Stelo is a biosensor that does not require a prescription, is available over-the-counter, and lasts for up to 15 days. The Dexcom G7 requires a prescription and lasts for up to 10 days, with a 12-hour grace period. With that said, Stelo may sound more beneficial; nonetheless, remember that the pros come with cons, and to understand all the positives and negatives of both glucose sensors, let’s dive into Stelo vs Dexcom G7.
Dexcom Stelo vs G7 Comparison
Among the major differences between Dexcom G7 and Stelo are the eligibility criteria, availability, accuracy, alerts (especially the low glucose alerts), and AID compatibility.
Eligibility, Availability, Accuracy, Alerts, and AID Compatibility of Stelo
The following are all the major aspects you may want to know about Stelo:
- Eligibility: Stelo is a biosensor indicated for people aged 18 and above who are not on insulin, i.e., type 2 diabetics (not on insulin), or anyone who wants to have good metabolic health. Moreover, there are no insurance coverage details on this biosensor yet.
- Availability: This biosensor is available over the counter (requires no prescription).
- Accuracy: As per the company, when compared to gold testing (fingerstick test), Stelo was found to be about 93% accurate. Some sources suggest that Stelo has a MARD (mean absolute relative difference) of 9.2%.
- IMP: The lower the MARD, the better the accuracy.
- Alerts: While Stelo does offer alerts, they are limited and are not specifically for saving you from adverse low or high blood sugar events.
- AID Compatibility: Stelo is not indicated for diabetics on insulin; it cannot be connected with automatic insulin delivery (AID) systems either.
Eligibility, Availability, Accuracy, Alerts, and AID Compatibility of Dexcom G7
The following are the major aspects of Dexcom G7 continuous glucose monitoring sensors:
- Eligibility: Indicated for individuals aged 2 and above with type 2, type 1, or gestational diabetes. Insurance coverage is available.
- Availability: Requires a prescription from your doctor.
- Accuracy: With a MARD value of 7.8%, Dexcom G7 still stays strong for people who are on insulin.
- Alerts: Not just high and low alerts, the Dexcom G7 sensor comes with predictive low alerts, especially saving you from adverse hyperglycemic events.
- AID Compatible: The G7 sensors are AID compatible and can be connected to some of the latest AID systems in the USA, e.g., Omnipod 5.
While the above are the most concerning aspects for someone looking to add ease to their diabetes management, individuals who do not prefer to even carry their phone may find it suitable to opt for a Dexcom G7 that offers a direct-to-watch feature, allowing you to leave the phone behind whenever you like.
Similarities of Stelo and Dexcom G7
- Glucose Monitoring Principle: Both sensors measure glucose continuously from interstitial fluid.
- Warm-up time: With 27 minutes for Dexcom G7 and 30 mins for Stelo, the warm-up time (before readings begin) of both sensors is under 30 minutes.
- External Transmitter: Neither Stelo nor Dexcom G7 requires a separate transmitter. Both come with built-in transmitters.
- Apps/smartphone connectivity: Both sensors have companion mobile apps (iOS, Android).
- Trend & pattern analytics: Stelo and Dexcom G7 both allow users to see glucose trends, spikes, and behavior correlations (food, exercise).
- Waterproof: Dexcom G7 and Stelo both can be submerged in water up to 8 feet.

Which One Should You Choose: Dexcom G7 or Stelo
- If you are type 2 diabetic or manage your sugar level with diet/medication and not using insulin, Dexcom Stelo OTC is likely an excellent choice. It gives you insights, helps you track how your lifestyle impacts glucose, and provides easier access with possibly fewer insurance hurdles.
- If you are type 2 or type 1 diabetic and manage your glucose level with insulin, or have frequent episodes of low blood sugar, go for Dexcom G7. The extra feature set is worth it.
Conclusion:
Stelo, a no-prescription and over-the-counter biosensor, is suitable for people who want to monitor their glucose levels but do not experience extreme low or high glucose. While the Dexcom G7 is suitable for a wide range of individuals aged 2 and above who are living with diabetes, who may require alerts to save themselves from extreme hypo or hyperglycemic events.

Unlike the Dexcom G7, which requires a prescription, Stelo will be available over the counter, making it more accessible for people without diabetes who still want real-time glucose insights.
How do Stelo and Dexcom G7 compare in terms of accuracy for glucose monitoring?
Stelo and Dexcom G7 offer very similar accuracy, with Stelo’s MARD at 8.3% and G7’s at 8.2%, meaning both provide reliable glucose readings close to actual blood levels. As a diabetic, you’ll get confident daily insights from either, but G7 edges out slightly for precise insulin management needs.
How much does the Stelo CGM cost compared to the Dexcom G7?
The Stelo CGM is 99 dollars in total which is less than the Dexcom G7, appealing to wellness users and those without insurance coverage. Pricing details will be announced at launch.

How reliable are Stelo glucose readings compared to Dexcom G7?
Early reports suggest Stelo offers competitive accuracy, though Dexcom G7 still holds the edge in medical-grade precision. Stelo focuses more on lifestyle tracking than clinical management.
What are the main differences between Stelo and Dexcom G7?
Stelo is over-the-counter for non-insulin users with 15-minute readings and no alerts, while G7 requires a prescription, offers 5-minute updates, customizable alarms, data sharing, and pump integration for all diabetics. For your management, Stelo focuses on lifestyle insights, but G7 provides advanced features like hypo/hyper warnings for better safety.
Who is the target audience for Stelo's FDA approval compared to Dexcom G7's?
Stelo is approved for adults 18+ with type 2 diabetes or prediabetes not using insulin and not prone to severe lows, focusing on lifestyle tracking. G7 targets all ages 2+ with any diabetes type, including insulin users, for comprehensive management and integration with treatments.
