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!!

Does the job...

I’ve been a One Drop customer for over a year now and really like the meter and lancets. They’re pretty for what they are and being on autoship is so convenient. I also like that the company replaces the meter annually to ensure you’re getting accurate numbers consistently.

The app, however, is just blah for me. I only use it to keep a running log of my numbers, which I only test twice a day. My meds are all in pill form once a day, so I don’t need to always know what my BG is like insulin users do. I also use a separate app to log my meds and supplements (the Round app) as I find it to be a better interface than OD offers. It’s just more simplistic. So basically I have the one drop on my phone just to Bluetooth my numbers from my meter. That’s it. I wish one drop offered a basic app for this purpose in addition to this one because I just find this app clunky. I don’t read the articles, log food, use the coaching, etc. I appreciate what the company is trying to do with this app and I know all of these extras probably help so many people, but I just prefer more simplicity when using an app like this. A separate lite version would be so great with just a blood glucose log for when I see my doctor and just want to show history without the other frills. Also less pink would be great, although I know that’s the company color.

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.
