Editorial summaries

Stelo

Dexcom's Stelo is the first-ever FDA-cleared over-the-counter (no-prescription) glucose biosensor (De Novo, March 5, 2024; US launch August 26, 2024): a 15-day continuous glucose monitor for adults 18+ not on insulin (type 2 not on insulin, plus non-diabetic users tracking how diet and exercise affect glucose). It is the generative-AI end of the glucose cell: Weekly Insights run on Google Cloud's Vertex AI and Gemini, with AI photo meal-logging and personalized daily recommendations, the AI substance that carries it across the biometric boundary. Pricing is about $89 for a 2-week sensor on a biweekly subscription model (around $99/month). From DexCom (NASDAQ: DXCM), Stelo is the OTC product line, separate from the prescription G7. Cap-flag: the cleared indication is an OTC CGM for adults 18+ not on insulin; it is explicitly NOT cleared for problematic hypoglycemia and has no low-glucose alerts, so it should not be read as a diabetes-management device.

Ultrahuman Ring (Air / Pro)

The Ultrahuman Ring (the Ring Air, plus the Ring Pro that brought a global roughly $349-to-$399 launch around February 2026 with 15-day battery; from Ultrahuman, founded 2019 in Bengaluru by CEO Mohit Kumar and co-founder Vatsal Singhal, with a Plano, Texas factory) is the market-access-redesigned archetype of the ring sub-cohort. Its AI comes via modular 'PowerPlugs' (metabolic and cardio adaptability, circadian rhythm, caffeine window, AFib, cycle), with no mandatory subscription for core tracking and some premium PowerPlugs paid (AFib at about $4.90/month); AFib detection runs through the third-party FibriCheck app, not a native FDA clearance. The within-entity verified-vs-claimed exemplar is market access, not the product: US market access was blocked on October 21, 2025 under Oura's ITC patent ruling (US Patent 11,868,178), then restored on March 24, 2026 when the Ring Pro's unibody redesign cleared US Customs, a company-availability story that parallels the Apple Watch's disabled-then-restored blood-oxygen feature. The product and AI existed globally throughout; only US market access was interrupted. Price is about $349 (Air) to $399 (Pro), subscription-augmented.
