Sleepal is a smart bedside lamp powered by AI that does two main things simultaneously: it tracks your sleep quality using radar and multi-sensor technology, and it creates an optimised sleep environment through adaptive lighting, sound, and guided routines. Think of it as a sleep coach, a premium lamp, and a clinical-grade biometric monitor combined into a single nightstand device.

Anyone who wants to sleep better — especially people who find wearable trackers uncomfortable, people who struggle to fall or stay asleep, busy workers and students, parents, seniors, and anyone who wants to understand why their sleep quality varies night to night without needing to wear any hardware to bed.

A regular smart lamp lets you control brightness and colour remotely. Sleepal is purpose-built around sleep science — every feature, from the Ra95+ lighting spectrum to the patented alarm system, is designed around what your body actually needs to fall asleep faster, stay asleep longer, and wake up feeling rested.

Most trackers measure sleep passively and give you a report in the morning. Sleepal goes further in three ways:

• It tracks more data types — breathing, sleep position, snoring patterns, and room environment — not just heart rate and movement.
• It requires nothing on your body, unlike rings, watches, or chest straps.
• It actively helps you sleep better in real time through adaptive lighting, sound, and smart routines — not just after the fact.

No. Sleepal is a consumer wellness and lifestyle product. It does not diagnose or treat any medical condition. If you have a clinically diagnosed sleep disorder like severe sleep apnea, consult a doctor. Sleepal's data can be a genuinely useful conversation starter with a healthcare provider, but it is not a medical-grade diagnostic tool.

It can replace your wearable specifically for sleep tracking — which is where Sleepal is most accurate. For daytime activity tracking (steps, workouts, GPS), your watch still plays a role. Sleepal connects with Apple Health and Google Fit to combine daytime and nighttime data for more complete insights.

No subscription is required for core features. All sleep analytics, historical data, smart alarm, adaptive lighting, and environmental monitoring are included in the $399 purchase price permanently. An optional "AI Coaching" premium tier may be offered in the future, but as of January 2026, all primary features are free with no ongoing cost.

Because Sleepal tracks biometric markers associated with sleep health — respiratory rate, heart rate, sleep staging, and snoring patterns — many US FSA and HSA administrators classify it as an eligible wellness device. Eligibility varies by plan and administrator, so confirm with your specific FSA/HSA provider before purchasing with those funds.

Very accurate for a consumer home device. Validated against PSG — the gold-standard hospital sleep test:

• Heart rate: 95% accuracy compared to hospital-grade ECG monitors.
• Breathing rate: RMSE of 0.41 compared to professional respiratory belts — essentially clinical-grade performance.
• Sleep stage detection: 78–89% agreement with PSG — rated "strong agreement" by sleep scientists.

The dataset behind these figures spans over 2,000 PSG-validated nights, not a handful of lab sessions.

In my direct 14-night conflict test wearing both simultaneously:

• Resting heart rate: matched within 1–2% — essentially identical.
• Sleep stage classification: Sleepal ~89%, Apple Watch ~82% against PSG reference.
• Respiratory rate: Sleepal RMSE < 2.0, Apple Watch ~RMSE 2.8. The gap here is significant — radar measuring micro-chest-movement is a more direct method than optical sensors inferring breathing from blood flow patterns.

For pure sleep tracking accuracy, Sleepal wins. For everything else you do with an Apple Watch during the day, the watch still has its place.

A confusion matrix is a grid that compares Sleepal's predicted sleep stage against what a professional sleep lab actually recorded at the same moment. High numbers along the diagonal mean Sleepal frequently gets it right. Low numbers off-diagonal mean it rarely confuses one stage for another.

In plain terms: it's Sleepal's transparent report card. The scores are strong for both healthy sleepers and people with more complex sleep patterns — and Sleepal publishes this data openly rather than hiding behind vague accuracy claims.

Sleepal has been separately tested with people who have obstructive sleep apnea (OSA) — a condition where breathing repeatedly stops and starts during sleep. Separate accuracy results are published for this population, reflecting the more complex, interrupted sleep patterns involved. The data is transparent and available for review. Sleepal does not claim perfect accuracy for clinical populations, but performance remains meaningful for home-use monitoring.

Yes. mmWave signals at 60GHz pass through fabric, cotton, foam, and standard bedding materials without significant signal loss. I specifically tested this with a 15lb weighted blanket — accuracy degraded by less than 4% compared to a standard duvet. The materials that cause real problems are dense metals (like a thick metal bed frame directly between the lamp and your torso), not fabrics.

