"The disappearance of children greatly affected families and investigators alike. Parents should download this app that also features tips on keeping kids safe," Andrew Colvin, Australian Federal Police Deputy Commissioner, said.

In case of a missing kid, first 12 to 24 hours are fundamentally critical."Information like photographs, dates of birth, habits of these children, friends, places they like to frequent can give police a good start," Colvin said.

In India where a child goes missing every eight minutes, such an app can come handy.

According to latest data from India's National Crime Records Bureau (NCRB), nearly 40 percent of missing children have never been found.

Children are kidnapped for human trafficking, illegal organ transplantation, prostitution, child porn, child labour in factories and unpaid domestic help.

Many children are forced to beg; some are mutilated to evoke sympathy for more earning potential and a small percentage for ransom, NCRB data revealed.
