The FreeStyle Libre sensor has become an integral part of the daily lives of people with diabetes. It has come to symbolize freedom from finger pricks, continuous monitoring, and confidence in every day. However, times are changing, technology is advancing, and Abbott has taken a major step forward—the decision has been made to discontinue the basic models. The classic versions 2 and 3 will no longer be available. Instead, only the upgraded models—Libre 2 Plus and 3 Plus—are now available.
The original second- and third-generation systems gained popularity thanks to their ease of use, lack of calibration requirements, and simple operation. But every technology eventually needs an update, and it became clear to the manufacturer that further development is only possible on a new platform.
The company is now focusing all its efforts on supporting and producing the “Plus” models. Older devices will no longer be manufactured and will therefore eventually disappear entirely. This decision is driven not only by logistics but also by technological progress—newer devices offer precision, reliability, and functionality that were unavailable in previous generations.
On the surface, the changes may seem minor, but they significantly impact the user’s quality of life. The new FreeStyle Libre models last 15 days, rather than 14 as before. This means you can reduce the number of replacements by at least two per year, resulting in less hassle and lower costs.
In addition to improvements that are immediately noticeable, the updated models also include less obvious but important changes. For example, the adhesive layer has been reformulated: it now adapts better to different skin types and causes less irritation, even during prolonged wear. It also uses advanced measurement technology—the sensor analyzes interstitial fluid with greater accuracy, especially during sudden spikes in blood sugar.
Early user reviews of the new versions are generally positive. People note that the sensor stays in place more securely, the app runs smoothly, and the Bluetooth connection remains stable. Many emphasize that the extra day of battery life has been an unexpectedly pleasant bonus—it truly reduces the number of times you need to handle the device throughout the month.
Both versions provide equally accurate and stable readings but differ in how they’re used. The choice depends on an individual’s lifestyle and habits.
| Criterion | 2 Plus | 3 Plus |
| Requires a reader (not a smartphone) | Yes—you can use a card reader | Yes—a card reader can be used |
| Used to the classic layout | Yes—the interface is similar to previous models | Yes—the interface is similar to previous models |
| Maximum compactness | Standard size | The smallest sensor on the market |
| Suitable for children and teens | Suitable, especially with a reader | An excellent choice due to its size and automation |
| Bluetooth with data transfer | Yes, but the app is updated less frequently | Yes, data is transmitted every minute |
| Installation and replacement | Manual, same as before | Manually, same as before |
| For conservative users | Optimal | Less familiar |
| For active and tech-savvy users | It will work, but there are limitations | The ideal choice—minimal intervention |
If you’re tech-savvy, use your smartphone as your primary monitoring tool, and value minimalism—choose the Libre 3 Plus. If, on the other hand, you’re used to traditional controls and want to keep the option of using a reader, the Libre 2 Plus is a better fit for you.
Upgrading to the Plus model opens up a whole new level of control for people with diabetes. So if you’re just planning to start using the system, go straight for the new models. They’re designed to give you more freedom, confidence, and comfort in managing your diabetes.
