## NeuralPulse Automatic Build
100+
101+
### Phone app (Android 10+ / API 29+)
102+
- `NeuralPulse-phone-debug.apk` — sideload directly, no signing needed
103+
- `NeuralPulse-phone-release-unsigned.apk` — production build, needs signing
104+
105+
### Wear OS app (Wear OS 3+ / API 30+)
106+
- `NeuralPulse-wear-debug.apk` — sideload via ADB or Wear OS Assistant
107+
- `NeuralPulse-wear-release-unsigned.apk` — production build
108+
109+
### Device compatibility
110+
- **Phone**: Any Android 10+ device. Samsung Health SDK is optional; falls back to Health Connect on non-Samsung.
111+
- **Watch**: Any Wear OS 3+ watch. Samsung Health Sensor SDK is optional; falls back to Android Health Services on non-Galaxy watches.