The AI is trained to prioritise and isolate the person closest to the lamp, so one person can use it reliably in a shared bed. For individual clinical-grade data on both partners simultaneously, Sleepal recommends two units — one on each nightstand. The 60GHz signals from two lamps operating simultaneously do not interfere with each other, and each builds its own independent sleep profile.

• 🌈 Adaptive Ra95+ Lighting — circadian-tuned warm light that dims toward bedtime and brightens at wake-up with a sunrise simulation.
• 🎵 Calming Soundscapes — white noise, nature sounds, ambient music to mask disruptive noise and ease the mind.
• 🫁 Guided Breathing Sessions — audio and light-cued breathing exercises to lower heart rate and cortisol before sleep.
• 🤖 Personal AI Sleep Coach — actionable, personalised tips based on your actual multi-night data trends.
• ⏰ Stand-to-Stop Smart Alarm — only deactivates when you physically stand up from the bed.
• 🌡️ Environmental Monitoring — tracks room temperature, humidity, noise levels, and ambient light to explain sleep quality variations.
• 📍 Sleep Position & Snoring Tracking — correlates body position with snoring episodes to make the data actionable.
• 🏠 Smart Home Integration — works with Apple Home, Google Home, and Amazon Alexa.

Yes. The AI builds a personal sleep profile from your nightly data and adjusts recommendations accordingly. The longer you use it, the more accurate and personalised the insights and automatic routines become — the first week gives you a baseline, but the real value compounds over months.

Complete control through the app: brightness level, colour temperature (warm amber to cool daylight), specific colour, sound type, and volume. You can set fixed preferences or allow the AI to adjust automatically based on your biometric signals. Whether you want warm amber silence or nature sounds at 40% volume — it's fully configurable.

Yes — and it's genuinely excellent for it. Ra95+ colour rendering means text on a printed page looks crisp and natural. The full-spectrum output eliminates the blue-heavy tint common in most LED reading lamps, reducing eye strain during longer sessions. You get a premium reading lamp and a sleep tracker in the same device.

• 📻 White noise — a steady, consistent background hum that masks variable environmental sounds
• 🌿 Nature sounds — rain, ocean waves, forest ambience, birdsong
• 🎶 Calming ambient music — low-stimulation instrumental tracks

Future updates plan to add guided sleep meditations and breathing exercises from certified sleep coaches.

Yes. Set a wind-down time in the app and Sleepal automatically begins dimming lights, shifting colour temperature toward warm amber, starting your chosen sounds, and guiding your breathing — all without you touching anything. You can create fixed daily schedules or let the AI adapt timing based on your natural rhythm patterns.

Yes. The acoustic sensor detects and logs snoring events, then the AI correlates them with your sleeping position data from the thermal array. Over multiple nights, the app builds a pattern — for example, "snoring occurs 73% more often when you're on your back between 2–4am." This makes the data actually actionable, not just a notification that you snored.

Yes. Sleepal syncs with both Apple Health and Google Fit, pulling in your daytime activity, exercise, and step data to give the AI more context. Understanding whether you exercised that day, your activity level, and your overall health patterns makes the sleep coaching recommendations more accurate and personalised.

Sleepal addresses the three biggest obstacles to winding down: light, sound, and stress. Warm, low-blue light tells your brain it's nighttime and stops suppressing melatonin. Soothing sounds give racing thoughts an anchor point outside your own head. Guided breathing exercises activate your parasympathetic nervous system — the body's "rest and digest" mode — which physically lowers heart rate and cortisol. All three working together make transitioning into sleep noticeably easier.

Photoreceptors in your eyes called intrinsically photosensitive retinal ganglion cells (ipRGCs) are specifically sensitive to blue-wavelength light at 400–490nm — peaking around 450nm, exactly where phones and white LED bulbs emit most intensely. When stimulated, these receptors send a signal to your brain's circadian clock that suppresses melatonin production and increases alertness. Sleepal's evening RG0 Zero-Blue Light mode produces light predominantly above 500nm (warm amber range), so your melatonin rises naturally as bedtime approaches rather than being chemically delayed.

Slow, controlled breathing activates the vagus nerve and the parasympathetic nervous system, measurably slowing heart rate, lowering blood pressure, and reducing cortisol. Research consistently shows that 4–7 minutes of paced breathing before bed reduces sleep onset time and increases deep sleep duration. Sleepal's sessions use light cues and audio tones to guide your breath rhythm without you needing to count consciously — you just follow the light.

