amazing experience with the G7s but I am so disappointed.

Downgrading from 5 stars
I wrote a previous 5 star review because I find the app helpful and easy to use, but I’ve run across a couple of issues. 1. The sensors tend to give wonky readings, significantly too low or high, for the first 24-48 hours, and there’s no way to delete that bad data from the app, so the glucose averages for 1, 3, 6 months, etc., is completely useless. They need to remove that function if they aren’t going to let you delete the bad data. 2. Last night, while on vacation, I was randomly logged out of the app. Of course I don’t have the password with me, so I had to reset the password and go through the entire setup process again, then re-pair the sensor, so thank goodness I had the applicator with me! Otherwise I wouldn’t have had readings for the next week.

Fresh UI but no gain in functionality.
I will buck the trend and say that I actually like the dark and moody design. So props on the fresh UI. But, I will echo what others have said about some missing functionality.
What people want and expect (rightly or wrongly) is literally an OTC version of the G7. They want it to work and act like the G7 does, with all the same metrics and alarms. But, you didn’t want to make an OTC version of the G7. That would cannibalize your prescription sales for the G7.
You also needed a way to turn a profit on G7 SoCs that didn’t make the cut, thus the Stelo was born.
It’s such a simple answer that it’s counterintuitive. Make the Stelo the same as the G7 but remove the automatic bolus function with insulin pumps. It really does seem so simple, it actually hurts.
Barring that, you still forget to add Widget support on iOS. Background App Refresh for the Stelo app on iOS and watchOS, direct to Apple Watch support, and alarms for low and high blood glucose.
I love the dark mode theme, but people will wine about the cheese you moved until you give them a light theme as well. The sad thing is, if this app where coded using Xcode and/or Swift, then there would be native support for all of these things in the framework for the app.

Easy to see glucose trends
I’m on my third sensor now, and this one seems to be least accurate. The first two started reason high compared to a finger stick, got more accurate after a couple of days and the ended up reason low. This one was very erratic for the first day, jumping up and down every reading, then settled into being fairly consistent at about 25 points low. But it is still useful for trends. One request I have is for the ability to copy meals. I often will make a batch of lentil salad and eat it on several consecutive days, so I would like to copy the entire meal instead of having to select all the ingredients again.

Excellent with a few bugs
Type 2 diabetic, have used Stelo since June 2026. The sensor and app info have been life changing for me. I may go off medication as my glucose is now so well controlled based on what I’ve learned. Sensor usually has first day of high variability, then generally is accurate compared to finger stick. My first two sensors were off by 10-15 points, but that resolved when I figured out the best place to apply them on arm. The app basic info is terrific. It’s so useful to track specific meals and events and see their impact. I agree with other reviewers that it would be nice to have option of dark vs light screen, and I don’t like the loss of time resolution when viewing longer periods on the basic glucose plot in latest app. I actually like the AI comments. For meal entry there are a few bugs when ai selects a high sugar version of a food instead of the sugar-free version I listed, and other bugs. But persisting I can usually get a reasonable report. And it’s great to see daily nutrition info in the main page. Overall the product is terrific, with some bugs that I expect will be worked out over time.

Mostly Flawless
I have had almost no issues with the app or the sensors. I have had one bad sensor in the past year, which Dexcom replaced almost immediately.
There are some features I wish they would tweak a bit. First, the glucose graph. As I’ve never gone above 250 or below 70, a smaller scale on the graph would give me more granularity. 115 and 95 look pretty much the same on this graph. Also, the meal selection would benefit from memory settings. I eat the same lunch nearly every day, but I can’t save it and automatically add it.
Overall, I love the peace of mind this app gives me. And as long as I keep my phone close by, I have no issues with the sensors whatsoever!

