From Apple Watch to Smart Rings: Where Biometric Wearables Are Really Headed

When the Apple Watch arrived, it helped turn heart‑rate and activity tracking into something mainstream. A decade later, we’re no longer talking about just “a watch on your wrist,” but about an entire layer of biometric wearables – from watches to rings – capturing continuous data about our bodies and behavior.


Recent market research put the global smartwatch segment close to 90–100 billion USD in 2025, with projections that it could more than triple to over 300 billion USD by 2034, growing at roughly 14–15% per year. Apple’s wearables business alone has been estimated at close to 40 billion USD in annual revenue, which shows how central the Apple Watch has become to this category.


Smart rings are still a much smaller slice of the market, but they’re catching up fast. Some studies estimate the smart ring segment to evolve from under 10 million USD in 2023, to reaching tens of millions by 2030 and scenarios that point to multi‑billion‑dollar value longer term, with CAGRs above 25–30% as more brands enter the space. Health and wellness tracking – sleep, heart‑rate variability, stress – is the primary growth engine here.


What’s interesting is how quickly smart rings are moving from “silent trackers” to conversational interfaces. Luna’s latest update turns its ring into what some reports call the first smart ring you can really talk to: users can log meals, caffeine, workouts and subjective well‑being by voice, and ask questions about sleep, recovery, stress or performance, with responses grounded in their live biometric data. The ring focuses on sensing while the phone handles voice input and AI, making the experience more about natural interaction than dashboards and manual logging.


If we zoom out to wearable biometric monitors more broadly – devices that track vital signs continuously for wellness or clinical use – recent reports value this segment at 25–26 billion USD by 2034, at about 9% CAGR. North America currently leads, but Asia‑Pacific is expected to be the fastest‑growing region as smartphone penetration and digital health initiatives expand.


audioXpress has been following this evolution not only from a “health gadget” angle, but also from an audio and UX perspective: how biometric sensing, low‑power processing and voice interfaces are converging in devices like the Apple Watch and in emerging form factors such as smart rings and hearables. The discussion goes beyond counting steps – it touches on how biometric and acoustic signals can shape personalization, safety and ambient intelligence in everyday devices.


Put together, the numbers and the technology trend seem to be pointing in the same direction: biometric wearables are moving from single‑purpose trackers to multi‑sensor, multimodal companions. Smartwatches like Apple Watch and next‑generation rings such as Luna’s may soon feel less like “gadgets” and more like quiet infrastructure for health, identity and interaction.


For product, customer experience, and business leaders, the key question is how fast biometric wearables will move from “interesting gadgets” to core data inputs for services, personalization, and risk decisions. Are you already building strategies that assume watches and rings will be part of your customer data stack, or are you still treating them as a side trend?
