About NightGuard
Sleep peacefully, knowing NightGuard is listening.
NightGuard is a smart sleep sound monitor that listens for loud or unusual sounds while you sleep: Snoring, night terror episodes, or sudden distress, and alerts you or someone nearby in real time.
How it works:
Live decibel (dB) meter tracks sound levels as you sleep
Adjustable threshold slider — set your own sensitivity
Custom alert sound picker — choose the tone that wakes you (or a partner) without causing panic
Calibration mode — fine-tune detection to your room and environment
Who it's for:
Parents monitoring children with night terrors
Partners of people who snore heavily
Anyone who experiences nighttime distress, restlessness, or vocalizations during sleep
Veterans and others managing sleep disruptions, wanting an extra layer of awareness overnight
Light sleepers wanting peace of mind
NightGuard does not diagnose or treat any medical condition. It's a monitoring tool designed to give you awareness and peace of mind — not a replacement for professional medical advice.
No account required. No data leaves your device. Simple, private, and built to just work.
