Glucose tracking is stepping out of the diabetes-only box and into mainstream women’s wellness. Two standout over-the-counter options are Lingo and Stelo—both designed for women who want insight into energy dips, hormone shifts, workout recovery, and weight plateaus.
Lingo, powered by Abbott’s biosensor technology, leans into lifestyle optimization with an app-driven experience that translates glucose data into actionable nudges. It’s designed to help users understand how food, stress, sleep, and exercise impact metabolic flexibility—without the clinical feel.
Stelo, developed by Dexcom, brings the credibility of medical-grade CGM technology into an accessible, prescription-free format. It offers real-time glucose data in a simplified interface, making it appealing for women navigating perimenopause, insulin resistance, or curious about how their morning latte affects their blood sugar curve.
Both devices remove the guesswork—but the vibe differs. Lingo feels like a metabolic coach in your pocket, while Stelo offers straightforward glucose visibility backed by Dexcom’s long-standing CGM expertise. The best choice? The one that fits your lifestyle—and how deep you want to go into your data.
My Personal Experience: Stelo vs. Lingo
I tried Stelo first, and as a first-time CGM user, I appreciated how simple and intuitive the app felt. The setup was straightforward, the interface was easy to follow, and it even came with an adhesive sticker that made the sensor feel extra secure for the full 14 days. I’ll admit—those first few days, I was constantly checking my glucose, fascinated by how my body responded to meals, stress, and daily routines. One feature I really liked was the ability to take a picture of my meal and have it automatically upload with a visual and description. That made tracking effortless and helped me clearly connect specific foods to my glucose patterns.
When I transitioned to Lingo, the experience was slightly different. The app required a few more steps, and initially it felt a bit confusing. After watching a couple of instructional videos, however, I felt comfortable applying the sensor and navigating the platform. I ultimately liked the Lingo app a lot better overall—the insights felt more engaging and the experience more refined—but I did miss the photo-upload feature that Stelo offered. Physically, Stelo felt a little more bulky on my arm, while Lingo was more aesthetically pleasing and discreet.
The biggest surprise? White rice. Even when paired with protein, it spiked my blood sugar more than I expected. I’m already gluten- and dairy-free, and rice had been a grain I relied on heavily. I assumed potatoes would be the bigger trigger—but for me, rice was the real culprit. Additionally, I noticed that when I ate a high-protein meal as my first meal of the day, my blood sugar stayed more stable throughout the entire day. On mornings when I leaned more heavily on carbohydrates, my glucose trends were noticeably more erratic.
So are you thinking about trying a CGM? Even if you wear one for just 14 days, I truly believe you’ll learn so much about your personalized nutrition—what foods work for your body, what causes spikes, and how to create more stable energy throughout the day. For me, that level of insight made it completely worth it.
One challenge I experienced with both Stelo and Lingo was the Bluetooth connection. At times, the sensors would disconnect from the app, which was a little frustrating—especially when I had just eaten something and was curious to see how that specific food affected my glucose levels. Since those moments of curiosity are often when you most want real-time feedback, the occasional disconnect was something I had to navigate with both devices.
Here are two tips to focus when using your CGM
- Focus on patterns, not single spikes. This can be hard at first—especially when you’re excited and checking your glucose often—but it’s important to look at the bigger picture. Glucose naturally fluctuates throughout the day, so try to focus on overall trends rather than reacting to every individual reading.
- Prioritize protein and fiber with your first meal. Starting the day with protein can help stabilize blood sugar and reduce larger spikes later in the day. I also noticed that when I focused on eating enough protein and fiber, I felt fuller for longer and naturally reached for fewer snacks throughout the day because I had fewer cravings.
