## What is SoundSentry?

Stay focused. Let important sounds come to you.
SoundSentry listens in the background (microphone permission required) and uses iOS Sound Analysis to recognize common household sounds. When a selected sound is detected—like a baby crying, a dog barking, or a knock at the door—SoundSentry immediately sends a local notification so you can respond without taking off your headphones.

Great for

Working/studying at home with ANC headphones

Baby care: crying alerts and other cues

Pet care: barking or unusual activity

Home awareness: knocks and other events

Key Features

Choose what to detect: baby cry, dog bark, knocking, and more (availability depends on iOS support)

Instant local notifications: get alerted the moment a target sound is detected

Privacy-first design: analysis is intended to run on-device (no model training needed)

Permissions

Microphone: to listen and analyze sounds

Notifications: to alert you when a target sound is detected
No account required.

Disclaimer: Detection accuracy depends on distance, noise level, and device placement. For best results, place the device near the monitored area.
