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.
