The Next Frontier in Health Tracking

Sleep Index

The Sleep Index breaks your sleep down to what actually matters – how long you sleep, how well you recover, and how deeply your body resets. Track sleep duration, Resting Heart Rate (RHR), restfulness, and sleep stages including REM, Deep, and Light sleep to understand not just how much you slept, but how effectively.

Dynamic Recovery

Dynamic Recovery adapts to your body in real time, reading when you’re ready to perform and when recovery is non-negotiable. It goes beyond numbers by offering actionable recommendations, then recalibrates your recovery score as you implement them so you understand exactly when to push and when to rest.

Movement Index 

Movement Index is built to optimize for all day movement, not just workouts. By closely tracking steps, workouts, calories, and non-exercise activity, it helps improve glucose metabolism and increase all-day energy usage even when you’re outside your training routine.

Stress Rhythm

Stress Rhythm tracks how your heart responds over the course of the day, quietly analyzing HR, HRV, and RHR against the backdrop of your circadian rhythm. The result is a clear signal of your current state: stimulated, relaxed, or stressed – so you know when to lean in and when to step back.

UltraAge

Ultra Age is a science-backed aging marker powered by your physiology. It’s a single insight derived from your Brain Age, Pulse Age, and Blood Age as contributors. Track how lifestyle changes, sleep, exercise, and nutrition can impact your aging trajectory and turn insight into your competitive edge against time.

Women’s Health

Women’s health isn’t a single moment – it’s a journey that evolves across life stages, and the Ring PRO is built to support you through every one of them. It starts with the fundamentals: cycle tracking, prediction of ovulation, and logging symptoms so you can understand your body’s everyday rhythm. From there, it goes deeper – with confirmation of ovulation and unique patterns called Cycle Flags™ that surface insights most trackers miss, helping you take a more proactive approach whether you’re trying to conceive or simply tuning into your cycle. When pregnancy begins, pregnancy insights help you understand how your body is adapting week by week, from changes in resting heart rate and temperature to sleep and recovery. And as you move into perimenopause and menopause, the ring picks up on the subtle physiological shifts that define this transition – so you can navigate it with data and clarity, rather than guesswork. From your first cycle to midlife and every inflection point in between — this is health tracking built around the full complexity of being a woman. Unlock personalized health insights and proactively manage your reproductive health at every stage with Ring PRO.

PowerPlugs

PowerPlugs are precision micro-tools designed for highly personalized health insights, ensuring that you can tailor health tracking to your unique needs and goals. Supercharge and personalize your Ring PRO experience with a whole library of these micro-tools.

Caffeine Window: Time your caffeine for peak performance and protected sleep.
Caffeine isn’t just about how much – it’s about when. The Caffeine Window on the Ultrahuman Ring PRO uses your sleep and recovery data to map the exact times caffeine works for you, and when it starts working against you. Your window adapts daily. 

• Personalized Permissibility Window: A daily green zone when caffeine boosts focus and energy without disrupting sleep.
• Real-Time Body Caffeine: Log a drink and instantly see how much caffeine is still active in your system.
• Dynamic Cut-Off: Your evening cut-off shifts based on last night’s sleep quality and brain waste clearance.
• Caffeine Bonus & Detox Days: Great recovery earns you a later cut-off; poor recovery triggers a reset day to restore sensitivity.
• Frictionless Logging: A searchable drink library lets you log coffees, teas, and energy drinks in a tap.

Vitamin D: Optimize Vitamin D absorption by understanding your ideal sunlight exposure based on skin type and UV index.

Vitamin D from the sun depends on far more than just stepping outside – your skin type, location, and the current UV index all shape how much you actually absorb. The Vitamin D PowerPlug on the Ring PRO calculates the optimal time for you to head out, estimates the IU your skin will absorb during the session, and keeps you safely on the right side of overexposure.

• Personalized Sun Windows: Calculates the best times to step outside based on your skin type, location, and real-time UV index.
• IU Absorption Estimates: Tells you precisely how much Vitamin D your skin is taking in during each session – not just minutes spent outdoors.
• Real-Time Tracking: Monitors your exposure as it happens, so you know exactly where you stand.
• Safety Alerts: Flags overexposure before it becomes a sunburn risk, balancing benefit and skin health.

