You Don't Have to Marry Your CGM–Explore the CGM Dating Scene!
Jeremy Pettus, MD swipes through the current continuous glucose monitor (CGM) lineup to see how much has changed since he last picked one!
Dr. Jeremy Pettus gets dumped by his continuous glucose monitor (CGM)…over text! The sensor signs off by sending him a link to CGMder, a dating app where CGMs have profiles and Jeremy can see what each one brings before he commits to something more serious.
When considering the best CGM device for you and your lifestyle, it almost feels like you are entering the dating game—you have to decide which traits matter to you, which ones you can live without, and how well the match works in real life. Nothing about the choice has to be permanent. You can try something new, switch back, or keep looking for the best fit.
That kind of flexibility is very recent. With today’s leading CGMs accurate enough to support insulin-dosing decisions, accuracy is no longer the deciding factor. The right choice is much more personal, including which insulin pump you use, your history with a sensor you already trust, help with basal insulin titration, personalized food-impact predictions, and next-generation continuous ketone monitoring that is moving closer to availability.

Islet cells produce insulin, amylin, and glucagon, not insulin alone, which is part of what makes replacing them so appealing.

Worth Knowing Before You Watch
- Islet cells do more than make insulin – they also produce hormones like amylin and glucagon that help the body manage blood sugar, which is why replacing the whole cell matters more than replacing insulin alone.
- The cells can come from two very different sources – donated tissue from deceased donors, which is a limited supply, or cells grown in the lab from stem cells, which offers offers unlimited access.
- Where the cells are placed matters – researchers are studying infusion into the blood vessel that feeds the liver, along with other sites like tissue under the skin and even muscle.
- The immune system is the central challenge – the body attacks transplanted cells, so every approach has to solve the problem of protecting them, and this is where the leading programs differ most.
- Durability is still an open question – even the most promising results raise the question of how long transplanted cells keep working, and that is one of the things researchers are watching very closely.

The eversense 365 sounds great for weartime but the implanting under my skin is where I draw the line, so I would choose the minimed instinct.
Thankfully we have several options, so everyone can choose the system that best suits their needs and lifestyle!
I love my Minimed Instinct. Although it requires no over tape I have knocked a few off in the past year. Minimed’s replacement program with Abbott has been satisfactory in replacing these sensors so I don’t lose the money spent on the sensor. I have also learned to help secure them with tincture of Benzoin aka, “gorilla snot”. They even survive going swimming.
Insurance cover this system

My wife passed and I drive 2-4 hours to visit grandkids.
How can I get my blood sugar information posted in car play or some other system to see information at a glance. I’m not very tech savvy.
I have not been able to find the new Libre 3 + Assist app in the Apple Store. I just received a shipment of six Libre 3 plus sensors in the mail and I read that they’ll be a new app to go with the sensor. Will the sensor change along with the app or just the app by itself?
Option 1: Native App / Dashboard Integration (Direct Method)
If you use the Dexcom G7 (or compatible native apps), you can view readings directly via app support or iOS widgets.
1. Update Your App & iOS: Ensure your CGM app (e.g., Dexcom G7) is updated to the latest version via the App Store.
2. Enable in CarPlay:
On your iPhone, go to Settings > General > CarPlay.
Select your vehicle under paired cars.
Tap Customize and add your CGM app (or its widget) to the active app list.
3. View on Screen: Connect your phone to CarPlay. Tap the app icon or swipe to the widget dashboard screen on CarPlay to view your current reading and trend arrow.
Option 2: The Calendar Sync Workaround (Most Reliable & Broadly Compatible)
Because Apple CarPlay natively displays upcoming calendar events on its Dashboard screen, third-party diabetes management apps use this to write real-time glucose readings directly to an active calendar. This works for Dexcom, Freestyle Libre, and Nightscout.
Thanks so much for posting!
Right now, just use the Libre 3 app, and you should be fine.
I switched to 365 eversense.. it is great, but it would be better if i had the pump the works with… i been going back and forth with the insurance and doctor for a bout 6 months now.
So sorry to hear that. Hope you get the insurance worked out soon.
