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

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.

Used to work nicely with Dario; doesn’t anymore. Canceling…

Canceling sub; used to work nicely with Dario; no longer connects at all!

Does not work

Cannot use, instantly crashes when I try to use app, I paid 40 dollars for a worthless app. I hope I can get a refund from apple. Do not recommend.

Horrible App

The app doesn’t even stay open long enough for you to do anything!

Update: OMG they fixed it!

Update: They added sliders in the settings to turn off the additional "features" and now I have a useful app again. The rest of my subscription will be used with gratitude! I will be happy to renew at the original price if they don't attempt this monstrous behavior again!
Old: The latest update destroyed the functionality of the app IMO. I paid for a subscription and have been using it for a year without issue and now I have to close and swipe away "share the app!" And "upgrade" advertising, I have to scroll past a "daily carb budget" widget to access the part I actually use and there's no way to remove it and now they want to double the subscription??? It used to provide a simple way to track meds, blood sugar, weight, insulin, etc and now it is cluttered and obstructed and vibes like a pushy car salesman. Unsubscribing and uninstalling 😡👎

Version 3.16.2

No longer works on my iPhone???

Great App Now Unusable

This has been an excellent app I highly recommended, but is has become unusable. In May 2026 it started freezing and shutting down. Then at the end if May an update made this happen less often. Now it is back to the same issue. I communicated and developers just said the update should fix things. Well, it did not. And it does not matter if I am connected to Apple Health or not☹️

Does not work on my iPhone

Paid for a premium subscription. Can’t even open the app for a moment before it crashes. A waste of money.

Great App but can’t use the Carb area

Love this app but please show how the carb area works. Changing the budget is easy can’t seem to log any current grams
Thanks

Failing Formerly Very Good App

I have used this app for four years and found it very useful. I appreciated all the improvements made since then. I almost quit using it as the performance deteriorated the past few months. A few weeks ago, the new update made great improvements, and I was very hopeful. However, this past week it started crashing and having issues. Now it is unusable. I contacted the developers, but have yet to get a response. I will not be continuing to pay for this app unless there is dramatic improvement. I used to recommend this app all the time. Not anymore☹️

Scam

Does not work for freestyle libre 3
Plus even though this is what popped up when I searched for it.
Waste of 40 dollars.

Update killed it IMO

The latest update destroyed the functionality of the app IMO. I paid for a subscription and have been using it for a year without issue and now I have to close and swipe away "share the app!" And "upgrade" advertising, I have to scroll past a "daily carb budget" widget to access the part I actually use and there's no way to remove it and now they want to double the subscription???

Used to be a good app. Now constant upselling!

This used to be a good app but now every other day it tries to upsell you for multiple additional expensive services. If you want to be interrupted constantly by ads, get this app. Once a week ads is OK but every day or every other day is too much. The place to go for harassing ads is Facebook but I don’t need harassment when trying to care for my diabetes.

Excellent, attentive developers.

Does everything I need it to do, and even more. And when a problem came up, the company paid attention and fixed it quickly. That kind of service is hard to find anymore.

No longer opens

Just made me do an update and now I cannot use it at all..

Not working with IOS update

Update: 5/14/26, prompt response in fixing the problems and added a couple nice features to the app, AI to track your carb intake by taking a photo and Bluetooth for CGM. I have tried the AI to track carbs and it is close, but not perfect. Haven’t tried the CGM yet. Keep up the good work I have used this app for a couple of years and enjoy the tracking.

Update 5/9/26: new rev 3.15.0 is broke, it is looking for a non existent glucose monitor so the app does not function. Please have it manual connect instead of when the app opens Updated phone to 26.1 and now the app does not open. Opening screen pops up and a few seconds later shuts down. Unable to input any data. I really liked this app for tracking blood sugar but may have to look for a different one.

Improved since update

Originally this app would not function as it tried to sync with Apple health. This appears to have been improved. The app is now functioning since the update.

Glucose app & Apple Health conflict?

I recently gave a one star review on this app. Yesterday I received an eMail (probably from a bot) suggesting I update the app and consider a new review. I previously had removed the app when it no longer worked, reinstalled and still had conflicts. The app absolutely wanted me to enter a glucose monitor that was not on their list and I was unable to do anything else with the app. This morning I again removed the app, but this time I turned my phone off for about 5 minutes. When I restarted my iPhone I went to the App Store and re downloaded the app. When I opened the app it again went straight to Add a Glucose Monitor, but this time, after about a minute, that screen went off and the app seems to be functioning normal again. All of my previous information had been saved by Apple Health and automatically was synced to this app, so I didn’t have to re inter any data which I’m grateful for. Time will tell if this apps continues to work.

New features are annoying

After this last update it’s trying to push Bluetooth monitor connection and upscaling their subscription that would cost me more than my yearly membership. This is getting out of hand. It was fine before and now just getting worse

Fixed and offered 50% off upon renewal. 😊

App stopped working