The result: healthy Vitamin D levels maintained the natural way – effortlessly, personally, and without the guesswork

Cardio Adaptability:  See how your heart handles stress, training, and recovery.
Your heart’s ability to adapt – to ramp up under exertion and settle smoothly into recovery – is one of the clearest signals of cardiovascular health. The Cardio Adaptability PowerPlug on the Ring PRO monitors your heart’s nightly activity using detailed tachograms and Lorenz plots, giving you a precise read on how your cardiovascular system is responding to exercise, stress, stimulants, and rest.

• Tachogram & Lorenz Plot Analysis: Visualizes beat-to-beat HRV patterns to assess how efficiently your heart shifts between exertion and recovery.
• Three-Tier Stress Classification: Categorizes nightly cardiovascular load as mild, medium, or high – so you can spot strain before it compounds.
• Lifestyle Signal Detection: Flags the impact of late workouts, caffeine, alcohol, poor sleep, and certain medications on your heart’s overnight recovery.
• Trend Tracking: Weekly, monthly, and yearly views reveal how your adaptability evolves with training, lifestyle changes, and age.

The result: smarter training decisions, better recovery, and a heart that’s resilient under load – with the data to back every adjustment you make.

Circardian Alignment: Sync your day with your body clock for better sleep, energy, and recovery.
Your body runs on a 24-hour internal clock that governs sleep, hormones, metabolism, and recovery. When your daily behaviors – light exposure, movement, meals – are out of sync with this rhythm, performance and sleep quality quietly suffer. The Circadian Phase Alignment PowerPlug on the Ring PRO maps your rhythm in real time and tells you exactly when to seek light, move, or wind down for maximum impact.

• Temperature Minima Tracking: Identifies your nightly core temperature low point – the reset button for your internal clock and the anchor for every other phase.
• Phase Advance Window: Highlights the morning window (~4 hours after your temperature minima) when light and movement shift your clock earlier, supporting earlier wake times and sharper morning alertness.
• Circadian Dead Zone: Flags the midday window when caffeine or exercise won’t disrupt your rhythm – ideal for stimulants and intense training.
• Phase Delay Window: Warns you when evening light or stimulants will push your clock later and suppress melatonin, so you can protect sleep onset.
• Dynamic, Personalized Windows: Your phases shift daily based on sleep timing, light exposure, exercise, travel, and nutrition – not generic clock times.
• Stress Rhythm Score Integration: Feeds into a circadian-aware stress score, so your stress data is read against your body clock, not in isolation.

The result: an internal clock that works with your lifestyle – better sleep consistency, sharper energy, smoother recovery, and an easier reset after travel or shift disruptions.

Respiratory Health: Understand how your nighttime breathing patterns shape your sleep quality.

Most respiratory disturbances – snoring, coughing, breathing disruptions – happen when you’re least aware of them. The Respiratory Health PowerPlug on the Ring PRO uses on-device audio to detect these events through the night and aligns them with your biometrics, so you can see exactly how your breathing is shaping your sleep, recovery, and long-term health. 

• Detect Respiratory Disturbances: Identifies snoring, coughing, and breathing disruptions overnight, with precise timestamps, duration, and intensity for each event.
• Patterns Over Time: One night tells you something; weeks reveal everything. Track how your respiratory health evolves and spot trends tied to seasons, habits, or specific days – before small issues compound.
• Whole-Body Context: Every event is aligned with your HRV, heart rate, movement, and sleep fragmentation – so you can see exactly when snoring spiked your heart rate or which disruptions actually impacted recovery.
• Morning Clarity: Wake up to an overnight summary of events, trends, and flagged changes – designed to help you make informed decisions, whether that’s a new sleep position, fewer late-night drinks, or a conversation with your doctor.
• Privacy by Design: Audio processing happens entirely on your phone. Nothing is recorded, stored, or uploaded.

The result: a clearer picture of your night-time breathing, the confidence that your data stays yours, and the early signals you need to protect long-term respiratory and cardiovascular health.

Cycle & Ovulation Pro: Clinical-grade cycle tracking, built into your ring.

Most cycle trackers predict – Cycle & Ovulation Pro confirms. Built directly into the Ring PRO and powered by OvuSense™ technology, it’s a regulated, medical-grade feature backed by 15 years of fertility science and trained on over 260,000 real-world cycles. Whether you’re trying to conceive, navigating an irregular cycle, or simply trying to understand your body better, you get clinical-level clarity – no extra device, no extra steps.