Doesn’t load
Exciting that there’s a new app but unfortunate that it won’t open on my iPhone.
Redesign is user-unfriendly
Please, please help those of us who preferred original design to revert back to it. I truly can hardly read my range, am missing 1 hr overview, and am altogether struggling with new and not-improved visuals. Please! I was so grateful to have this monitor and the original app.
new updates kinda useless
so the new Insights are useless. you get notifications you have an insight when they are unchanged. and they always refer to “yesterday”
usually it is the day before yesterday. could it at least refer to the actual day or date? at least if it isn’t updated you’ll know.
STELO BOT IS USELESS. There is no conversation. just AI RESPONSES. This was a COMMENT ON THE NEW APP NOT AN ISSUE WITH AN ORDER. HOW ABOUT a REAL PERSON acknowledge the app issue?!

Good product-worst app ever
The sensor when you can pair it is good. The problem is the app. It’s the worst. Pairing could go smooth or a nightmare. Not sure why this hasn’t been resolved yet. Hate that oura only pairs with this.
If I could give zero stars I would!
This has been a very frustrating experience so far, and I have tried using these now for about six months! I am about to switch to a different brand because these have continual issues. The readings are wildly inaccurate compared to my fingerstick test, often showing readings around 99 went in real life, my blood glucose is showing by fingerstick test to be 156 or higher. The app constantly has issues, the hardware has issues, I frequently get messages saying there has been a temporary issue and to check back three hours later, and after three hours it has not rectified itself, so I do not get readings during those times. The adhesive often comes off before the length of time of the lifespan of the device, and very often it stops doing correct (or any readings) before the end period. I understand that it is going to be somewhat different than the fingerstick test and that there is a margin percentage of error, but these fall very far outside of those lines. The only thing that this is actually been helpful for, is showing me how much my glucose does or does not rise after certain things that I eat. But as far as keeping an accurate, safe count of what my glucose actually is, it does not work. I didn't even realize it was so far off until I had blood work done and it showed my A1c was still too high, in spite of my CGM app and monitor showing that it had been well within range 96% to 100% of each day for several months! So I started comparing it to a stick test, and discovered that the Stelo CGM is anywhere from 40 to 80 points lower than what the stick test actually shows! Do not rely on this for medical safety! And while I appreciate the company reaching out to me to tell me how to reach their customer service, that doesn't work either. You can't ever reach a human being, it only does their little robot, and then you get a message saying to fill out a form, which I have done numerous times, and then the solution is either that they closed the request out or they send you another sensor. No human being ever actually replies, and they just keep sending emails saying to fill out a form, but filling it out does not resolve the issue.

Good and bad
The monitor is very helpful even if it isn’t a perfectly accurate read because it is still helpful to monitor how you’re eating is impacting your blood sugar. However, I’m constantly experiencing connection issues with the app. And using the bot to problem solve has been extremely irritating and difficult. Reconsidering renewing my subscription due to this.

Annoying problems
Ever since the recent update, this app is very glitchy. I’m getting notifications about meals I had yesterday. I tsp the notification and it opens a blank page. I’ll enter a meal and it disappears. The spinner for the time is glitchy.
Not worth downloading
Wait for the next version.
Too dark
New design is too dark, hard to read. Also when logging in food info the AI gets it wrong. It would be nice if there were a favorites tab where you could easily enter a meal that you often eat without having to reenter the whole thing. Also again the darkness of it is very off putting and hard to see and the AI bot is negative in its comments without having all the information

Great and inexpensive solution
I used Stelo to monitor my glucose temporarily. Stelo provided peace of mind for us. We used it for a few months and then canceled after concluding that my glucose was fine. I would recommend their product and the app for its connectivity capabilities to the device.
New App is too Dark
I like some of the new functionalities of the new app. But it’s just too stinking dark. Is there a setting for LIGHT mode. If not please give us one.
Also customer service is not good. You can only communicate with a bot that seems to be lacking in artificial intelligence.
Follow up:
Been using the new app for several weeks now and still I Do Not like it. Funny enough I left Lingo and went back to Stelo because I liked the Stelo app better. Can’t say that anymore.

Only drawback is confusing activity tracking with wrong date’s steps in calendar yesterday and prev.

Doesn’t work
Please don’t buy it doesn’t sync. I am going to ask for refund
Doesn’t work
This won’t even connect to my Dexcom, so there’s definitely some updating that needs to be done for this to be a much more useful app
