In late 2024, Oura announced a long-awaited partnership with Dexcom, the maker of one of the most trusted continuous glucose monitors (CGMs). 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 designed for adults not on insulin therapy. For those of us 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 your glucose responds to meals, activity, and poor sleep—alongside your readiness and recovery data.
Stelo uses a discreet Dexcom G7 sensor worn on the back of the upper arm. It measures glucose in interstitial fluid every 15 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 (HRV)
- Body temperature trends
- Activity and movement patterns
One standout feature is Time Above Range, which shows how long your glucose stays above 140 mg/dL—a valuable early indicator of metabolic dysregulation. Elevated glucose often correlates with poor sleep, sluggish recovery, or energy crashes.
For anyone tracking metabolism or trying to lose weight, this integration offers real-time awareness, not micromanagement.
Stelo vs. Nutrisense: What’s Different?
I’ve used Nutrisense in the past and found it insightful—but it required scanning, used a separate app, and strongly encouraged food logging to get the most out of the experience. It also came with a steeper monthly cost.
Stelo, by contrast, felt simpler. It delivered the core data I wanted—without the extra effort. You can log meals manually in the Stelo app, but it’s completely optional. Logging isn’t central to the experience. 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. Stelo, meanwhile, takes a more self-guided approach—but includes a “Learn” tab with helpful fundamentals on glucose metabolism.
| Feature | Nutrisense | Stelo |
| Sensor | Abbott Libre (previously) | Dexcom G7 |
| Wear Time | 14 days | 15 days |
| Scanning Required? | Yes, every 8 hours if using FreeStyle Libre* | No scanning—data updates passively |
| Food Logging & Notes | Yes, with coaching | Optional in-app logging |
| Oura Integration | Not available | Yes – native sync |
| Price | ~$225/month with membership | ~$90/sensor – no membership |
| Target Audience | Data + coaching focused | Self-guided, insight-focused |
*Note: Nutrisense has recently begun offering Dexcom G7 sensors as well. At the time I used it, they were still using FreeStyle Libre, which required manual scanning.
What I Like About Stelo
Effortless Data Flow
Once the sensor is applied, glucose data updates automatically every 5–15 minutes. No scanning. No missed readings. Just passive insight you don’t have to chase.
Seamless Oura Integration
For Oura users, this is the real game-changer. Glucose trends appear right inside the Oura app, layered with metrics like sleep, HRV, temperature, and readiness. I noticed clear patterns—like higher fasting glucose after disrupted sleep, and 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 broad view of your glucose health.
Real-Time Alerts
The Stelo app sends real-time alerts when your 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 turned on, I got an instant notification.
Here’s why that happens: the body prioritizes metabolizing alcohol first, since it treats it as a toxin. While that’s happening, glucose production can be temporarily suppressed, leading to an early dip. But 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 go-to dinner: a Shiraz salad with chickpeas, fish or meat, 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, as shown in the Oura-synced glucose image above.
The real-time feedback was a good reminder: what you eat—and when—doesn’t always show up right away.
Accessible Pricing
No subscription needed. You pay for two 15-day sensors so you’re looking at ~$100/month for real-time metabolic insight.
Most competitors charge over $200/month with a required membership.
Accuracy
The Dexcom G7 is one of the most accurate CGMs available to consumers. It’s FDA-cleared and commonly used in clinical settings for diabetes management—which means its accuracy must meet strict standards.
Compared to the Freestyle Libre (used by Nutrisense in the past), Dexcom G7 offers:
- Faster warm-up (30 mins vs. up to 60)
- Better accuracy during glucose fluctuations (e.g., post-meal or after workouts)
- Lower MARD (Mean Absolute Relative Difference), meaning readings are closer to actual blood glucose levels
Who Stelo Is Especially Helpful For
- You already use (or are curious about) the Oura Ring and want your glucose data in the same place
- You’re interested in blood sugar trends—but don’t want to log every meal or track macros
- You’re refining your diet and want to spot patterns—like crashes, cravings, or poor sleep
- You’re looking for insight into how food, stress, and sleep may be impacting your weight
- You want a lower-cost, no-subscription CGM that still delivers meaningful data
