In short.

Dexcom Stelo is the first-mover prescription-free CGM in the US, with growing built-in food logging and a 1M+ food database. SNAQ is the AI nutritionist that pairs with Stelo: photo carb counting validated at 5.5 g mean absolute error, glucose response prediction before you eat, and a published RCT on Time-in-Range improvement. Wear the Stelo sensor; use SNAQ to make sense of the data and decide what to eat next.

At a glance.

Dexcom Stelo is a 15-day OTC CGM with a clean companion app and growing food logging features.
SNAQ pairs with Stelo to add photo carb counting (validated at 5.5 g mean absolute error), predictive glucose response and AI coaching.
SNAQ has a peer-reviewed RCT on Time-in-Range improvement (eClinicalMedicine 2025).
Stelo is hardware-first; SNAQ is software-first. The two are designed to complement each other.
SNAQ also integrates with 19+ other devices, so a future sensor switch doesn't strand your data.

Structured comparison based on publicly available information, last reviewed May 2026.

Feature	SNAQ	Dexcom Stelo
What it is	AI nutritionist with predictive glucose model	15-day OTC CGM (hardware) with companion logging app
Photo meal logging accuracy	✅ Validated at 5.5 g mean absolute carb error	⚠ Smart Food Logging, accuracy not peer-reviewed
Glucose prediction before the meal	✅	❌
AI coaching	✅ Proactive	⚠ Smart daily insights
Cross-data pattern insights	✅ Across meals, glucose, insulin, activity and weight; weekly progression and simple summaries	⚠ Smart daily insights, glucose-focused in the current app
Peer-reviewed clinical evidence (product-specific)	✅ RCT, eClinicalMedicine 2025	✅ Sensor accuracy validated
Multi-device support	✅ 20+ devices (Dexcom, FreeStyle Libre, Eversense and more)	⚠ Dexcom-only data; integrates with Nutrisense, Apple Health
Sensor-optional use	✅ Works fully without a CGM or BGM; supports intermittent sensor wear	❌ Companion app, requires the Stelo sensor
Provider dashboard	✅ SNAQ Care for clinicians, includes meal, glucose, activity, insulin data and more, 500+ clinicians	❌ Stelo companion app is consumer-only, no clinician portal
Best for	Anyone wanting RCT-backed AI nutrition guidance	Prediabetes and T2D-non-insulin users who want easy OTC sensor access

Why users switch.

Stelo + SNAQ is the better combination

Stelo's app is intentionally light. SNAQ adds the predictive meal layer and the AI coaching that turns raw glucose data into decisions.

Future-proof your sensor choice

If you ever switch from Stelo to G7, Libre or another sensor, SNAQ keeps your meal and glucose history. Stelo's app does not.

Peer-reviewed evidence

Stelo's hardware accuracy is validated. SNAQ's clinical outcomes are validated in a randomised controlled trial.

Honest take.

Choose SNAQ if…

You want to do more with your Stelo data than view trends.
You want peer-reviewed evidence behind the AI guiding your decisions.
You might switch sensors or wear multiple devices.

Consider Dexcom Stelo if…

You only want the basic, clean Dexcom companion app and don't need predictive guidance.
You don't want to add a second app to your phone.

Bottom line

Stelo is the sensor; SNAQ is the intelligence. Most users get the most value running both, with SNAQ as the everyday app.

Frequently asked.

What's the main difference between SNAQ and Dexcom Stelo?

SNAQ is an AI nutritionist built around photo carb counting, predictive glucose response, and peer-reviewed clinical evidence (RCT published in eClinicalMedicine in 2025). Dexcom Stelo solves a different problem in the same broader category. The right pick depends on whether your priority is general logging or clinically-validated nutrition guidance for diabetes, prediabetes or GLP-1 use.

Is the clinical evidence for SNAQ independently verified?

Yes. The primary randomised controlled trial (NCT05671679) was published in eClinicalMedicine, a peer-reviewed Lancet journal, in 2025. Photo carb counting accuracy was independently validated by Bern University Hospital and published in JMIR mHealth in 2020 (Herzig et al.).

Which CGMs and devices does SNAQ work with?

SNAQ integrates with 20+ devices including Dexcom (G6, G7, Stelo), FreeStyle Libre, Eversense, Apple Watch, Whoop, Garmin, Withings, Samsung Health, OneDrop and OneTouch. You bring whichever sensor or wearable you already use.

Is SNAQ a Dexcom partner?

Yes. SNAQ has an official partnership with Dexcom and integrates directly with Dexcom G6, G7 and Stelo.

Do I need to choose between Stelo's app and SNAQ?

No. They serve different purposes. Stelo's app gives you the basic glucose trend and food logging. SNAQ adds photo carb counting, glucose prediction and AI coaching, while reading the same Stelo sensor data.

Can I use SNAQ if my doctor prescribes Dexcom G7 instead?

Yes. SNAQ integrates with Dexcom G6, G7 and Stelo. The transition from one Dexcom sensor to another is seamless on SNAQ's side.
