Concept R&D

Health Ring.

Sleep + HR + SpO2. Prototype phase.

Sleep · HR · SpO2 · Skin temp · 7-day battery · 5ATM
Overview

What it is, and why I built it.

Health Ring is our R&D concept — a smart ring designed to compete with Oura, Ultrahuman, and Samsung Galaxy Ring.

We're not shipping this yet. We're testing prototypes with our internal team and select partners. This page shows what we're working on, why, and how it might fit your routine.

We're being honest about the timeline — getting health sensors right takes years of iteration. But the early results are promising.

Health Ring

Key features

Sleep Tracking
Sleep stages, HRV, respiratory rate. Comparable to Oura Ring Gen 3.
Continuous HR
24/7 heart rate monitoring with medical-grade accuracy.
SpO2 Sensor
Blood oxygen tracking for altitude, sleep apnea screening.
Skin Temperature
Trend tracking. Useful for cycle tracking, fever detection.
Activity Auto-Detect
Walking, running, cycling — auto-recognized.
7-Day Battery
Wireless charging case included.
Use cases

Where you'll actually use it.

Real scenarios from real users.

Sleep optimization
Track sleep stages, HRV. Wake at the right time in your cycle.
Endurance training
Continuous HR + HRV for training readiness.
Stress management
HRV trends show recovery vs. stress over time.
Health monitoring
Skin temperature trends detect fever before you feel sick.
Altitude acclimatization
SpO2 tracking for mountaineers, hikers.
Medical screening
Sleep apnea screening via SpO2 patterns. Discuss with your doctor.
Honest take

How Health Ring solves real problems.

Mapping the annoyances to the engineering.

The problem Health Ring solution
Oura Ring is expensive. We're targeting a more accessible price point.
Smart rings need daily charging. 7-day battery with wireless charging case.
I want medical-grade sensors. HR + SpO2 + skin temp, comparable to Oura.
Smart rings don't track sleep well. Multi-sensor fusion for sleep stage accuracy.
I want a ring that lasts. Titanium body + sapphire glass. IP68 + 5ATM.
Apps are confusing. Simple daily score + weekly trends. No data overload.

Smart Ring SR-2026 — what's inside
  • Gold-tone titanium band
  • Amber-resin inlay (signatures)
  • Heart-rate, SpO₂, sleep tracking
  • 7-day battery, magnetic charging
  • IP68 water resistance
My verdict

Health Ring.

I've worn an Oura Ring for 3 years. It's the only wearable I haven't taken off. Health Ring is our attempt to build something as good — at half the price.

We're currently in prototype phase. 5 team members have been wearing v1 prototypes for 4 months. Sleep tracking accuracy is within 5% of Oura. HR is within 2 BPM.
