Lingo

Abbott's Lingo is an over-the-counter continuous glucose monitor for non-diabetic and wellness consumers, built on Abbott's FreeStyle Libre sensor platform (FDA 510(k) K233655, decided May 29, 2024; Class II integrated CGM): a disposable biosensor worn up to 14 days on the back of the upper arm. It is the adaptive-algorithmic end of the glucose cell, the documented contrast to Stelo's generative AI: the app's 'Lingo Count' daily glucose-spike metric with adaptive targets, food and activity logging, and rule-based personalized recommendations are adaptive-algorithmic, not generative. 'Lingo Live' is free roughly 30-minute sessions with human Abbott nutritionists, not an AI coach, and DEPLOY surfaces that distinction prominently. Pricing starts at about $54 for a 2-week single-biosensor plan, with recurring biweekly and monthly multi-sensor tiers. From Abbott (NYSE: ABT). Cap-flag: the cleared indication is adults 18+ not on insulin, explicitly NOT for diagnosis of any disease including diabetes.

Privacy

Privacy practices disclosed by Abbott for Lingo, with verification status.

• Biometric storageverified

  The sensor streams your glucose levels every minute around the clock to the Lingo app and cloud. By using the service, you grant Abbott a worldwide license to use, reproduce, and modify that data to provide the product.

notes

• Boundary INCLUDE (narrow) - glucose-biometric + adaptive insight layer: Glucose is in the biometric definition; Lingo is biometric-primary (interstitial glucose). It clears the medical-sensor-without-meaningful-AI exclusion bar on INSIGHT-LAYER substance: Lingo Count with adaptive targets, algorithm-driven personalized food-response recommendations, and Challenges are the differentiator vs a bare CGM graph (which Abbott deliberately does not sell to this wellness audience). Would it exist without the insight layer? Yes-and-meaningfully-degraded -> above the thin-AI floor. Second example of the GLUCOSE cell alongside Stelo.
• Cap-flag: NOT at Stelo parity (AI is adaptive/algorithmic, NOT verified generative): Critical distinction: Dexcom Stelo cleared the bar with a GENUINE generative-AI layer (Google Cloud Vertex AI + Gemini Weekly Insights). Lingo's primary sources describe adaptive / rule-based personalization only - no documented generative-AI layer, no 'Lingo Coach' AI agent (coaching is algorithmic plus human nutritionist via Lingo Live). Do NOT grant Lingo Stelo-equivalent AI standing. It passes on insight-layer substance, not on generative-AI grounds; this is the borderline case of the cohort and is flagged as such.
• FDA anchor: FDA 510(k) K233655 decided May 29 2024; OTC integrated CGM; adults 18+ not on insulin; explicitly not for diagnosis of any disease. Directly parallel to Stelo's OTC posture (Stelo = De Novo Mar 2024). Cleared via 510(k) (Stelo via De Novo) - both are OTC wellness clearances.
• Claimed but NOT verified: Any AI comparable to Stelo's generative AI (not verified - adaptive/rule-based only); a named 'Lingo Coach' AI agent (does not exist); exact stale tier table ($49/$89 figures - verified entry is ~$54/2-week, time-sensitive); any generative-AI roadmap for Lingo (none announced, unlike Dexcom).
