FreeStyle Libre 3 Plus: Difference from Libre 3 and whether switching is worthwhile

From the Zuckerschmuck team · As of: September 2026 · Reading time approx. 12 minutes

The Abbott FreeStyle Libre 3 Plus is the successor in the Libre 3 system: According to Abbott, you wear it for up to 15 instead of 14 days, and it is already approved for kids from age 2 instead of 4. The App, reader, warm-up period, and water resistance remain the same, and Abbott describes both sensors as having the same size, which of course suits us at Zuckerschmuck very well.

We get a little sentimental about FreeStyle Libre. In 2015, Sonja, who has lived with type 1 diabetes since the age of 7, got her first FreeStyle Libre, and as an aerobics instructor she wore it visibly on her arm: clinical white, right in the middle of her workout outfit. So she designed Stickers herself. The first designs were “all the rage” in a Facebook diabetes community and sold out within a few days, and that’s how Zuckerschmuck came about. Sonja now loops with the Dexcom G7, but Libre remains the sensor where everything started for us.

Now “Plus” appears on many packages, and with it come the questions: What’s different? Will insurance cover it? Do I need a new app? And do the Stickers still fit? We’ve gathered everything Abbott and the pump manufacturers say about it for you, with a source for every detail.

First things first, Diabuddies: All our Stickers and tapes for the FreeStyle Libre 3 also fit the FreeStyle Libre 3 Plus. So you can simply continue ordering your favorite designs.

What is the difference between FreeStyle Libre 3 and Libre 3 Plus?

Abbott names two differences in the sensor itself: the FreeStyle Libre 3 Plus can be worn for up to 15 days and is approved from age 2, while the FreeStyle Libre 3 can be worn for up to 14 days and is approved from age 4 [1][2]. In everyday use, there are two practical differences as well: who gets which sensor and which pumps Abbott lists for it. Operation of the Libre 3 Plus (also often written as Libre 3+ or simply 3 Plus) remains just as you know it.

Information: Abbott Diabetes Care [1][2][16][19][22], Tandem Diabetes Care [23].

Sounds like very little? Do the math: With a 14-day wear time, you get around 26 sensor changes per year mathematically, and with 15 days, around 24. Two fewer changes per year. But you don't have to commit to the same look for 15 days: Our stickers are easy to apply over the top if you'd prefer a new design after a few days. And Abbott makes no distinction regarding measurement accuracy: “Both sensors are accurate, but only the FreeStyle Libre 3 Plus sensor measures over a period of up to 15 days” [3].

Sonja has written down how the Libre 3 differs from the older Libre 2 in Freestyle Libre 2 vs. Libre 3.

Switching to the Libre 3 Plus: Prescription, health insurance and costs

Whether you get the Libre 3 or the Libre 3 Plus mainly depends on how you are insured in Germany. Since 15 October 2024, self-payers and private patients have, according to Abbott, received “exclusively the new FreeStyle Libre 3 Plus sensor” [2]. For people with statutory health insurance, Abbott states that “almost all statutory health insurers” cover the FreeStyle Libre 3, while for the Libre 3 Plus, Abbott is “gradually concluding contracts with statutory health insurers” [1][2].

For type 1 diabetes and type 2 diabetes treated with intensified insulin therapy, according to Abbott, all statutory health insurers and private health insurers cover the cost of a FreeStyle Libre glucose monitoring system, but the decision is made on a case-by-case basis [4]. If you have statutory health insurance, you pay up to 10 euros per month toward the sensors and a one-time fee of 5.99 euros for a reader [5]. Discuss whether and when to switch with your diabetes team, which will also issue the prescription.

Want to try the Libre first? In Germany, Abbott offers a free trial campaign with a trial sensor for adults with diagnosed diabetes and a German delivery address, once per person and no later than 31 December 2026 [6]. And if a sensor fails: Abbott accepts complaints online or via the free hotline 0800 519 9 519; you should have the sensor's serial number ready [7].

To be completely honest: We don't sell sensors. You can get the Libre 3 Plus with a prescription or, as a private patient or self-payer, directly from Abbott's webshop [1]. We have everything that makes it look better.

And what about Austria and Switzerland?

