User Manual - ZzzCatcher

1. Understanding the Noise Bar

The 'Current Noise Level' bar shows real-time sound activity.

Green Bar: Sound is below your trigger level.
Red Bar: Sound has crossed your threshold and a recording has been triggered.
Threshold Slider: Drag the slider to set your baseline. In a quiet room, we recommend -40dB to -30dB.

2. Auto-Start & Manual Controls

Monitoring starts automatically when you launch the app to ensure you never miss a session.

STOP/START: You can manually pause or resume monitoring using the circular button at the bottom of the screen.
Modes: Select Audio Only or Video & Audio Pro in the settings menu.

PRO TIPS FOR NIGHT VIDEO:

Use the Front Camera: The display’s "Night Light" provides direct illumination for clearer video in dark rooms.
Positioning: Face the screen toward you so the "Night Light" can shed light on the recording target directly.

3. Blackout Mode for Better Sleep

Once monitoring has started, tap the Moon icon to darken your screen. The app continues to listen in the background. To exit Blackout Mode, simply double-tap anywhere on the black screen.

4. Nightly Summary & Reports Pro

Pro users can tap the 'View Events' button at the top of any night in History to see a full dashboard including total sleep time, snore counts, and abnormal sound analysis. To export this summary, tap the Share icon in the top left corner of the event log to generate a shareable text report for your doctor.

5. Power-Optimized Monitoring

ZzzCatcher is designed with energy efficiency in mind. By utilizing event-triggered technology, the high-luminosity 'Night Light' and video sensors only activate during actual recording events. To ensure your session lasts all night without interruption, we still recommend keeping your device connected to a charger.

6. Privacy & Automatic Stop

To preserve your device's battery and protect your daytime privacy, ZzzCatcher will automatically stop monitoring after 12 hours. Monitoring will also automatically pause if you receive a phone call, and will resume automatically once the call has ended.

7. Review, Playback & Deletion

In the History view, your recordings are organized by date. Tap the Play icon next to any file to watch or listen.

Icons: Blue Mic = Audio, Purple Camera = Video, ⚠️ = Abnormal event (gasp/cough).
Playback: Tap the Play icon. Audio is automatically routed to your speaker for clear listening.
Deletion: Swipe left on a file to delete, or tap 'Delete All' next to a date header to clear the entire night. Tap the Trash icon in the top toolbar to clean up all files older than 3 (Free) or 30 (Pro) days.

8. Sharing & Exporting Pro

ZzzCatcher Pro allows you to export your data. You can tap the Share icon next to any individual file in the History list, or tap the Share icon while a video is playing. This is the best way to send specific snore or gasp events to a sleep specialist.

9. Smart Detection & Abnormal Events

Smart Snore Detection is now free for all users to ensure high-accuracy recordings. When enabled, a 'SMART AI' badge will appear, and a 'SNORE DETECTED' indicator will show when the AI identifies a snore. ZzzCatcher Pro adds advanced detection for abnormal sounds like gasping or coughing, automatically flagging those recordings with an '⚠️' icon in your history.
