Apps are playing an increasingly large role in how people manage their diabetes. After all, between carb counting, weighing nutritional advice, and tracking blood sugar levels, both type 1 and type 2 diabetes require close attention. But apps designed specifically for diabetes care can save a lot of time and effort.

Here are our picks for some of the best diabetes-related iPhone and Android apps:

Sugar Sense—Free

Available for both iOS or Android, Sugar Sense lets you track your blood glucose levels, HbA1c, insulin, blood pressure, carbs, weight, and more in an attractive, easy-to-read interface. You can share reports with your healthcare providers and loved ones, find answers to diabetes questions, and automatically record how much you walk each day.

Glucose Companion Free

As the name implies, there’s no charge for this app. But like many other free apps, you can buy a paid version to add more features. Don’t be in a hurry to spend your money, though—there’s a lot to like in this free app for iOS. In addition to logging blood sugar, weight, and test data, you can see what your numbers mean with charts and statistics, add notes, create reminders, and calculate how much insulin you need to inject.

Glucose Wiz—Free

Another great free app for iOS, Glucose Wiz lets you track glucose readings, weight, medicine use, and more. Create multiple profiles and as many reminders as you like. Charts and reports help you see big-picture trends over time. And easily print or email your logs to share them with anyone you like.

Glucose Buddy—Free

Track your blood sugar and diabetes medications through Glucose Buddy for Android devices. With this app, you're able to manually enter glucose numbers, carbohydrate consumption, insulin dosages, blood pressure, weight, and activities. This app merges graphs, a logbook, a calculator, doctor printouts, and push reminders all in one.

Diabetes App—$6.99

With an enormous food database, the Diabetes App for iOS can tell you how many grams of sugar were in the pastry you just ate. For those struggling with diabetes care, this app may come in handy. It can help you make informed decisions about diet and diabetes treatment. Furthermore, it enables users to track their glucose levels, blood pressure, meds, weight, water intake, and much more.

MySugr Diabetes Logbook—Free

MySugr Diabetes Logbook, available for iOS and Android, tracks, measures, and gives you access to several different types of diabetes data. It syncs with your blood glucose meter, estimates your A1c, interprets your continuous glucose monitor (CGM) data, calculates your bolus (available in the European Union only), and counts your steps as your personal pedometer. As you’d guess, some features only come with the Pro version, available for $2.99 per month.

MyNetDiary—$9.99

MyNetDiary is available for iOS, and it's touted as the number one paid diabetes tracker app in the United States. This app helps you track and manage your diabetes or prediabetes, keep track of blood glucose, and control carbs. The makers state that, "Whether you had diabetes for years or you are newly diagnosed . . . MyNetDiary has all the tools to help you stay in control, eat better, and feel better."

They say that their online and app tracker has been used by more than 50,000 people, and an active user loses 12 percent of body weight on average. Additionally, the app's average self-reported A1c reduction is 1.4 percent.

Glooko—$59.95 per year

Sure, it seems spendy, but with Glooko for iOS or Android, you can sync your diabetes device to your smartphone to save time and reduce errors. (And here’s a bargain: if you use an OmniPod pump, you can get Glooko free!) The program is compatible with more than 50 meters, pumps, and continuous glucose monitors, as well as many popular fitness trackers. With an annual Glooko subscription, you will receive the required MeterSync device plus access to the free Glooko app for iOS or Android and the MyGlooko web app.
 
Glooko enables you to easily share your data with your healthcare team, including your doctor, family members, and nutritionists. There’s a glucose logbook, and reports include blood glucose averages, stats, and graphs. With the "Quick Add" feature, you can also jot down notes about your blood glucose readings.
 
Whichever app you choose, remember: apps don't replace your doctor; they are just a supplementary tool.
