In late 2024, Oura announced a partnership with Dexcom, the maker of one of the most trusted continuous glucose monitors on the market. The goal — to integrate real-time glucose data with Oura’s existing sleep, stress, and recovery metrics.
That collaboration led to the release of the Stelo Glucose Biosensor — an over-the-counter CGM built on Dexcom G7 technology and adapted specifically for adults not on insulin therapy. For those already using Oura, this felt overdue: finally, a way to view glucose as part of the bigger picture, without jumping between apps.
Now it’s easier to spot patterns — how glucose responds to meals, activity, and poor sleep — alongside readiness and recovery data.
Stelo uses a discreet sensor worn on the back of the upper arm. It measures glucose in interstitial fluid approximately every 5 minutes and sends the data via Bluetooth to the Stelo app — and seamlessly into Oura if connected.
When paired, you can view glucose trends alongside sleep stages, heart rate variability, body temperature trends, and activity and movement patterns.
One standout feature is Time Above Range — which shows how long glucose stays above 140 mg/dL, one early indicator of metabolic dysregulation. Newer metabolic tracking also emphasizes Time in Range, glycemic variability, and glucose area under the curve — a more complete picture of how stable your glucose actually is throughout the day. Elevated or erratic glucose often correlates with poor sleep, sluggish recovery, or energy crashes.
For anyone tracking metabolism, this integration offers real-time awareness, not micromanagement. The value isn’t perfect numbers — it’s understanding how your body responds over time.
Stelo vs. Nutrisense: What’s Different
I’ve used Nutrisense in the past and found it insightful — but it required more active engagement, used a separate app, and strongly encouraged food logging. It also came with a steeper monthly cost.
Stelo felt simpler. It delivered the core data without the extra effort. You can log meals manually in the Stelo app, but it’s completely optional. If you’re syncing with Oura, you can also tag meals or add a photo using the Reflections feature.
Nutrisense may be a better fit if you’re looking for personalized guidance or are new to CGMs — their app emphasizes food logging, detailed analytics, and includes access to a credentialed nutritionist. They now commonly offer both Dexcom G7 and Libre 3 sensors depending on your plan. Stelo takes a more self-guided approach but includes a Learn tab with solid fundamentals on glucose metabolism.

What I Like About Stelo
Effortless Data Flow
Once the sensor is applied, glucose data updates automatically approximately every 5 minutes. No scanning. No missed readings. Just passive insight you don’t have to chase. Stelo relies on real-time Bluetooth, so it’s best to keep your phone nearby — especially during workouts or errands — to avoid dropped connections.
Seamless Oura Integration
For Oura users, this is the most useful feature. Glucose trends appear inside the Oura app, layered with sleep, HRV, temperature, and readiness. I noticed clear patterns — higher fasting glucose after disrupted sleep, more stable levels after movement and protein-forward meals.
Not an Oura user? You can still sync Apple Health or Google Fit data into the Stelo app for a broader view of glucose health.
Real-Time Alerts
The Stelo app sends alerts when glucose spikes. Last weekend, after a higher-carb dinner with dessert and a glass of champagne, I noticed an initial dip followed by a sharp spike just as I was getting ready for bed. With Spike Detection on, I got an instant notification.
Here’s why that happens: the body prioritizes metabolizing alcohol first, treating it as a toxin. While that’s happening, glucose production can be temporarily suppressed, leading to an early dip. Once the alcohol clears, the body shifts to processing the rest of the meal — often triggering a delayed spike hours later.
The next night, I went back to my usual dinner: a Shiraz salad with chickpeas, fish, and quinoa, followed by a sliced apple about two hours later. By the time I was heading to bed — roughly four hours after dinner — my glucose was holding steady around 90.
The real-time feedback was a good reminder: what you eat — and when — doesn’t always show up right away. The body often responds hours later, especially when stress, sleep, or alcohol are involved.
Over time, the patterns became clear. Carbs alone on an empty stomach — big spike. Walking after meals — significant drop. Alcohol — spike then overnight crash. Poor sleep or stress — elevated glucose without food. Smoothies — surprising spikes when low in fiber or protein.
Accessible Pricing
No subscription needed. Two 15-day sensors runs approximately $100 per month for real-time metabolic insight — most competitors charge over $200 with a required membership.
Accuracy
Stelo is built on Dexcom G7 technology, which is FDA-cleared and commonly used in clinical settings. Both Dexcom G7 and the FreeStyle Libre 3 have similar accuracy in independent studies, with mean absolute relative difference scores in the 8–9% range. The practical differences for non-diabetic users are minimal — both deliver reliable trend data for metabolic awareness.
Who Stelo Is Especially Helpful For
Stelo works well if you already use Oura and want glucose data in the same place, if you’re interested in blood sugar trends without logging every meal, if you’re refining your diet and want to spot patterns around crashes, cravings, or poor sleep, or if you want a lower-cost no-subscription CGM that still delivers meaningful data.
Used thoughtfully, tools like Stelo and Oura don’t tell you what to do — they help you listen. When you start noticing patterns instead of chasing outcomes, the data becomes less about control and more about understanding.
