Editorial summaries

Fitbit (Charge / Sense / Versa)

Fitbit (the Charge 6 band, plus the Sense 2 and Versa 4 watches; founded 2007 by James Park and Eric Friedman, acquired by Google in a deal that closed January 2021 for about $2.1B) is the budget-tier cleared anchor of the biometric cohort. The Charge 6, at about $160, brings cleared AFib/ECG (via electrodes on the Sense line), optical heart rate, SpO2, skin temperature, a Sleep Score and Sleep Profile, a Daily Readiness Score, and stress management, with an optional Fitbit Premium subscription (~$9.99/month). It is a Google product line, recorded in the registry as a distinct entity from the Pixel Watch and the Google company, and its health stack shares lineage with the Pixel Watch's Fitbit/Google Health algorithms. The throughline: the strongest cardiologist-validation gradient available at a budget price point, with the AI augmenting genuine biometric sensing.

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.
