Don’t subscribe! It’s a trap

My Dr was helping me setup my glucose monitor and he had me download this app, when going through setup I had to subscribe before I could complete, I did so and my Dr said that wasn’t the right one. I canceled and requested a refund but it won’t let me get my money back despite never using it once.

Offer monthly options

I like the app but I think that you should have an option to pay monthly $3.33 instead of
$29.99 annually or $39.99 is too high for some people

Awesome app

I have used this Glucose / Blood Sugar Tracker for years. It works great because I can send the reports directly to my doctors and they love it also.
No more paper and pen hand written reports.

I want my money back or at least a prorated subscription. Complete radio silence from the devs

Update #4 it is now September 2026 and I have still not had a response from anyone. I haven’t found another app out there that is decent that I like and I really and want to have this one back.
Have you fixed it to be compatible with Apple health?
Have you fixed it where I can manually enter my numbers daily without having to sync it with Bluetooth?
Hello? Is this thing on? Does anyone actually read these?
I paid for a year on this app and never got a full years use out of it. And now it seems I can’t even test it out without you wanting another payment. Absolutely sucks.
Update 3: anyone out there? Hello?
Did you fix this app? I had the paid subscription, but it ended up not working after iOS 26
Still waiting to hear from someone. Anyone. Ended up with months I couldn’t use after paying.

Update 2: still haven’t heard from anyone. It’s like the developer has abandoned this app.

Update: still have not heard anything from anyone about a fix or an ETA for the app. Have since several support tickets. I still have almost 5 months left on my subscription, would be nice to have a prorated refund at least. Yes I will not be using any more apps or paying for anything else from your company. I really like this tracker. It was the best one I’ve found so far. I paid the yearly subscription fee so I could have the A1c estimator (which is way off by the way).
Originally gave a five star review but walking that back now. iOS update has caused the program to stop working completely.
Someone on the web suggested uninstalling and reinstalling. So I backed up my data at Apple health uninstalled, then reinstalled the program. It worked one time and then crashed again. It also will not retrieve my backup data from Apple health. As of today when I try to use the app, it just loads to the blue screen and hangs and does nothing else.
Have reached out to support a couple times now and it’s been complete radio silence so today I will uninstall and go look for something else.
I know my subscription is only $30, but $30 is a lot when you don’t have insurance and you’re paying for insulin out-of-pocket.
