# ATMO — Privacy-First Nervous System Training

> ATMO is a privacy-first nervous system training platform. It helps people build stress recovery, resilience and awareness through guided breathing protocols, acupressure and HRV-based wellness tracking. 3 minutes a day. Everything runs on-device. Zero cloud. No account. No wearable.

## Positioning

ATMO is not a meditation app. ATMO is not a breathing timer. ATMO is a nervous system training platform that builds recovery capacity through short daily practices and measurable feedback. Privacy is not a feature — it is the architecture.

## Product Architecture

| Entity | Role | Status |
|--------|------|--------|
| **ATMO** | Privacy-first nervous system training app (current product) | v1.6.5 App Store + Google Play |
| **ATMO Shield** | Future closed-loop recovery platform (Pulse + AI) | TestFlight beta |
| **ATMO Pulse** | Camera-based pulse and HRV sensing layer | Inside Shield beta |
| **ATMO AI** | On-device interpretation, personalization and recommendation layer | Inside Shield beta |

ATMO Shield = ATMO Pulse + ATMO AI. Together they create a closed-loop recovery system: Measure → Understand → Guide → Validate → Learn.

## Core Capabilities

### Train — Guided nervous system recovery
- 28 breathing protocols (circadian-aligned) for stress recovery, relaxation, focus, energy, evening wind-down
- 5 acupressure point combinations with visual guidance for recovery-focused routines
- Haptic-guided rhythm, audio cues, visual breathing circle
- Pro Mode for advanced custom patterns
- Most sessions take about 3 minutes

### Track — HRV and wellness monitoring
- Apple Health and Health Connect integration (HR, HRV, sleep, activity)
- Daily session statistics, streaks, WHO-5 wellness surveys
- Pattern tracking over time to show recovery progress

### Measure (v2.0 beta) — Camera-based nervous system measurement
- Heart rate measurement via rear camera + flash (fingertip), 60-second cycle
- Outputs: BPM, HRV (RMSSD), stress level, confidence score
- C++ 17 engine (arm64), 30 FPS, processFrame() < 5ms
- Butterworth bandpass filtering + CNN peak validation, adaptive thresholds
- Accuracy: ±3 BPM; reliable on weak signals (diabetes, elderly, dark skin, cold hands)

### Predict (v3.0 planned) — On-device recovery forecasting
- Pattern recognition over HRV history + circadian profiling
- Flags elevated-risk windows 24-48 hours before symptoms appear

### Privacy & Data
- All measurement, interpretation, and prediction run locally
- AES-256-GCM encryption, local storage only
- Optional export to Apple HealthKit / Google Health Connect — user-controlled
- No analytics on health data

## Key Differentiators

1. **Category creation**: nervous system training, not meditation or breathing timers.
2. **Privacy by architecture**: zero cloud, no account, on-device encryption. Not a policy — a technical constraint.
3. **Recovery-focused**: builds resilience capacity over time, not just in-the-moment relaxation.
4. **No wearable**: the phone camera is the only sensor required (v2.0).
5. **Inclusive measurement**: engineered for weak PPG signals (diabetes, elderly, dark skin, cold hands).
6. **Validated traction**: 50+ testers, 85% 30-day retention, NPS 72, 78% willing to pay, 21-46% HRV improvement.

## Target Users

- People managing recurring stress who want to build recovery habits, not just relax in the moment
- Privacy-conscious users leaving cloud-dependent trackers (Oura, Whoop, Apple Watch)
- Biohackers and quantified-self users who want nervous system training with measurable outcomes
- Teams running a recovery-focused pilot with anonymized aggregates (no individual data leaves devices)

## Technical Stack

- **Mobile**: Flutter (Dart)
- **Engine**: C++ 17 (arm64), streaming frame API, CNN PeakValidator
- **AI Layer**: On-device interpretation, recommendation, pattern tracking, prediction (logistic regression + Thompson Sampling)
- **Hardware**: iPhone (iOS 15+) or Android (8.0+) with rear camera + LED flash
- **Health**: HealthKit / Health Connect integration
- **Security**: AES-256-GCM, local-only storage

## Pricing

- **Free**: 2 measurements/day, basic AI interpretation, all 28 breathing protocols
- **Shield+** ($29.90/mo): unlimited measurements, full AI interpretation + 24-48h stress prediction, personalized protocols, priority support
- **B2B pilot**: 2-week free pilot for teams of 10-30; anonymized aggregates only
- Free during the current beta

## Roadmap

- **v1.6.5** (current, App Store + Google Play): 28 breathing protocols, acupressure, Health integration, offline, privacy-first
- **v2.0** (TestFlight beta): camera-based nervous system measurement, on-device AI interpretation, recovery timeline
- **v3.0** (planned): recovery prediction 24-48h ahead, personal circadian profile, advanced personalization