• Ovulation Confirmation (90%+ accuracy): Goes beyond fertile-window predictions to confirm whether ovulation actually occurred – the difference between guessing and knowing.
• Anovulatory Cycle Detection: Identifies cycles where ovulation didn’t happen, surfacing patterns most apps miss entirely.
• Built for Complex Cycles: Designed to deliver meaningful insights for users with PCOS, endometriosis, and irregular cycles . 
  
  The result: clinical-level cycle and ovulation insights, built into the device you already wear. 

Screen time: Track screen time and its impact on your sleep with personalized insights.
Screens aren’t the enemy – mistimed screens are. Blue light before bed delays melatonin; scrolling right after waking clouds focus. The Screen Time PowerPlug on the Ring PRO maps your screen use against your sleep and wake times, guiding you through four phases that protect deep work in the day and deep sleep at night.

• Morning Restriction: Limits screen use for one hour after waking for a sharper, calmer start.
• Tolerant Phase: A flexible mid-day window for free, balanced use.
• Wind Down Phase: Begins three hours before bed – your cue to dial down exposure.
• Restricted Window: The final hour before sleep, where screens are strongly discouraged to protect melatonin.
• Adaptive & Insightful: Phases recalibrate daily to your sleep, with prompts that tie screen habits directly to sleep outcomes.

The result: sharper mornings, deeper sleep, and a healthier relationship with your screens.

Social Jet Lag: Catch the circadian drift your weekend sleep-ins are causing.
You don’t need to cross time zones to get jetlagged. Inconsistent sleep timing between workdays and off-days creates a mismatch between your biological clock and your schedule – quietly impacting glucose, HRV, mood, and recovery. The Social Jetlag PowerPlug on the Ring PRO tracks this drift and helps you stay in rhythm.

• Mid-Sleep Point Tracking: Compares your sleep midpoint on workdays vs. off-days to detect drift you’d otherwise miss.
• Severity Flags: ≥60 minutes flags mild social jetlag; ≥90 minutes signals significant misalignment.
• Contextual Insights: Get notified when your weekly sleep timing meaningfully shifts – especially after weekends or travel.
• Pairs with Sleep Anchor: Use alongside Sleep Anchor for stronger rhythm stability.

The result: a steadier circadian rhythm, deeper recovery, and sharper daytime energy.

New Parent: Adapt your sleep, recovery, and movement scores to reflect the realities of new parenthood.

New parenthood doesn’t run on a 9-to-5 sleep schedule – and your scores shouldn’t punish you for that. The New Parent PowerPlug on the Ring PRO applies flexible thresholds, so quality rest at any hour is reflected fairly in your sleep and recovery markers.

• Flexible Sleep Timing: Recognizes broken, late, or off-hours sleep without penalty.
• Quality-Weighted Scoring: Prioritizes deep sleep, REM, efficiency, and restfulness over rigid duration rules.

The result: scores that support you through the chaos, with credit for the rest you do get.

Smart Alarm: Wake up gently during light sleep with science-backed tunes synced to your sleep cycles.

Traditional alarms don’t care what stage of sleep you’re in – they just go off. The Smart Alarm on the Ring PRO uses real-time sleep tracking to wake you during a lighter sleep stage within your chosen window, so you start the day refreshed instead of groggy. It’s not just an alarm – it’s a wake-up engine that aligns with your sleep quality, recovery, and circadian biology.

• Goal-Based Wake-Up: Wakes you when key sleep outcomes are met – Sleep Index goal, sleep debt repaid, sleep cycles optimally completed, or sleep duration target reached.
• Real-Time Stage Detection: Continuously analyzes your sleep stages and picks the lightest moment to wake you – minimizing grogginess and improving morning cognition.
• Customizable Gentle Window: Set a 15–60 minute range before your hard wake-up time, and the alarm finds the best moment within it. If your sleep goals aren’t met, it triggers 10 minutes before the hard limit – the final chance for an optimal wake.
• Hard Limit Safety Net: Your latest possible wake time always holds, so you’re never late – no matter what your sleep stage looks like.
• 3-Stage Progressive Alarm: Starts at 60% volume, ramps to 80% after 5 minutes, then 100% – easing you into wakefulness instead of shocking you out of it.

The result: smoother mornings, sharper energy, and an alarm that rewards good sleep habits instead of cutting through them.

Pocket Doctor : Connect with board-certified physicians – no waiting rooms, no scheduling hassles.

Insights are powerful – but sometimes you need a clinician. Pocket Doctor brings telehealth into the Ultrahuman app for US users, taking you from data to diagnosis to treatment without leaving the experience. The full clinical flow is handled by a certified telehealth partner – Ultrahuman doesn’t make clinical decisions.

