What Abbott’s 'Lingo' is (and what it is not)
Abbott’s Lingo glucose biowearable is now on Android, but it has no low alarms and is not a CGM for type 1 diabetes. Here is what it is, and what it is not.
You might see Abbott’s Lingo on sale and wonder if it is a cheaper glucose sensor for your diabetes. It is not. Lingo is a consumer wellness sensor aimed at people who do not use insulin, it has no alarms for low glucose, and it is not designed for type 1 diabetes. In December 2025 Abbott added Android support, which is why it has been in the news. If you have type 1, the sensor to rely on is the medical CGM your team prescribes.
- Lingo is a consumer biowearable (an over-the-counter glucose sensor sold for general wellness), not a medical device for diabetes.
- It has no low-glucose alarms, so it will not wake you or warn you if you are dropping, which a prescribed CGM (continuous glucose monitor) does.
- It is sold in the UK, but for people who are not on insulin, so sitting on a shelf here does not make it a type 1 tool.
- The recent news is simply that Lingo now works on Android phones as well as iPhone.
What Lingo is designed for
Lingo is what Abbott calls a biowearable: a small glucose sensor you buy over the counter, aimed at people curious about how food, activity and sleep affect their glucose. It is a wellness and metabolic-health product for a general audience, most of whom do not have diabetes and do not take insulin. The December 2025 update that put it in the headlines just added support for Android phones, widening who can use the app.
On the surface it looks a lot like the sensors people with type 1 wear, because it uses similar technology to read glucose under the skin. That surface similarity is exactly why it is worth being clear about the differences.
Why it is not a type 1 device
The key gap is safety. A prescribed CGM for type 1 is built to alarm when your glucose is low or dropping fast, and that is the feature that protects you overnight and during a hypo (a low, glucose under 4 mmol/L). Lingo does not do that. It is not intended to guide insulin decisions, and it is not a substitute for the sensor your diabetes team gives you.
None of this is a knock on the technology. It is simply built for a different job and a different person. If cost or access to your prescribed CGM is the reason a consumer sensor looks tempting, that is a conversation to have with your diabetes team, because there are proper routes to the right kit rather than relying on a device with no low alarm.
