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.

Love this App

If I could give this app more stars I would. Keep in mind I never rated an app but I had to do one for this app. I recently (okay maybe two years now) I stopped being health conscious and taking care of myself but that all changed with this app. I’m logging in my medications and my daily routines. It always gives me a reminder to check my BG and it’s in a “encouraging way” nothing like it being a nag. I’m always looking forward to logging in my meals and medications then checking my results when I get my reminders! Thank you One Drop team I’m finally getting my numbers in check and I’m feeling the benefits! Keep up the good work and I’m looking forward to how you improve the app. I have only one tiny suggestion...I wish I could log in my progress and meds thru my Apple Watch but over all thank you for this app!!!!!!
