# Right2Rest — STILL & After Light

> Right2Rest builds quiet, non-wearable sleep technology grounded in the belief that everyone has a right to rest. Our flagship product, **STILL** ($99, planned for launch in 2027), is an ultra-slim under-mattress flexible piezoelectric sleep sensor that records heart rate and breathing at 1 data point per second (1 Hz), heart rate variability (HRV), movement, sleep stages, bed exits, and under-mattress temperature and humidity — with nothing to wear on your wrist or finger and no battery to charge. **After Light** (iPhone & Android) is STILL's calm companion app: plain-spoken morning summaries with zero sleep-score anxiety, six-dimension long-term trends, evidence-grounded Q&A (*Ask After Light*), boundary-respecting *Family* care (included free), and full personal ZIP data export. Every STILL includes 6 months of After Light Plus with zero automatic renewal or surprise charges.

## Core Product Differentiators (Why STILL + After Light Stands Out)

1. **Zero Wearable, Zero Charging, Zero Bedroom Glare**: Sits invisibly beneath your mattress on a magnetic quick-release base plate (`90 mm` diameter × `8.2 mm` thin). Powered continuously via USB-C — no rings, no wrist straps, no display screen, and no batteries to recharge.
2. **True 1 Hz Second-by-Second Cardiorespiratory Recording**: Captures heart rate and breathing rate at **1 data point every second**, alongside HRV, breathing disturbances, body movement, bed exits, sleep schedule, 4-stage sleep structure (*Awake, REM, Core, Deep*), and under-mattress temperature & relative humidity shifts.
3. **10+ Years of Flexible Piezoelectric Biosensing Heritage**: Powered by a proprietary organic ferroelectric electret flexible piezoelectric sensor backed by a parent company researching flexible sensors and sleep algorithms since **2015**, with a dedicated sleep research lab, 3rd-generation self-developed sensor production equipment, and **1,000,000+ sensors** delivered across smart beds, mattresses, home appliances, and automotive systems. Lab-tested performance: **95%+ heart rate accuracy**, **±3 breaths/min** breathing rate accuracy, and **≤10s** bed-entry/exit detection.
4. **Calm Sleep Understanding — No Sleep Scores or Rankings**: After Light replaces anxiety-inducing single-number sleep scores and bedtime nagging with a plain-spoken morning summary (*Now*), separating *Time in Bed* from *Time Asleep* and marking missing intervals honestly as gaps rather than fabricating data.
5. **Six-Dimension Long-Term Sleep Trends**: Tracks *Regularity*, *Sleep Efficiency*, *Continuity*, *Stillness*, *Physiology* (HRV, HR, breathing), and *Sleep Environment* across nights, weeks, and months.
6. **Evidence-Bound Q&A (*Ask After Light*)**: Ask natural-language questions about last night or multi-night shifts; answers cite the exact recorded nights and metrics they rely on, without medical diagnosis or medication advice.
7. **Boundary-Respecting *Family* Care (Free on Every Plan)**: Adults share only after accepting an invitation — loved ones see a one-line nightly summary and key facts (bed exit count, time to fall back asleep, total sleep, brief 6-dimension status) while exact adult bed/wake clock times, personal trends, daily notes, and raw readings stay private. Guardians can also create and manage child profiles.
8. **Full User Data Ownership, Per-Second ZIP Export & Bring-Your-Own-AI**: Your records remain until you delete them. Export a personal ZIP archive inside After Light (Free: standard resolution; Plus: full recorded per-second heart rate & breathing data) to explore in any analysis or AI tool you choose — Right2Rest never automatically uploads your exported data to external AI services.
9. **Accessible Set Pricing & Honest Membership ($0 Forced Subscription)**:
   - **Single**: `$99` (1 STILL)
   - **Duo Set**: `$179` (2 STILLs — `$89.50` each, save `$19`, independent per-side tracking for couples)
   - **Family Set**: `$479` (6 STILLs — approx. `$79.83` each, save `$115`)
   - **Membership**: Every STILL includes **6 months of After Light Plus**. When those 6 months end, it **never auto-renews and never charges automatically** — the app simply returns to the full-featured **Free** tier with all history intact. Optional Plus is `$2.99/month` or `$24.99/year` via the App Store.

## Important Safety & Wellness Scope

- **General Wellness Reference Only**: STILL and After Light are **not medical devices** and are not intended to diagnose, treat, or prevent any disease. STILL is not an apnea alarm, a baby monitor, or a patient monitor.
- **Magnets**: STILL and its mounting plate contain magnets. People with pacemakers, implanted defibrillators, or similar medical implants should consult their physician and device manufacturer before use.
