Editorial summaries

RingConn (Gen 2 / Gen 3)

RingConn (the Gen 2 at about $279, plus the Gen 2 Air and a Gen 3 arriving late May 2026; from RingConn, Shenzhen) is the subscription-free archetype of the biometric ring sub-cohort: all standard features are free for life, the core positioning against Oura's required membership and Whoop's subscription-only model. Its sensors (PPG, skin temperature, SpO2, accelerometer) drive sleep, heart rate and HRV, and a deep-learning sleep-apnea / AHI screening feature, with 10-to-12-day battery (the charging case extends to about 150 days). The verified-vs-claimed throughline: the sleep-apnea / AHI feature is a company-claimed screening capability (RingConn cites about 90.7% accuracy) that is NOT FDA-cleared. RingConn's own materials say it is 'actively pursuing clearance' and 'not intended to diagnose'; DEPLOY records the AHI claim as claimed, not cleared, the direct counterpoint to the genuinely-cleared Happy Ring in the same form factor. On the patent front, RingConn settled and licensed cleanly in the smart-ring ITC litigation; it was not import-banned, unlike Ultrahuman. Price is $279, subscription-free.

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.

Common questions

What is the difference between RingConn (Gen 2 / Gen 3) and Stelo?
RingConn (Gen 2 / Gen 3) and Stelo are both biometric robots on the DEPLOY registry. They differ in maker, maturity, price, verified deployments, and how much of their autonomy is independently verified. See the table above for the full head-to-head; each figure is sourced.
Which is cheaper, RingConn (Gen 2 / Gen 3) or Stelo?
Stelo has the lower recorded price on the DEPLOY registry than RingConn (Gen 2 / Gen 3). Prices are sourced; see each record for whether the figure is a manufacturer target, an estimate, or an actual sale price.
Is RingConn (Gen 2 / Gen 3) or Stelo more autonomous?
On the DEPLOY registry, neither RingConn (Gen 2 / Gen 3) nor Stelo has capabilities independently verified as fully autonomous yet; their recorded capabilities are teleoperated-assisted, demonstrated, or vendor-claimed. See the table for each capability's verification status.
Which has more verified deployments, RingConn (Gen 2 / Gen 3) or Stelo?
Stelo has more verified deployments (1) on the DEPLOY registry than RingConn (Gen 2 / Gen 3) (0). DEPLOY counts a deployment only when confirmed at a named site with a primary source.
