My mother lives alone and we are concerned about how I will know if something has happened to her if I haven't talked to her for a few days. Our idea was to have her e-mail/text every couple days. These ideas, however, still seem to have some friction that make them less than ideal. She uses a computer daily and has the latest iPhone. Is there software (or IFTTT recipe) that the two of us can use that will alert me if she has been idle for some period of time? Something such as an alert if her phone doesn't move or she doesn't log into Facebook for a day?
To clarify, I live close to my mother and visit often. The intent of this question is to close the 24-hr gap in case of some medical emergency.