In Austria, according to Abbott, ÖGK, BVAEB, and SVS cover the costs for people with type 1 or type 2 diabetes using functional insulin therapy, basal-bolus therapy, or insulin pump therapy, provided they complete product training [8]. In Switzerland, according to Abbott, the system is listed in the list of aids and appliances (MiGeL) and is prescribed by specialists in endocrinology or diabetology [9].

Warning: Abbott notice about individual sensors

Abbott provides information on a dedicated page that a subset of FreeStyle Libre 3 and Libre 3 Plus sensors may display falsely low glucose readings [10]. There, you can check your sensor's serial number. If you have questions, the Abbott hotline or your diabetes care team can help.

App, reader, alarms, and sharing readings

You don't need a new device: According to Abbott, the FreeStyle Libre 3 Plus sensor is “compatible with the current version of the FreeStyle Libre 3 app and the FreeStyle Libre 3 reader” [1]. So just check the app store to see whether an update is waiting, and get started.

• Alarms: According to Abbott, the Libre 3 system offers optional alarms for low and high glucose levels, as well as a signal loss alarm that alerts you when there has been no connection for more than 20 minutes [12].
• Sharing readings: With the LibreLinkUp app, family members and caregivers can view readings, according to Abbott for up to 20 people [13]. This is an important feature, especially for parents of kids with diabetes.
• Smartwatch: Abbott does not currently offer a dedicated smartwatch app. However, some watches display smartphone notifications, including glucose alarms from the FreeStyle Libre 3 app [14].
• Sensors and reader: According to Abbott, the FreeStyle Libre 3 app and reader work with FreeStyle Libre 3, Libre 3 Plus, and FreeStyle Libre Select [11].

You use the reader? Then everything stays the same here too, and the reader can get a little makeover: with a bag for the reader, a protective case for the reader, or stickers for the Libre 3 reader.

Changing the sensor on Libre 3 Plus: Apply, warm up, dispose

Changing the sensor is our little ritual: old sensor off, new sensor on, favorite design added. With Libre 3 Plus, it works just like with Libre 3.

1. Choosing a spot: According to Abbott, FreeStyle Libre sensors are approved only for the back of the upper arm. You should avoid areas with scars, moles, stretch marks or swelling [17].
2. Preparing the skin: Abbott recommends washing the spot with fragrance-free soap, cleaning it with an alcohol wipe and allowing it to dry completely [15].
3. Applying: Unscrew the cap from the applicator and press the applicator onto the prepared spot [15].
4. Warm-up: According to Abbott, after activation the sensor is ready to measure after 60 minutes; calibration is not required [1][16]. That’s why many people schedule the change during a quiet hour rather than right before exercise or a large meal.
5. Disposal: According to Abbott Austria, the sensor contains a permanently installed battery and therefore does not belong in household waste, but in electronic waste. Take the applicator to a collection point for sharps, and put the packaging in the waste paper [18].

And then comes the best part: put on a Sticker, wrap it with tape, and your look is complete. And if you feel like trying something new in between, simply stick a new Sticker over it. Since one more day also means one more day of adhesive on the same spot, it’s worth checking your skin. If it itches or becomes red, you’ll find tips in Help with skin irritation from sensors, and if the discomfort persists, talk to your diabetes team.

On the go with the Libre 3 Plus: swimming, airport, MRI

Swimming pool, vacation, doctor’s appointment: Your sensor comes with you everywhere, but you should know a few rules from Abbott.

• Water: According to Abbott, the sensor is waterproof in up to 1 meter of water for up to 30 minutes, so showering, bathing and swimming are possible [19]. For summer, swimming pools and sweating, we have more tips in Sensor in summer.
• Airport: According to Abbott, you can pass through metal detectors with the sensor and reader without concern, but the system should not be exposed to certain full-body scanners using X-rays or millimeter waves. Abbott recommends transporting sensors in your carry-on luggage, keeping your medical travel certificate ready to hand, and informing security personnel about the sensor on your arm [20].
• X-rays, MRI, CT: According to Abbott, the sensor should be removed before these examinations, and a new sensor should be applied afterward [21]. So let your practice know in good time so you have a replacement sensor with you.

