Great but needs some improvement

I recently came across this app and instantly downloaded it for my wife, she used the app for a couple days and said she really liked it so we subscribed to the unlimited plan, meter came way before it said in the notice. One thing she could really use in the app is customizable setting to have the app do the insulin calculations for her. For example she checks her numbers it syncs to the app then she has to close the app and open the calculator and figure out the amount of insulin would be great if you could put in the math and the app do that for her. So she checks her numbers the app displays the reading then a notification or something goes to correct this take “2” units of insulin, or eat this 30g of carbs basically eliminate the need to close the app and use the calculator. That’s the only thing I could think of that could use the app other than that 10/10 great app and cheap too!!

The best app there is!!

I looked at several apps but none of them come close!
Complete tracking of everything. The logging feature for food is the best. Save your common meals, easily adjust portions, search the extensive database to add foods, even use the built in barcode scanner! Now use Siri Shortcuts to add meals. Connects to health app seamlessly, logs weight from iHealth Bluetooth scale or enter manually. Track a1c, carbs, calories, insulin intake, medications, even activity! This truly motivated me to take my type 2 diabetes seriously. From July to October I got my a1c from 8.0 to 6.4, my weight from 305 to 278. Medications did most of it but understanding portions and the easy logging made a tremendous difference.
I can’t thank the developers enough! My only wish would be to have the one drop meter and strips covered and paid by my Medicare insurance. Still, the free to use app is far and away the best I have seen.

Great app but logging food via Siri does not work

One Drop is a very nice app! Overall it’s clean, Informative, and simple. The AI is a really nice and at first glance, very innovative.

However, I do find logging food is a little challenging. I struggled to understand how to save food and meals for later (I wanted to pre-create some meals that I commonly consume). I don’t know if it was just me but it didn’t seem very intuitive compared to YAZIO and MyFitnessPal. So I thought that saving my meals or reoccurring foods so I can speak them to Siri would be 1000% easier. But when I log food via Siri, the data gets logged in the health app but nothing gets logged in the Today or Insights tabs of the One Drop app. Further, if I log food or meals via other apps that also connect to health, One Drop does not display the nutritional values from the health app, despite the One drop app being granted read access to that data. If you can fix this, your app is 5 stars!
