App Description

iTrigger is a noise-detecting message-playing app. Record your own personal message or sound, set the sensitivity, turn on the sensor and wait for your recording to be triggered by a noise around your iPhone. Use it as a burglar alarm, a pet sitter or just for practical jokes. Using the sensitivity slider iTrigger can be adjusted to detect noises as quiet as a whisper or as loud as a party.
