I'm happy at the prospect of more accurate readings. But honestly, the Libre 3 is already simply excellent and I would personally prefer the back of the arm location to more wrist based tech. I wear a traditional (Citizen) mechanical watch, because I hated needing to charge a smartwatch. I had some issues with the Libre 2 sensor getting knocked off or loosening after a few days in the shower. But the libre 3 is smaller than a US quarter coin and lasts 15 days and doesn't snag on anything. Will this watch exceed that? Because if not, then I'm not looking to switch. Lastly for diabetics or pre-diabetics that are only using finger sticks, I CANNOT stress enough how important a CGM is to your health. You learn so much about how your body actually works with certian foods rather than low frequency (but somewhat more accurate) finger sticks and that information dropped my A1C like a rock in just a few months. Tell your older relatives also. These are life saving devices.

Yes, thanks for asking. Continous Glucose Monitors (CGM). That used to be a diabetic-only problem until Abbott, Dexcom,and other vendors expanded their markets beyond diagnosed diabetics into pre-diabetes markets and exercise, health, and well-being applications like: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10635370/ and: https://www.levelshealth.com/ This has exploded beyond the hundred years of ketogenic research and as research on glycemic variability in mental health has grown. My current kit includes an Apple Watch series 9 and an iPhone SE. Prior to that it was Google Pixel and a Fitbit Sense, though direct BTLE->Watch was not an option in that generation. I have two complications: Abbott Freestyle Libre 3 and Dexcom G7. Continuous Glucose Monitors (CGM). The Dexcom is entirely proprietary. The Abbott is accomplished via a series of 3rd party hacks: https://www.youtube.com/watch?v=YqUZjXo5VXY I'd say open source, but I'm not certain that every link in the chain is open source. I've run many generations of various open source tools on Android and iPhone since no vendor ships a complete end-to-end solution that is perfect. Nightscout and watchdrip are two open source examples: https://nightscout.github.io/ https://watchdrip.org/ When G7 originally shipped last year, sensor data left the sensor and used the iPhone as a proxy-to-cloud storage, as has become the default mode across many IoT devices because it was easy, obvious, despite the unintended consequen…

I almost completely forgot about the monitor itself, and only paid attention to the numbers on my phone. It's that unobtrusive (at least the Libre 3 one that I used). I let the needle (actually: annulus? see sibling comment) get into my head because I was curious and looked at it. It looks a lot scarier than it is, kind of like using contact lenses for the first time: before you've used them, you get into your own head about it, but once you've done it a couple times it's just rote and easy. I had started the first one a day before I started a few weeks of (6-days-on, 1-day-off) keto. Keto guides will say that you should have edit: One more thing, I used this time to play around with various sugar substitutes and see how they affected my blood glucose. Allulose came out as the winner (if money is no object) based on not having any noticeable off-taste or aftertaste and on measuring gram-for-gram the same as sugar (well sort of, it's only like 80% as sweet as sugar, so you get the same mechanical effects of sugar if you weigh it gram-for-gram and your baked goods or whatever come out not quite as sweet, which is perfect for me. Creaming butter with liquid stevia extract or something just plain doesn't work.

I have a Libre3 CGM. It works pretty well, except for the fact that it frequently loses Bluetooth connectivity to my phone. I can confirm that being more aware of the results you get when you eat the wrong food can be a strong incentive to help you choose better food.

I briefly used the libre 3, and found it very accurate (but was skeptical as the 2 and 1 could not even warn you about a low/we're passive) and durable. Currently on the Dexcom G7, waiting for support for either of these with my pump. The libre3 and G7 seem to be leaps and bounds better than anything else I've used (G4, G5, Guardian 3). I hope you two find something that works well!

Very cool! I'm currently wearing a CGM. I already love these and find them super non-invasive (Freestyle Libre 3). It's a penny that sits on your arm and every 14 days you change it for 1 minute. But this would probably be even cooler. Do you think there would be other locations that lend themselves to this, besides ear canal? People already use their ears for headphones a lot, so it might be difficult to use for some.

Current CGMs (Continuous Glucose Monitors) are amazingly non-invasive and easy to use. I'm wearing one right now and I can't feel it. I'm using the Freestyle Libre 3. It's the size of a penny on my upper arm. I don't have to replace it for 14 days, so I'm only really aware of it 2x per month. It transmits the signal to my phone via bluetooth. So essentially it's like your phone reads your blood glucose live but every 14 days you need to wipe your upper arm with an alcohol wipe and stick a new one in. The process is completely painless and takes 1 minute or so once you've done it a few times. Any doctor can prescribe you a CGM and they're like $70-100 per 14 day period, depending on brand/location/insurance. If you're diabetic your insurance will likely pay for it. Should you be on the fence I absolutely recommend you just get one. Pay it out of pocket just to learn how you respond to the things you eat and drink.

It's no longer watch-sized. The Freestyle Libre3 monitor is precisely the same size as a pair of stacked pennies (US). I'm wearing one right now. The previous Libre2 sensor was much larger, and you had to tap your reader device against the sensor in order to transmit data via NFC. In contrast, the Libre3 transmits via Bluetooth, and does so once per minute, without me having to do anything else. The non-insurance retail cost is about $70 per sensor. With insurance, it can be much lower. For me, the size difference is a real game changer. This thing is so much easier to wear and live with. For me, the automatic update once per minute is also a real game changer. I don't need to tap the sensor with my phone to get a reading, I just open the app on my phone and the data is already there. By all accounts, the Dexcom G7 is about the same size, and because Dexcom plays nicer with other devices, that's the way you want to go if you're trying to close the loop on the CGM plus automatic insulin dosing. For now, I'm super happy to have the Libre3. The app needs some improvement, but this is already a World Series + Super Bowl winner.