• In-App Consultation: Chat directly with a licensed US physician.
• Prescription on Approval: Your physician can issue a prescription if clinically appropriate.
• Delivered to Your Door: Approved medications are fulfilled by a partner pharmacy.
• US-Only: Currently available exclusively in the United States.

The result: a seamless bridge from biomarkers to clinical care – a real physician, one tap away.

Ultrasync for Tesla:  Calculate your Drive Readiness Score and get a recommended driving mode based on your recovery.

Your sleep, recovery, and stress shape how you drive. UltraSync connects the Ring PRO with your Tesla, translating your health markers into real-time driving insights that help you manage stress, avoid fatigue, and drive safer. Health data stays private and is never shared with Tesla – everything is processed locally.

• Drive Readiness Score: A pre-drive rating based on sleep, recovery, and circadian rhythm, with a recommended driving mode to match. Scores below 40 flag as unsafe.
• Real-Time Stress Insights: Auto-detected journeys are mapped against your HR and HRV, showing exactly where your nervous system relaxed or spiked.
• Sick-Day Smart Cabin: When recovery dips or temperature rises, UltraSync adjusts fan speed and climate settings to ease airflow and reduce strain.

GLP-1: Track how your GLP-1 medication affects your HR, sleep, recovery, and metabolism.

GLP-1 has transformed weight loss – but without monitoring, it comes with real risks: muscle loss, metabolic slowdown, nutrient deficiencies. The GLP-1 PowerPlug on the Ring PRO combines medication access with continuous Ring data, Blood Vision biomarkers, and self-logged metrics – so every step of your journey is backed by real evidence.

• Ring Markers: Continuous tracking of sleep, HRV, RHR, and activity surfaces early signs of muscle loss or metabolic shifts.
• Weight & Muscle Mass Logging: Track trends across each dosage stage and catch lean mass decline before it compounds.
• Symptom Logging: Record side effects in real time to inform smarter dosage decisions with your doctor.

The result: weight loss that’s safer, more sustainable, and built on a complete picture of how your body is responding – not just a number on a scale.

BetterHelp: Connect with licensed mental health professionals for private, one-on-one support.

Mental health doesn’t always need a diagnosis – sometimes it just needs the right words at the right time. The BetterHelp PowerPlug on the Ring PRO surfaces daily, therapist-written articles from BetterHelp’s content library, building a quiet, judgment-free space to understand what you’re feeling, why, and what to do about it. 

• Therapist-Written Articles: Short, readable, non-diagnostic pieces covering emotional, cognitive, and psychological topics – curated from BetterHelp’s library.
• Personalized Topics: Choose 3+ areas so the content stays relevant to what you actually care about.
• Daily Reading Streaks: Build a steady reading habit – every article you read adds to your streak, encouraging consistent reflection.
• Saved Notes: Bookmark articles you want to revisit, building a personal library you can return to whenever you need it.

The result: a low-pressure, content-first mental wellness layer that builds awareness, validates common experiences, and gives you the space to work through things on your own terms.

Shift work: Adjust your baselines and metrics to match your work routines across weekdays and weekends.

Shift work doesn’t break your biology – fixed day-night assumptions do. Sleeping at 3 PM is just as valid as sleeping at 3 AM. The Shift Work PowerPlug on the Ring PRO recalibrates how your sleep is analyzed, so your insights stay accurate no matter when your day begins.

• Adaptive Tracking: Automatically recognizes your unique sleep-wake patterns – no manual input needed.
• Flexible Sleep Timing: Sleep is evaluated by quality, not clock time – no penalty for unconventional hours.
• Enhanced Nap Detection (V2): Trained on 1M+ naps, with real-time integration into Recovery Score and Sleep Debt.

The result: sleep insights built around your real life – better recovery, smarter wind-downs, full performance at any hour.

Pregnancy Mode: Gain insights into your health and baby’s development through pregnancy, with safety as the priority.

Pregnancy reshapes your physiology in ways generic trackers misread. A higher RHR in the first trimester isn’t a red flag – it’s your body building life. The Pregnancy Insights PowerPlug on the Ring PRO uses trimester-specific algorithms to read sleep, HR, HRV, temperature, and RHR through the right lens – so natural pregnancy responses aren’t penalized as poor scores. You also get timely nudges on hydration, gentle movement, and nutrition, matched to where you are in your journey.

The result: a supportive, informed view of pregnancy that adapts to your body’s evolving needs.
