Overview
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.

- How much does Happy Ring cost?
- Happy Ring's price is not publicly disclosed. DEPLOY has no verified price on record for Happy Ring from Happy Health. Physical-AI systems like this are often sold through enterprise contracts or operated as a service rather than at a public list price; check the manufacturer for the latest.
- Is Happy Ring actually deployed in the real world?
- Happy Ring is recorded at the commercial stage, but DEPLOY has no deployment verified at a named site yet; vendor deployment claims are not independently confirmed here. Manufacturer capability claims should be read as claims pending independent verification.
- Who makes Happy Ring?
- Happy Ring is made by Happy Health, based in Austin, Texas, USA.
- Can you buy Happy Ring?
- Happy Ring is in commercial deployment and is sold to operators; contact the manufacturer to buy, and see the pricing section for any recorded price.
- What are alternatives to Happy Ring?
- On the DEPLOY registry, comparable biometric robots to Happy Ring include Butterfly iQ+, Apple Watch, Butterfly AI Ultrasound, Evie Ring (and EvieMED).
- How does Happy Ring compare to Butterfly iQ+?
- Happy Ring and Butterfly iQ+ (Butterfly Network · 2 deployments) are both biometric robots on the DEPLOY registry. Happy Ring has 0 verified deployments on record. Compare both records for specs, safety, deployments, and verified-vs-claimed autonomy.
- Is Happy Ring a top biometric?
- On DEPLOY's intelligence score, which blends verified deployments, safety, adoption, media, and IP signals, Happy Ring ranks in roughly the top 100% of biometric models tracked by the registry.
- 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.
- 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.
- Is Happy Ring safe?
- Happy Ring has no incidents on record in the DEPLOY registry. This does not constitute a safety guarantee; it reflects the incidents DEPLOY has tracked and verified to date.
