13 Best Glucose Monitoring Apps

With the rise in accessibility to continuous glucose monitoring (CGM) technology, tracking blood sugar levels has never been easier. But tracking glucose isn’t just about numbers and glucose data graphs—it’s about empowering yourself with the knowledge and insights you need to regain control over health, break free from dieting cycles, and find sustainable, personalized solutions.

With multiple CGM apps available, from the Nutrisense App to Dexcom G7 App, Stelo App, Lingo App and more, choosing the right one can feel overwhelming. How do you choose? Which one will really help go beyond blood glucose readings to help you truly understand your blood sugar response?

Nutrisense glucose experts, who have experience working with data insights from 100,000 CGM users, got together to rank some of the best blood glucose monitoring apps and CGM apps to help you make an informed decision. Here's everything you need to know about the best glucose monitoring apps of 2025.

Who Can Benefit from Glucose Monitoring Apps?

You may think blood sugar monitoring apps are mainly for people with conditions like type 2 diabetes or those with prediabetic glucose levels.

Today’s best CGM apps offer more than blood sugar readings. They’re like all-in-one health apps with meal comparisons, real-time tracking, access to professional nutritionists, and AI-powered insights that help you optimize your diet, physical activity, stress, and sleep habits.

And while some blood sugar apps cater only to managing diabetes or prediabetes or just to view CGM data readings, others offer app features for whole-health benefits like:

• Weight loss and metabolic health tracking
• Understanding food's impact on your unique blood sugar levels
• Optimizing physical activity and energy levels
• Improving sleep, mood and stress management

Some apps, such as the Nutrisense app, even offer the option to pick from support options like insurance-covered dietitian calls, so you can pair your continuous glucose monitor (CGM) readings with expert advice, for the most accurate and far-reaching insights into your health.

Best Types of Apps to Understand Your Blood Sugar Levels

If you type “glucose” into the app store, dozens of apps will fill your search list. Although this article focused on the best blood sugar monitoring and diabetes apps to download onto your mobile device, let’s take a look at the three major categories of glucose apps so you can understand more about how we picked:

• CGM apps
• Food tracking apps
• Apps for people with diabetes

Continuous Glucose Monitoring Apps

CGM apps such as the Nutrisense app pair with a CGM sensor to provide you the most accurate, up-to-date data about your blood glucose levels. With a CGM app, you can view how your food, exercise, stress levels, or sleep impacts your day-to-day life.

Food Tracking Apps

Just like the name suggests, food tracking apps allow you to log food, macro and micronutrients and so on to better understand your eating habits. Whether your goal is to stick to a diet or determine how your nutrition impacts your well-being, these apps can come in handy. Some apps also have blood sugar tracking!

Apps for People Who Already Have Diabetes

The primary feature among diabetes-focused apps is insulin management, which is not usually available in other blood sugar apps. These are best suited for insulin users or type I and gestational diabetes patients.
