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.