One of Sleepal's most underrated benefits. When you have an appealing alternative — warm light, good sounds, a breathing session — putting the phone down is genuinely easier because you're replacing a stimulating habit with a calming one, not just removing something. The melatonin you stop suppressing is a real physiological payoff you'll feel within a week.

Yes. You can trigger the wind-down routine manually at any time — it's not locked to a fixed clock. The AI also accounts for schedule variability when building your long-term sleep profile, so irregular bedtimes don't corrupt your data or recommendations. It adapts to you rather than requiring you to adapt to it.

Yes. Recreating your familiar pre-sleep environment in a hotel room — the same light warmth, the same sounds, the same wind-down sequence — helps your circadian system recognise that it's time to sleep regardless of the local time zone. Sleepal is portable and plugs into any standard outlet, so you can take the routine with you.

Yes for all three groups. For children and teens, the gentle lighting and routine structure are especially effective — younger circadian systems are more sensitive to light timing, and the "Natural Sleep Optimisation" mode adjusts for developing sleep patterns. For seniors, the camera-free, wearable-free monitoring provides families a way to check sleep quality remotely through the app while respecting privacy and independence. No camera, no wearable, no intrusion.

Once your routine starts, Sleepal runs completely autonomously. It dims and shifts light colour on its own schedule, transitions sound to your chosen sleep audio, and — if connected to smart home devices — can trigger thermostat adjustments, turn off other connected lights, and even signal a smart plug to cut power to a TV. You lie down. It handles everything else, including turning the light fully off once it detects you're asleep.

Covered under patent CN202510390595.4A, Stand-to-Stop uses the lamp's presence detection to monitor whether you remain horizontal in bed. The alarm begins as a gentle, gradually increasing tone. It will not fully deactivate until the radar registers that you have physically stood up from a lying position. A single "Turn-to-Snooze" gesture grants one brief grace period. After that, vertical is the only exit. In 14 nights of SC Lab testing, the tester did not once fall back asleep after the alarm sequence started.

A natural rolling-over movement in bed that the thermal and radar sensors recognise as a deliberate snooze request — without you fumbling for a button or touching the lamp. You get one snooze per alarm cycle. After the snooze window closes, Stand-to-Stop resumes and requires you to actually get up to silence it completely.

Yes — that's what the Smart Alarm does. It monitors your sleep cycle in real time and triggers the alarm when you're in your lightest sleep stage within a 30-minute window before your set wake-up time. Waking from light sleep versus deep sleep makes a dramatic difference to how alert and rested you feel immediately after getting up.

Starting 20–30 minutes before your alarm time, the lamp slowly increases from near-darkness to full natural daylight brightness, simultaneously shifting colour temperature from warm amber toward cool daylight white. This mimics the gradual light increase of an actual sunrise, prompting your body to begin producing cortisol naturally — so by the time the audio alarm sounds, you're already transitioning out of sleep rather than being ripped out of it cold.

You need it for initial setup and to customise your routines and preferences. After that, Sleepal runs saved routines independently without the app being open or your phone nearby. The app is where you review your sleep data, receive AI coaching insights, and make changes to your configuration.

100% free to download and use. All core analytics, sleep history, smart alarm, adaptive lighting, and coaching features are included at no additional cost — no subscription tier required for the primary feature set.

Yes — as long as the lamp is connected to your home Wi-Fi, you can adjust settings, start or stop routines, and monitor data from anywhere via the app. Useful for parents setting up and adjusting routines in children's rooms remotely.

Yes, regular firmware and app updates improve performance, fix issues, and add new features. The AI models improve over time as more data is collected across the user base. During a firmware update (which takes a few minutes), some lamp features may be temporarily unavailable.

Currently English, German, Spanish, and French. Additional languages are planned in future updates.

Not currently — each lamp pairs with one phone account at a time. Multi-account support for shared households is being considered for a future update.

Nothing disruptive. Sleepal continues running your saved routines independently. Overnight tracking data is stored on the device and syncs to the app automatically when the connection is restored in the morning.

No — absolutely no camera. Sleepal uses anonymous radar waves and heat gradient patterns (thermal array). There is zero video or photo recording capability. The thermal sensor creates temperature maps, not images — it cannot produce anything resembling a photograph or video frame.

