Looking for an app to notify when an elderly person is inactive I am looking for an android app to install on the phone of an elderly person in my family so that when this person stops using the phone, say for one day, then I get notified somehow so that I check up on them and make sure they are ok. Does something like this already exist?

Thanks.
SeniorSafety on GooglePlay

This application has an inactivity option as well as fall notifications, gps tracking and other useful options for senior safety.
