## What is Noise Alert?

Noise Alert+ monitors ambient sound levels and instantly alerts you when noise exceeds your set threshold. Perfect as a baby monitor, sleep guardian, or noise watchdog.

Place your iPhone in the baby's room or any area you want to monitor. Set a decibel threshold, and the app will flash visual alerts and trigger notifications when sound levels spike — whether it's a baby crying, a dog barking, or unexpected loud noise.

Key Features:
- Real-time sound level monitoring in decibels
- Customizable noise threshold with instant alerts
- Visual and notification-based alert system
- Background monitoring mode
- Noise event log with timestamps
- Live decibel meter with peak tracking
- Sensitivity calibration
- Alert sound customization

Use it as a baby room monitor while you work in another room, as a noise complaint evidence tool, or as a hearing protection reminder in loud environments.
