Every product here has been evaluated against the sleep science, not the marketing copy. We flag what works, what doesn't, and who it's actually for.
Ultrahuman Ring AIR
Lightweight continuous sleep + metabolic tracking
The lightest sleep ring on the market with no subscription fee. Tracks HRV, skin temperature, sleep stages, and recovery score. The metabolic panel makes it a standout for data-driven professionals who want sleep and performance data in one device.
Ultrahuman Ring PRO
Advanced metrics with real-time glucose integration
Step up from the AIR with deeper biometric logging, priority data processing, and compatibility with Ultrahuman's CGM platform for glucose-linked sleep correlation. Designed for optimizers who want the full picture, not just sleep scores.
Ultrahuman Home
Ambient bedroom environment tracking — no wearable required
A bedside monitor that tracks sleep-critical environmental variables — temperature, light, air quality, noise — and maps them against your sleep data. Ideal for anyone who wants to understand how their bedroom setup is affecting their recovery without wearing a device.
All three devices. One decision. Here's what separates them.

HRV Tracker & Recovery Log
30-day wearable data tracker with trend analysis
A pre-built Google Sheets template that turns your daily wearable readings into trend lines, weekly averages, and recovery scores. Tracks HRV, resting HR, deep sleep, REM, SpO2, and total sleep across 30 days — and surfaces the patterns most people miss when reading single-night data.
The Sleep Reset
Structured 30-day sleep habit reset protocol
A 30-day program designed to rebuild disrupted sleep architecture from scratch. Works through a progressive daily protocol that gradually re-trains the body's natural sleep-wake rhythm. Well-suited for shift workers, frequent travelers, or anyone coming off a prolonged period of poor sleep.
4GreatSleep
Holistic sleep optimization system for deep recovery
A comprehensive approach to sleep quality combining behavioral techniques, environmental adjustments, and supplementation protocols. The program is structured around four evidence-based pillars and includes a wearable-friendly tracking framework to measure your progress.
Stop Snoring & Sleep Apnea Program
Natural airway and throat exercise protocol
A clinically informed exercise-based program targeting the root muscular cause of snoring and mild-to-moderate sleep apnea. Focuses on throat and airway conditioning through daily movements. Notable for addressing SpO2 issues that wearable data often flags before a formal diagnosis.
The SleepMetric Protocol
Complete 7-module sleep optimisation course
A complete sleep optimisation system built around your wearable data. Seven structured modules covering sleep architecture, environment engineering, circadian timing, supplementation, and stress-recovery balance — with a 30-day progressive implementation plan and lifetime access via ThriveCart Learn.
The 7-Night Sleep Reset
Week-long protocol to rebuild your sleep baseline
A structured 7-night protocol that addresses the four highest-impact sleep variables in a specific sequence — environment first, then timing, then supplementation. Designed for people who want a clear, no-guesswork starting point with night-by-night instructions and wearable metric targets for each night.