Libre 3 Plus with insulin pump and loop: what works, what’s next

For Germany, Abbott names the mylife Loop AID System with the mylife CamAPS FX App and mylife YpsoPump, approved for the FreeStyle Libre 3 and the Libre 3 Plus [22]. AID stands for “automated insulin delivery”, meaning a system in which the sensor, app, and pump work together. A lot is currently happening with many other combinations:

• Tandem t:slim X2: Since July 1, 2026, the pump has worked with the Libre 3 Plus in the United Kingdom, Switzerland, Sweden, Finland, and Italy. According to Tandem, more countries are to follow during 2026, including Belgium, the Netherlands, and Germany [23].
• Omnipod 5: Insulet reported compatibility with the Libre 3 Plus in the USA in June 2026; further international launches have been announced for later in the year, but Insulet does not name the countries [24].
• CamAPS Liberty: Manufacturer CamDiab describes the function as a fully closed loop for myLoop users, “coming soon” and “subject to local market approvals and availability”, intended for people with type 1 diabetes aged 13 and over and not during pregnancy [25].
• Medtronic Instinct: The MiniMed 780G is compatible with the Instinct sensor, which Medtronic says is manufactured by Abbott and can be worn for up to 15 days. The CE mark was received in March 2026, and the launch in the first European countries was announced for the summer [26].
• Libre Duo: In May 2026, Abbott received the CE mark for Libre Duo, a sensor that measures glucose and ketones. The launch in selected European countries has been announced for later in the year [27].

Which pump and system are right for you is a therapy decision. Talk to your diabetes team about it. By the way, Sonja describes what switching sensors feels like in everyday life in her Dexcom G7 experience report.

Libre 3 Plus accessories: Do Stickers, tapes, covers, and armbands from the Libre 3 fit?

Yes. All our Stickers and tapes for the FreeStyle Libre 3 also fit the FreeStyle Libre 3 Plus, because Abbott describes both sensors as having the same size [1][2]. Our accessories are jewelry and decoration for both sensors, even if some products still say “Libre 3”.

A sensor doesn’t have to look like a hospital device. It can show who you are: playful, simple, brightly colored, or very subtle. You can find everything for the FreeStyle Libre 3 Plus in the Abbott FreeStyle Libre 3 collection. Our favorites:

• Sticker: The Stickers for the Libre 3 and Libre 3 Plus go on the top of the sensor and turn the small circle into a statement, from fruit to a Wi-Fi symbol. And you can simply stick them over again as often as you like. That's exactly how it all started for us in 2015.
• Tapes: The border tapes with a hole form a decorative ring around the sensor, for covering it up or showing it off.
• Cover: New are the jewelry covers for FreeStyle Libre 3 and Libre 3 Plus in a set of 3, with three colors to switch between. The TapeCover from the cover collection sits between the sensor and tape and makes it easier to change the tape during the wear time - practical if you want to change the design once during the 15 days.
• TapeGuard: With the TapeGuard applicator, you can apply border tape to the back of your upper arm without help from someone else.
• Armband: If you prefer wearing a band, you can find an elastic armband with holder. One-piece or interchangeable band? We compared them in Freestyle Libre sensor holders.

Are you wearing other technology too, such as a Dexcom G7 or the Libre 2? You can find everything you need for that under Accessories for CGM sensors.

FreeStyle Libre 3 Plus experiences: What Diabuddies report

We don't have our own long-term test with the Libre 3 Plus, so we won't tell you any made-up stories here. However, we looked through German-language diabetes forums to see which topics keep coming up when switching:

• The shifting change day: Because each sensor runs for one day longer, the change day moves forward by one weekday each cycle. If you like to always change on Sundays, you will have to get used to it.
• The skin: Some people report that their skin reacts more sensitively over the longer wear time. So it is worth checking your skin regularly.
• App and phone: There is repeated mention of necessary app updates and questions about phone compatibility. Abbott provides a compatibility list at freestylelibre.de.
• Readings and connection: Some posts deal with discrepant readings or connection interruptions. If you notice anything like this, Abbott's hotline and your diabetes team are the right people to contact.

Are you already wearing Libre 3 Plus? Feel free to tell us how the switch went for you and which design is currently on your sensor.
