Cryguard v1.00(14) is a mobile "babyphone" for Symbian s60 3rd and 5th edition.
It works by detecting audio volume level, and calling a phone number set in it when volume gets high enough. If the volume goes to yellow level, it makes an alarm if the sound is continuous. If the volume goes to red level, the alarm is instaneous. The application calls for a while, returns to listening, and again new alarm is made if necessary.

If several applications run at the same time, Nokia audio driver may crash = do not run other applications parallel to Cryguard.
