Self-monitoring of glucose (blood sugar) levels at home may be an important part of diabetes care for some people. But with so many glucometers (glucose meters) available, how do you know which tool is right for you? Choosing the right device can feel overwhelming, especially with the wide range of new technologies.

The best glucometer for you depends on your lifestyle, budget, and preferences. This article compares two popular brands — Accu-Chek and FreeStyle — to help you weigh the pros and cons. Other well-known options include OneTouch, Contour, and Bayer.

Options: What Kinds of Devices Do They Offer?

Each brand offers several types of glucose meters. Some models are newer and more advanced, whereas others are simpler.

The Accu-Chek website currently lists three meters:

• Accu-Chek Guide — Uses test strips and connects to the MySugr app
• Accu-Chek Guide Me — Also uses test strips and connects to MySugr
• Accu-Chek Guide Link — Connects with the Medtronic MiniMed hybrid insulin pump

All three models use the Guide technology, which the company reports is their most accurate to date. Accu-Chek Aviva, an older model, is not currently offered on the company website.

FreeStyle offers both continuous glucose monitors (CGMs) and traditional meters. Options include:

• FreeStyle Libre 2 Plus and Libre 3 — CGMs that use sensors worn for up to 14 days. These models provide real-time glucose data and can connect to some insulin pumps.
• FreeStyle Optium Neo — A traditional meter that uses a test strip and a single-use lancet (a small, sharp tool to prick the skin)

The company website notes that the FreeStyle Libre 2 is being discontinued and replaced by the Libre 2 Plus, which offers updated features.

The Takeaway

If you want the latest in diabetes tech — like CGMs, insulin pumps, and fewer fingersticks — FreeStyle has more high-tech options. If apps and upgrades aren’t for you, Accu-Chek offers plenty of accurate, reliable meters.

Accuracy: How Well Do They Monitor Blood Sugar?

“Do you ever wonder if your meter is giving you an accurate reading?” one DiabetesTeam member asked. Accuracy is one of the most important features of any glucose meter. You rely on your device to give you blood sugar readings you can trust. If a reading is wrong, you may take too much or too little insulin or miss signs of high or low blood sugar.

Both Accu-Chek and FreeStyle are known for providing reliable results, though accuracy can vary slightly by model. A 2016 study comparing 17 glucometer models found that the following meters had no significant differences in accuracy:

• Accu-Chek Aviva Plus
• Accu-Chek Nano
• FreeStyle Freedom Lite
• FreeStyle Lite

All four models met international performance standards for blood testing. However, the study noted that each was slightly less accurate at detecting hypoglycemia (low blood sugar) than at measuring normal or high levels.

A more recent study of over 200 Accu-Chek Performa meters found that 100 percent met international accuracy standards. In another study of real-world use, FreeStyle Libre sensors, which are worn on the body, were slightly less accurate than standard finger-stick glucose testing at extremely high or low blood sugar levels.

The Takeaway

Both Accu-Chek and FreeStyle offer meters that provide accurate results, especially at normal blood glucose levels. However, sensor-based devices may be less reliable when your blood sugar is very high or very low. If your CGM or sensor gives you an unusual reading, check it with a traditional finger stick to be safe.

Ease of Use: Which Is More User-Friendly?

If you’re using your glucometer long term to manage your type 2 diabetes, it’s important to choose one that feels easy and comfortable to use.

Accu-Chek Guide is a traditional meter with a straightforward process. You place a small blood sample on the edge of a test strip, insert the strip into a lit-up port, and get a quick reading. You push a button to eject the used strip.

The FreeStyle Libre 3 involves a small sensor that’s applied to your skin and worn for up to two weeks. The sensor automatically tracks your blood sugar levels and sends the data to a smartphone app.

Both brands offer clear, step-by-step instructions online. For example, the FreeStyle Optium Neo website includes illustrations and videos that walk you through the process of using the device.

The Takeaway

If you’re interested in continuous glucose monitoring and want to avoid finger sticks, the FreeStyle Libre may be a better fit. If you prefer a traditional, hands-on approach, Accu-Chek Guide may be a good choice.

No matter which you choose, check the manufacturer’s website for detailed instructions and support. If you ever feel unsure, don’t hesitate to bring your device to your doctor’s office and ask for help.

Display Readability: Can You Interpret Your Results Clearly?

If you have trouble reading tiny numbers on a small screen, you know that a clear, easy-to-read display can make a big difference. Depending on your needs, it may also help to have your glucose readings automatically stored in an app on your phone or tablet. Here’s how the two brands compare in readability:

Accu-Chek Guide features a large, bright display with bold, easy-to-read digits — a helpful feature for people with visual impairments. The backlit screen allows you to check numbers even in low light. The newer Accu-Chek meters also link to the MySugr app (available for Apple and Android devices), which automatically logs your readings and helps reduce the chance of tracking errors.

FreeStyle Libre 3 system displays your glucose data through the LibreLink smartphone app (available in the App Store and Google Play), which offers a clear, easy-to-read interface. The app works in real time to show glucose trends and store readings. Another feature, the LibreView system, allows your healthcare provider to view your blood sugar information remotely.

“I like the ability to check on my blood sugars whenever I feel I need to,” one DiabetesTeam member shared. “I can also see how what I ate affected my sugars.”

The Takeaway

Both Accu-Chek and FreeStyle make it easy to read your glucose results, whether on a device screen or in an app. If you want a straightforward meter and the ability to manually add diet or exercise details, Accu-Chek is a good option. If you’re looking for real-time tracking and sharing with your healthcare provider, FreeStyle Libre can be helpful for tight control of your diabetes.

Cost Considerations: What About Price?

Glucose meters vary widely in price, and cost can be an important consideration.

Accu-Chek devices are typically less than $30 up front, but you’ll need to factor in the ongoing cost of lancets and test strips. Some insurance plans help cover these expenses. For example, Medicare Part B covers diabetes testing supplies with a prescription. Call your insurance company or check their website to confirm your plan’s details.

FreeStyle systems tend to cost more to start. The CGM sensor needs to be replaced every two weeks, which adds up. FreeStyle estimates that people with insurance pay an average of $1 a day for sensors, and for people with private insurance, the first sensor may be free. Visit the FreeStyle website to learn more about insurance coverage and savings offers.

Keep in mind that diabetes technology changes often. New models become available, and older ones may be phased out. One member shared their experience: “I use the FreeStyle InsuLinx meter, and the pharmacy no longer carries the control solution. I don’t want to change meters, but it’s looking like I might end up having to!”

Managing diabetes is a lifelong process, so it’s helpful to take into account the cost of replacements and future upgrades.

The Takeaway

Accu-Chek devices are generally more budget-friendly up front, while FreeStyle offers newer technology that may cost more over time. However, insurance coverage, savings programs, and manufacturer discounts can make both brands more affordable.

How To Choose the Right Option

In the end, the best blood glucose monitoring system is the one that works for you. Your decision may depend on your diabetes management goals, comfort with technology, and budget for diabetes supplies. If you prefer a traditional meter with quick, accurate results and a simple set-up, an option like Accu-Chek Guide might be a good fit. If you want real-time tracking without fingersticks and like the idea of data syncing with your phone, you may prefer a model like FreeStyle Libre 3.

There are many options for tracking your blood glucose levels — and no one-size-fits-all answer. If you’re not sure where to start, talk with your healthcare provider. They can help you find a device that fits your lifestyle, your medical needs, and your long-term diabetes care plan.
