Editorial summaries
Samsung Galaxy Ring
The Samsung Galaxy Ring is available for purchase directly from Samsung's website with a Buy Now button; a sizing kit is offered for customers who do not know their ring size. The Samsung Galaxy Ring is priced from $299.99 USD before trade-in, with up to $150 instant trade-in credit available; financing is offered through Affirm at 0 to 36 percent APR.
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.
