3.2 is a complete downgrade

UPDATE 2: 4 months later, I have completely stopped using this app because of the 3.2 update. The only time I use it is to connect my sensor. Otherwise. Zukka does more, and does it better, than Stelo’s app. I remain incredibly disappointed in this app.

UPDATE 1: after receiving a generic, canned response from the developer that does nothing to address a genuine accessibility problem, I am downgrading my rating from 2 stars to 1. You know what they say: If I could give less, I would. I’ll use the Zukka app from now on.

Original review: 3.2 is hard to see, difficult to use, difficult to scroll, and I don’t want AI. The previous version (the lighter theme version) was much easier to navigate and see! This version doesn’t have the same TIR features and I no longer can find my 30 day time in range at a glance, if it’s even there.

Overall Happy But…

Overall I’m fine with the new app. I do like that they started showing the full range, not just >250. I do have a fairly major gripe though that they no longer show your average for the last 30 days. They are trying to make it better by adding 1M, 6M, 1Y. The problem is that it’s calendar based. So if you’re looking at the last 1 month data October 2nd, you only get 2 days of data. When we have checkups it’s usually every 3 months. So honestly having the # of days works better (7,30,60,90). Or even if 1month functionally translated to approximation of 30 days. As it is now after month end I lose all visibility for the last 4 weeks without looking at 6 months and trying to manually extrapolate.

New update

The new update on the black background is trash. It’s hard to see and hard to pull the info you are looking for out. Also won’t go below 3 hours and the tiny dots are hard to see. The old app showed averages right after the readings and calculated no matter how many days data it had. The trends tab that replaced it does not pull info even after two weeks of data. The events tab isn’t working at all, no matter how many times I input something. The old version allowed you to put notes on spikes…nothing of the sort here. All I’m able to see at a glance is current reading, no trends from the past week, month, etc. if you are trying to track glucose over time to, say, compute your approximate A1C it is now useless. The app and App Store response is to file an issue report but the issue reports are only for monitor issues. The AI function is also trash and I do not need it! Change it back!

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.
