Smartphone Apps for Diabetes Management

Written by: Abby Herrick, RD, LD, RCEP

Smartphones can help you manage your diabetes in ways that used to be complicated or time-consuming. Now, rather than writing your blood glucose (BG) levels on a piece of paper you can simply enter them into your phone, which analyzes patterns and comes back with recommendations for you.

There are a wide range of applications (“apps” for short) that can easily be downloaded to help you stay within your target range.  Each app comes with a variety of features relating to nutrition, exercise, and blood glucose to help electronically manage your diabetes. Today, you can download apps for smartphones, tablets, and iPods that let you record, store, and analyze information electronically, all in the palm of your hand. Some apps are free and others can cost a couple of dollars. Blackberry users also have apps, though this article will focus on those available to Apple and Android devices.

Can apps really help me manage my diabetes?

Instead of logging when and what you eat, medications, blood glucose, and exercise activity on separate documents or sheets of paper, many apps allow you to enter all of this information into one program. Besides personal health management, one benefit of using apps is that it is easier to share information with your healthcare provider. A study conducted by the Journal of Diabetes Science and Technology showed that apps benefit patients by showing trends of blood glucose over time. This invaluable information helps the user make informed decisions about how to improve their blood glucose management.       

What are diabetes apps?

  • Apps are programs that run on your smartphone, tablet, iPod Touch, or desktop computer and can perform tasks like storing information about your diabetes, finding patterns, generating graphs from your data or providing exercise or nutrition recommendations based on your lifestyle.
  • There are many diabetes apps available – some better than others – and if you’re already using a smartphone, it’s likely that you can easily start downloading apps today.
  • Apps install within seconds with one click of a button and there is no need to restart your browser or computer to begin using them.
  • Many apps can be used in conjunction with glucose meters and insulin pumps.

How do I download an app?

How do I know which diabetes app is right for me?

Finding the right app depends on which area of diabetes management you would like to address.

  • Focus on the area you struggle with the most. If you don’t always remember to test your blood sugars, then you will probably want an app that allows you to set reminders to test after your meals.
  • Decide if you want a general diabetes app or an app with a specific focus. The general diabetes apps are a one-stop shop in that they allow logging of so many different things. On the other hand, they may be overwhelming for somebody who is just starting out or they may have too many unnecessary features. (Keep in mind that if you decide to go with a focused app, you might need to track your blood glucose values in another place, like a second app, the software that came with your meter, or good old fashioned pen and paper.)
  • Once you have narrowed your options down to several apps, you can read user reviews (found at the Apple or Android website) to see what others like and dislike about each one.
  • If you don’t like the app you”ve downloaded, we encourage you to give it 2 weeks before switching. It may grow on you. And most apps have a help menu or a support forum where you can ask questions. They can help you get started or locate a feature that you might have missed.
  • If you’re still not happy with it after 2 weeks, you can always delete it and download a different app. As we’ve seen, your options are endless!

Choose an app (or several!) to help manage your diabetes

Improvements in diabetes software and advancements in technology will continue to make monitoring and managing diabetes easier.  If you”ve given it a go and decide that diabetes apps are not for you, there are other effective options available to track your diabetes information such as computer software, accessing web-based programs and downloading from your meter to a website just to name a few.  Technology has made living your best life with diabetes even easier with just a push of a button.

Do you have any of these apps on your phone? Or do you use another app to help manage your diabetes? We”d love to hear about your experiences! Please share in the comments.
