What features would you install in a machine learning app to help with parents’ caring duties of their kids?

Stage 1: time home from school, remaining battery life, anomalies in patterns of movement; inappropriate content alerts, daily routine habits, location tracking, unrecognised calls alerts.

Stage 2: social networks changes – work with psychologists to develop predictors or indicators of child bullying, such as sudden and mass friend loss on social media.

Stage 3: sleep monitoring and data and cues on indicators of mental health, mood detection.

This is not a thought experiment – it is what one of many parental awareneness app startups is working on.