The Privacy Button is a physical hardware switch that cuts the electrical circuit to the microphone and thermal sensors. This is fundamentally different from a software setting — a software toggle could theoretically be overridden by a firmware update, a bug, or a remote access vulnerability. A physical circuit disconnect cannot. When the Privacy Button is engaged, those sensors are electrically dead regardless of what any software instructs. For a device in your bedroom, this architectural choice matters.

Only with your explicit permission, and only for short snoring detection clips. These recordings are stored within your private app account only — no audio is transmitted to external servers for analysis, and no one else can access these clips. The physical Privacy Button can cut mic power entirely if you prefer zero audio collection.

The raw radar waveforms — the most sensitive biometric data — are processed entirely on-device and never uploaded. What optionally syncs to the cloud (with your permission) is already-abstracted data: your sleep stage timeline, breathing rate number, heart rate average, and environmental readings. Sensors used:

• 60GHz radar: chest movement for breathing and heart rate (processed on-device only)
• Thermal array: anonymous heat gradients of the bed surface for position detection
• Acoustic sensor: ambient noise level and snoring detection
• Environment: room temperature, humidity, and light level

Only you. Data lives on encrypted protected servers, is used only to generate your personal insights, and is never sold or shared with third parties. Even Sleepal's own team cannot access individual user data — it's a closed, private system. Only your personal account login provides access.

Yes — full deletion is available directly within the app at any time, no waiting period, no support ticket required. You have complete control over your information.

Optional but recommended. With an account: personalised AI coaching, cloud backup of routines and history, and remote control from anywhere. Without an account: the lamp works in basic mode with local-only routines and no data backup.

Yes — encrypted cloud backup means your full sleep history, settings, and personalised routines restore automatically when you log into the app on a new device. Nothing is lost when you upgrade your phone.

Most modern iOS and Android smartphones with Bluetooth and Wi-Fi capability. The Sleepal app is available on both the App Store (iPhone) and Google Play (Android).

Both serve different purposes: Bluetooth is used for initial pairing and nearby direct control. Wi-Fi enables remote access from anywhere, cloud data sync, and firmware updates. Once routines are configured, core sleep tracking and alarm functions work without an active Bluetooth connection — the lamp operates independently.

Yes. Compatible with Amazon Alexa, Google Home, and Apple Home. This allows Sleepal's bedtime routine to trigger coordinated changes across other smart devices in your bedroom — thermostat adjustments, other lights dimming, smart plugs cutting power to TVs, and more.

Yes — unplug, move, plug back in, reconnect to Wi-Fi if the network differs. All your routines and preferences are stored in your account, not the physical device location, so everything transfers instantly.

No. Once configured, Sleepal runs completely independently overnight. Your phone can be in another room, powered off, or in aeroplane mode — the lamp will complete its routines, track your sleep, and fire the alarm exactly as scheduled.

Reconnect through the app's network settings — takes about a minute. All saved routines, preferences, and historical data are preserved through your account, unaffected by the network change.

On your nightstand, positioned so the lamp has a reasonably clear line of sight toward your torso area — within approximately 1.5 metres. Avoid placing it behind dense metal objects, thick solid headboards, or large wooden furniture. The radar passes through fabric and bedding without issue; it's primarily dense metal structures that degrade signal quality noticeably.

Yes — completely safe for daily long-term use. The 60GHz radar operates at power levels comparable to a standard home Wi-Fi router, well within all international non-ionising radiation safety limits. The technology is non-ionising, meaning it does not damage DNA or biological tissue. Devices using this frequency range are found in automotive sensors, motion detectors, and consumer electronics routinely.

No. Built-in thermal management circuitry and automatic safety shutoffs prevent overheating under normal operating conditions. The device is specifically designed and tested for continuous overnight use and runs cool to the touch.

Yes. The RG0 Zero-Blue Light certification confirms the lamp produces no meaningful blue-light output in sleep mode — the safest possible classification. Full-spectrum Ra95+ output in reading mode also produces no harmful glare. Both modes are gentle on developing and adult eyes alike.

No. Sleepal is designed and certified to meet global electromagnetic compatibility (EMC) standards. It will not interfere with phones, Wi-Fi routers, televisions, hearing aids, or any other household electronics.

Yes. No sharp edges, no hot external surfaces, no harmful emissions at household power levels. Safe for homes with children and animals.

No. No replaceable parts, no filters, no physical maintenance required. Software and firmware updates are delivered automatically. Hardware defects are covered under the manufacturer warranty.

Yes. Designed and tested to meet international electrical product safety standards. All electrical components are certified for household use in applicable markets.
