# Happy Ring: robot model Canonical ID: `2af2d126-5e1a-4636-ac6f-cc5e0f8bbe1f` - **Slug:** happy-ring - **Form factor:** biometric - **Maturity stage:** commercial - **Lifecycle:** active - **Deployments registered:** 0 ## Specs - **notes:** [object Object],[object Object],[object Object],[object Object],[object Object],[object Object] - **specs:** Happy Ring: finger-worn smart ring. Sensors: 4 LEDs, 4 electrodes, 3-axis accelerometer, 2 temperature sensors -> heart rate, HRV, SpO2, skin temperature, respiratory rate, activity, sleep staging. Cleared sleep-apnea algorithm is the regulatory substance. Two FDA 510(k) clearances: K240236 (Oct 8 2024) = retrospective remote MONITORING of physiological parameters in adults at home or in healthcare facilities; K242224 (Jun 18 2025) = Home Sleep Test that processes ring signals for clinician-interpreted DIAGNOSIS of sleep disorders such as obstructive sleep apnea and insomnia, ages 22+, under direction of a trained healthcare provider. Company: Happy Health Inc (Austin TX); CEO Dustin Freckleton MD; $60M Series A (Aug 2022, ARCH Venture Partners), no later round surfaced. Distribution: sold ONLY bundled into the clinician-reviewed 'Happy Sleep' home-sleep-test service (insurer-billed), NOT a standalone retail ring; no published consumer price. - **formFactor:** biometric (biometric-primary smart ring; FDA-cleared sleep-apnea / sleep-disorder DIAGNOSIS support via clinician-reviewed home sleep test) ## Deployments _No deployments registered for this model._ ## Supply chain _No verified supply relationships on file. Supply-chain coverage is being added across the registry; check back as the seed populates this model's suppliers._ _Suppliers appear when verified with at least two strong sources. Sources are append-only; corrections add new sources rather than rewrite history._ ## Common questions ### What is Happy Ring? Happy Ring is a finger-worn smart ring made by Happy Health Inc of Austin, Texas, and it is recorded in the biometric form factor as the within-cohort genuinely-FDA-cleared sleep-apnea exemplar, the verified counterpoint to uncleared sleep-apnea claims elsewhere in the cohort. Its sensor stack of four LEDs, four electrodes, a three-axis accelerometer, and two temperature sensors yields heart rate, heart-rate variability, blood-oxygen saturation, skin temperature, respiratory rate, activity, and sleep staging, and the value of the device is its cleared sleep-apnea algorithm. It holds two FDA 510(k) clearances: K240236, decided October 8, 2024, for retrospective remote monitoring of physiological parameters in adults at home or in healthcare facilities, and K242224, decided June 18, 2025, a Home Sleep Test that processes ring signals for clinician-interpreted diagnosis of sleep disorders such as obstructive sleep apnea and insomnia in individuals aged twenty-two and older under the direction of a trained healthcare provider. The first clearance is best read as monitoring and the second as diagnosis-facilitating, so the genuinely-FDA-cleared framing holds while the diagnosis is clinician-mediated rather than autonomous, and the registry does not extend the claim beyond the cleared indication. Several cap-flags apply. The widely-cited figure of about ninety-seven percent agreement with gold-standard polysomnography is company-reported and has no peer-reviewed citation found, with the company's own technology page instead stating the softer claim of being ten times more accurate than a watch. Commercial availability is service-gated and thin: the ring is sold only bundled into the clinician-reviewed Happy Sleep home-sleep-test service, which is insurer-billed, rather than as a standalone retail ring with a published consumer price, and the company raised a sixty-million-dollar Series A in August 2022 led by ARCH Venture Partners with no later round surfaced, so it is an early-stage and quiet company; the maturity is recorded as commercial because the cleared service is live and billed, with the cap-flag preventing over-reading the FDA clearance as broad market presence. Finally, marketing references to brain activity or brain biometrics are flagged as marketing-forward because no EEG sensor is itemized on the spec page. The chief executive is Dustin Freckleton, MD. ### Who makes Happy Ring? Happy Ring is made by Happy Health, based in Austin, Texas, USA. ### Where is Happy Ring deployed? No verified deployments of Happy Ring are currently on the DEPLOY registry. DEPLOY records deployments only when verified at a named site with a primary source; absence may reflect pre-deployment, research, or manufacturer-internal use. ### What is Happy Ring's maturity stage? Happy Ring is at the commercial stage on the DEPLOY maturity ladder (research, prototype, pilot, commercial, production). Commercial stage means production-grade deployments are operating at named customer sites. ## Sources (7) 1. https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfPMN/pmn.cfm?ID=K242224 2. https://aasm.org/fda-clears-happy-ring-by-happy-health/ 3. https://www.biospace.com/press-releases/happy-ring-earns-second-fda-clearance 4. https://happysleep.com/tech 5. https://www.finsmes.com/2022/08/happy-health-raises-60m-in-series-a-funding.html 6. https://openloophealth.com/news/openloop-expands-into-sleep-diagnostis-with-happy-sleep 7. https://sleepreviewmag.com/sleep-diagnostics/home-testing/home-apnea-testing/happy-ring-maker-ensodata-offer-home-sleep-testing-solution/ _API: GET /v1/models/2af2d126-5e1a-4636-ac6f-cc5e0f8bbe1f ยท canonical URL: /models/happy-ring_
